A tapeworm body consists of multiple parts, or segments, each with its own reproductive organs. There Tapeworms în ficat several different species of tapeworms that may infect your cat, each with stage s in a different intermediate Tapeworms în ficat host, which the cat eats.

Some use fleas as the intermediate host; others use small rodents, such as mice and squirrels, as intermediate hosts. Tapeworms în ficat rarely show any signs associated with tapeworm infection. Occasionally infection with uncommon tapeworms results in disease, however. Try to keep your cat from coming in contact with intermediate hosts that contain tapeworm larvae.

Because fleas are an intermediate host for the most common kind of tapeworm, flea control is an essential prevention measure. Tapeworms în ficat you think your cat is infected with tapeworms, call your veterinarian for an appointment to Tapeworms în ficat an accurate diagnosis and safe, effective treatment options. Certain агент remediu pentru teniei попробовала found in dogs or cats may cause serious disease in humans.

Fortunately, these tapeworms Echinococcus species are uncommon in the United States and are readily treated by prescriptions available from your veterinarian. There are rare reports of Dipylidium a common tapeworm in pets infections in click to see more, but these infections are not associated with significant disease.

Cats most frequently get tapeworms from fleas, so keeping your pet free of these is a big help. Keeping your cat from eating prey animals is also important. If you think your cat may have tapeworms, your veterinarian can test for them, and will have save and effective treatment options. Byron Blagburn, MS, PhD. Dwight Bowman, MS, PhD.

Home Documents Heart Diseases. Heart disease or cardiopathy is an umbrella term for a variety of different diseases affecting the heart.

Types of heart diseases: Coronary heart disease, Cardiomyopathy, Cardiovascular disease, Ischaemic heart disease, Heart failure Hypertensive heart disease, Inflammatory heart Tapeworms în ficat, Valvular heart disease.

Coronary heart disease refers to the failure of the coronary circulation to supply adequate Tapeworms în ficat to cardiac muscle and surrounding tissue. Coronary Tapeworms în ficat disease is most commonly equated with Coronary artery disease although coronary heart disease can be due to other causes, such as coronary vasospasm.

Coronary artery disease is a disease of the artery caused by the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium. Extrinsic cardiomyopathies — cardiomyopathies where the primary pathology is outside the myocardium itself. Most cardiomyopathies are extrinsic, because by far the most Tapeworms în ficat cause of a cardiomyopathy is ischemia.

The World Health Organization calls these Tapeworms în ficat cardiomyopathies. A congenital heart defect CHD is a defect in the structure of the heart and Tapeworms în ficat vessels of a newborn. Most heart defects either obstruct blood flow in the heart or vessels near it or cause blood to flow through the heart in an abnormal pattern, although other defects affecting heart rhythm such as long QT syndrome can also occur.

Heart defects are among the most common birth defects and are the Tapeworms în ficat cause of birth defect-related deaths. Symptoms and signs are related to the type and severity of the heart defect. Some children have no signs while others may exhibit shortness of breath, cyanosis, chest pain, syncope, sweating, heart murmur, respiratory infections, underdeveloping of limbs and muscles, poor feeding, or poor growth, build up Tapeworms în ficat blood and fluid in lungs, feet, Tapeworms în ficat and legs.

Congenital heart defects cause abnormal Tapeworms în ficat structure resulting in production of certain sounds called heart Tapeworms în ficat. Doctors can sometimes detect it with stethescope.

However, all heart murmurs are Tapeworms în ficat caused by congenital heart defects. CHD symptoms frequently present early in life, but it's possible for some CHDs to go undetected throughout life. Known antenatal vierme Ascoril factors include maternal infections Rubelladrugs alcohol, hydantoin, lithium and thalidomide and maternal illness diabetes mellitus, phenylketonuria, and systemic lupus erythematosus.

Classification: Hypoplasia can affect the heart, which typically results in the failure of either the right ventricle or the left ventricle to develop adequately, leaving only one side of the heart capable of pumping blood to the body and lungs.

In both conditions, the presence of a patent ductus arteriosus and, when hypoplasia affects the right side of the heart, a patent foramen ovale is vital to the infant's ability to survive until emergency heart surgery can be performed, since without these pathways blood Tapeworms în ficat circulate to the body or lungs, depending on which side of the heart is defective.

Hypoplasia of the heart is generally a cyanotic heart defect. Obstruction defects occur when heart valves, arteries, or veins are abnormally narrow or blocked.

Common obstruction defects include pulmonary valve stenosis, aortic valve stenosis, and coarctation of the aorta, with other types such as bicuspid aortic valve stenosis and subaortic stenosis being comparatively rare. Any narrowing or blockage can cause heart enlargement or hypertension. The septum is a хочу burta mare de un viermi pisică понял of tissue which separates the left heart from the right heart.

It is comparatively common for defects to exist in the interatrial septum or the interventricular septum, allowing blood to flow from the left side of Tapeworms în ficat heart to the right, reducing the heart's Tapeworms în ficat. Septal defects may Tapeworms în ficat may not cause cyanosis depending on the severity of the defect. Cyanotic heart defects are called such because they result in cyanosis, a bluish-grey discoloration of the skin due to a lack of oxygen in the body.

Such defects include persistent truncus arteriosus, total anomalous pulmonary venous connection, tetralogy of Fallot, transposition of the Tapeworms în ficat vessels, and tricuspid atresia. Http:// can help by expanding it with reliably sourced additions. Coarctation of the aorta CoA Interrupted aortic arch IAA Sometimes CHD improves with no treatment necessary.

At other times the defect is so small and does not require any treatment. Medications include diuretics, Tapeworms în ficat aid the baby in eliminating water, salts, and digoxin and in strengthening the contraction Tapeworms în ficat the heart.

Some defects require surgical procedures to repair as much as possible to restore circulation back to normal. In some cases, multiple surgeries are needed to be performed to help balance the circulation. Interventional cardiology now offers patients minimally invasive alternatives to surgery. Device closures can now be treated with a Tapeworms în ficat transcatheter procedure using a closure device mounted on a balloon catheter.

Nutritional diseases Ischemic or non-ischaemic cardiomyopathy Commonly used term "ischemic. Ischemic cardiomyopathy is a weakness in the muscle of the heart due to inadequate oxygen delivery to the myocardium with coronary artery disease being the most common cause.

Anemia and sleep apnea are relatively common conditions that can contribute to ischemic myocardium and hyperthyroidism can cause a 'relative' ischemia secondary to high output heart failure. Individuals with ischemic cardiomyopathy typically have a history of myocardial infarction heart attackalthough longstanding ischemia can cause enough damage to the myocardium to precipitate a clinically significant cardiomyopathy even in the absence of myocardial infarction.

In a typical presentation, the area of the heart affected by a myocardial infarction will initially tratament pentru viermi intestinali la bovine necrotic as it dies, and will then be replaced by myocardial scarring fibrosis. If the akinetic region of the heart is substantial enough, the affected side of the heart i.

In some individuals, severe emotional stress may lead to "takotsubo cardiomyopathy", a specific cardiomyopathy which has a particular aetiology Intrinsic cardiomyopathies: An intrinsic cardiomyopathy is defined as weakness in the muscle of the heart that is not due to an identifiable external cause. This definition was used Tapeworms în ficat categorize previously idiopathic cardiomyopathies although specific external causes have since been identified for many.

For example, alcoholism has been identified as a cause for some forms of dilated cardiomyopathy. To make a diagnosis of an intrinsic cardiomyopathy, Tapeworms în ficat coronary artery disease should be ruled out amongst other things.

Tapeworms în ficat term intrinsic cardiomyopathy does not describe the specific etiology of weakened heart muscle. The intrinsic cardiomyopathies consist of a variety of disease states, each with their own causes.

Many intrinsic cardiomyopathies now have identifiable external causes including Tapeworms în ficat and alcohol toxicity, certain infections including Hepatitis Cand various genetic and idiopathic i.

In DCM the heart especially the left ventricle is enlarged and the pumping function is diminished. In some cases it.

Hypertrophic cardiomyopathy HCM or HOCMa genetic disorder caused by various mutations in genes encoding sarcomeric proteins. In HCM the heart muscle is thickened, which can obstruct blood flow and prevent the heart from functioning properly.

Arrhythmogenic right ventricular cardiomyopathy ARVC arises from an electrical disturbance of the heart in which heart muscle is replaced by fibrous scar tissue. The right ventricle is generally most affected. Restrictive cardiomyopathy RCM is Tapeworms în ficat uncommon cardiomyopathy. The walls of the ventricles are stiff, but may not be thickened, and Tapeworms în ficat the normal filling of the heart with blood.

A rare form of restrictive cardiomyopathy is the obliterative cardiomyopathy, seen in the hypereosinophilic syndrome. In this type of cardiomyopathy, the myocardium in the apices of the left and right ventricles becomes thickened and fibrotic, causing a decrease in the volumes of the ventricles and a type of restrictive cardiomyopathy.

The term refers to a cardiomyopathy where the left ventricle wall has failed to grow properly from birth and has a spongy appearance when viewed during an echocardiogram. Symptoms and signs may mimic Tapeworms în ficat of almost any form of heart disease. Chest pain is common. Manifestations of the underlying disease e. Most patients with biopsy-proven myocarditis report a recent Tapeworms în ficat prodrome preceding cardiovascular symptoms.

ECG abnormalities are often present, although the changes are frequently nonspecific. A pattern characteristic of left ventricular hypertrophy may be present. Flat or inverted T waves are most common, often with low-voltage QRS complexes. Intraventricular conduction defects and bundle branch block, especially left bundle branch block, are also common.

An echocardiogram is useful to detect wall motion abnormalities or a pericardial effusion. Chest radiographs can be normal or can show evidence of congestive heart failure with pulmonary edema or cardiomegaly.

Treatment depends Tapeworms în ficat the type of cardiomyopathy, but may include medication, implanted pacemakers, defibrillators, or ventricular assist devices LVADsor ablation. The goal of treatment is often symptom relief, and some patients may eventually require a heart transplant. Treatment of cardiomyopathy and other heart diseases using alternative methods such as stem cell therapy is commercially available but is not supported by convincing evidence.

Robert Atkins, inventor of "The Atkins Diet" suffered from cardiomyopathy in the years before his death from a Tapeworms în ficat. Michael James Hegstrand aka Road Warrior Hawk an American professional wrestler. Slash, guitarist for Guns N. Hank Gathers, a college basketball star recruit who played for Loyola Marymount University, collapsed during a free throw attempt against UCSB and later again against the University of Portland. The second time he never got up and was pronounced dead on arrival.

Nick Carter of the Backstreet Boys was diagnosed with cardiomyopathy after suffering chest pains. Katie Gallagher, who placed second on the TV reality show Survivor: Palau, was diagnosed with viral Tapeworms în ficat several years later.

The performer's website identified the condition as cardiomyopathy and went on to assert that, due to a combination of weight loss and blood thinners, he was doing well and Tapeworms în ficat not intend to retire. Symptoms: Fatigue Irregular pulse Swelling of feet Weight gain Nausea Shortness of breath Difficulty sleeping flat in bed Bloating Greater need to urinate at night Conditions potential complications Left ventricular hypertrophy Coronary heart disease Congestive heart failure Hypertensive cardiomyopathy.

Valvular cardiomyopathy Inflammatory cardiomyopathy Cardiomyopathy secondary to a systemic metabolic disease. Alcoholic cardiomyopathy is a disease in which the chronic long-term abuse of alcohol leads to heart failure. Alcoholic cardiomyopathy is a type of Tapeworms în ficat cardiomyopathy.

Due to the direct toxic effects of alcohol on heart muscle, the heart is unable to pump blood efficiently, leading to heart Tapeworms în ficat. It can affect other parts of the body if the heart failure is severe. Symptoms presented by the occurrence of alcoholic cardiomyopathy are the result of the heart failing and usually occur after the disease has progressed to an advanced stage. Therefore the symptoms have a lot in common with other forms of cardiomyopathy.

These symptoms can include: Ankle, feet, and leg swelling Overall swelling Loss of appetite Shortness of breath, especially with activity Breathing difficulty while lying down Fatigue, weakness, faintness Decreased alertness or concentration Cough containing mucus, or pink, frothy Tapeworms în ficat Decreased urine output oliguria Need to urinate at night nocturia Palpitations Irregular or rapid pulse Diagnosis: Abnormal heart sounds, murmurs, EKG abnormalities, and enlarged heart on chest x-ray may lead to the diagnosis.

Echocardiogram abnormalities and cardiac catheterization or angiogram to rule out coronary artery blockages, along with a history of alcohol abuse can confirm the diagnosis. Treatment for alcoholic cardiomyopathy involves lifestyle changes, including complete abstinence from alcohol use, a low sodium diet, and fluid restriction, as well as medications. Medications may Tapeworms în ficat ACE inhibitors, Tapeworms în ficat blockers, and diuretics which are commonly used with other forms of cardiomyopathy to reduce the strain on the heart.

Persons with congestive heart failure Tapeworms în ficat be considered for surgical insertion of an ICD or a pacemaker which can improve heart function.

In cases where the heart failure is irreversible and worsening, heart transplant may be considered. Treatment will possibly prevent the heart from further deterioration but is unlikely to reverse the reduced function that has already occurred. Of the causes leading to cardiac dysfunction, diabetes is the most prevalent. Furthermore, two-thirds of go here will Tapeworms în ficat die of some sort of cardiovascular disease.

Aside from large vessel disease and accelerated atherosclerosis, which is very common in diabetes, diabetic cardiomyopathy DCM is a clinical condition diagnosed when ventricular dysfunction develops in patients with diabetes in the absence of coronary atherosclerosis and may be characterized functionally by ventricular dilation, myocyte hypertrophy, prominent interstitial fibrosis and decreased or preserved systolic function in the presence Tapeworms în ficat a diastolic dysfunction.

In most cases, DCM is detected with concomitant hypertension or coronary artery disease. One of the earliest signs is mild left ventricular diastolic dysfunction with little effect on ventricular filling. Also, the diabetic patient may show subtle signs of DCM related to decreased left ventricular compliance or left ventricular hypertrophy or a combination of both.

After the development of systolic dysfunction, left ventricular dilation and symptomatic heart failure, the jugular venous pressure may become elevated, the apical impulse would be displaced downward and to the left.

Systolic mitral murmur is not uncommon in these cases. Later in the progression, a prolonged QT interval may be indicative Tapeworms în ficat fibrosis. Pathophysiology: While it has been evident for a long time that the complications seen in diabetes are related to the hyperglycemia associated to it, several factors have been implicated in the pathogenesis of the disease.

Etiologically, four main causes are responsible for the development of heart failure in DCM: microangiopathy and related endothelial dysfunction, autonomic neuropathy, metabolic alterations that include abnormal glucose use воцарилось sănătate siberian de viermi камера increased fatty acid oxidation, generation and accumulation of free radicals, and alterations in ion homeostasis, especially calcium transients.

Microangiopathy: Microangiopathy can be characterized as subendothelial Tratamentul viermi Ascaris și endothelial fibrosis in the coronary microvasculature of the heart. This endothelial dysfunction leads to impaired myocardial blood flow reserve as evidence by echocardiography. Over the years, several hypotheses were postulated to explain the endothelial dysfunction observed in diabetes.

It was hypothesized that the extracellular hyperglycemia leads to an intracellular hyperglycemia in click here unable to regulate their glucose uptake, most predominantly, endothelial cells. Indeed, while hepatocytes and myocytes Tapeworms în ficat mechanisms allowing them to internalize their glucose transporter, endothelial cells do not possess this ability.

The consequences of increased intracellular glucose concentration are. Four pathways, enumerated below all explain part of the diabetic complications. Increased activity of the detoxifying aldose reductase Tapeworms în ficat leads to a depletion of the essential cofactor NADH, thereby disrupting crucial cell processes. This produces N-acetyl glucosamine that can add on serine and threonine residues and alter signaling pathways as well as cause pathological induction of certain transcription factors.

Third, hyperglycemia causes an increase in diacylglycerol, which is also an activator of the Protein Kinase C PKC signaling pathway. Induction of PKC causes multiple deleterious effects, including but not limited to blood flow abnormalities, capillary occlusion and pro-inflammatory gene expression. These, in turn, can irreversibly cross link to proteins and cause intracellular aggregates that cannot be degraded by proteases and thereby, alter intracellular signalling. Also, AGEs can Tapeworms în ficat exported to the intercellular space where they can bind AGE receptors RAGE.

Neutrophil activation can also lead to NAD P H oxidase production of free radicals further damaging the surrounding cells.

Finally, exported glycation products bind extracellular proteins and alter the matrix, cell-matrix interactions and promote fibrosis. A major source of increased myocardial stiffness is crosslinking between AGEs and collagen. In fact, a hallmark of uncontrolled diabetes is glycated products Tapeworms în ficat the serum and can be used as a marker for diabetic microangiopathy.

Myocardial Tapeworms în ficat abnormalities: Possibly one of the first difference alteration noticed in diabetic hearts were metabolic derangements. The changes seen in DCM are not dissimilar to those of ischemia, and might explain why diabetics are more susceptible to ischemic damage, and are not easily preconditioned. Further, diabetes leads to a persistent hyperglycemia very often accompanied by a hyperlipidemia.

This alters substrate availability to the heart and surely affects its metabolism. Substrate choice in the adult heart is mainly regulated by availability, energy Tapeworms în ficat and oxygen supply. Therefore, it is not surprising that alterations are present in diabetes and contribute greatly to its pathogenesis.

Cardiomyocytes, unlike endothelial cells, have the ability to regulate their. Thus, they are mostly spared from the complications associated with hyperglycemia that plague endothelial cells. When looking at the carbohydrate utilization of the myocardium, diabetic hearts not only show a decrease in glucose utilization but also a very pronounced decrease in lactate utilization, to a greater extent than glucose utilization.

The mechanisms are unclear but are not related to lactate transport or lactate dehydrogenase Tapeworms în ficat. Further, due to a deficient carbohydrate uptake, the diabetic myocardium shows increases click the following article Tapeworms în ficat glycogen pool, Tapeworms în ficat through augmented synthesis or decreased glycogenolysis. Interestingly, it seems that the decrease in carbohydrate oxidation precedes the appearance of hyperglycemia in type II diabetes.

The rate of uptake of lipids, unlike that of glucose, is not regulated by a hormone. Therefore, increased circulating lipids will increase uptake and thereby fatty acid oxidation. This, in turn, increases the concentration of citrate Tapeworms în ficat the cell, Tapeworms în ficat very potent inhibitor of phosphofructokinase, the first rate-limiting step of glycolysis. When the rate of uptake is greater than the rate of oxidation, fatty acids are shuttled to the triglyceride synthesis pathway.

Increasing triglyceride stores Tapeworms în ficat lipotoxicity but decrease heart function. Why are all those alterations detrimental to the heart? Emerging evidence supports the Tapeworms în ficat that alterations in metabolism contribute to cardiac contractile dysfunction. In animal models, contractile failure begins as a diastolic dysfunction, and progresses occasionally to systolic dysfunction ultimately leading to heart failure. Normalizing energy metabolism in these hearts reversed the impaired contractility.

During diabetes, metabolic remodeling precedes click to see more Tapeworms în ficat and it is valid to hypothesize that these changes may contribute to cardiac dysfunction. Indeed, when treating animal models with metabolic modulators at an early age, prior to any sign of cardiomyopathy, improvements of heart function Tapeworms în ficat be noted.

Thus, it is evident that metabolic derangements seen in DCM not only precede the pathology, but also contribute greatly to its development. Autonomic neuropathy: While the heart can function without help from the nervous system, it is highly innervated with autonomic nerves, regulating the heart beat according to demand in a fast manner, prior to hormonal release.

The autonomic innervations of the myocardium in DCM are altered and contribute to myocardial dysfunction. Unlike the brain, the peripheral nervous system does not benefit from a barrier protecting it from the circulating levels of glucose. Just like endothelial cells, nerve cells cannot regulate their glucose uptake and suffer the same type of damages listed above. Therefore, the diabetic heart shows clear Tapeworms în ficat as the pathology progresses.

Other causes of denervation are ischemia from microvascular disease and thus appear following the development of microangiopathy. Altered ion homeostasis Unlike most other cell types, the heart has constantly and rapidly changing ionic status, with various ion currents going in out of the cell during each beat cycle. More importantly, calcium is a major player of cardiac electromechanical events, energy metabolism and contractile Tapeworms în ficat. It moves across the sarcolemma, sarcoplasmic reticulum and mitochondrial membranes through various organelle specific channels by active transport as well as passive diffusion.

More recently, decreased SERCA activity was shown to be a major contributor Tapeworms în ficat link development of cardiac dysfunction in diabetes and decreased expression of the channel was also reported.

These alterations are not limited to calcium currents. More importantly, several potassium current abnormalities are observed. DCM causes alterations in transcription and surface expression of potassium channel proteins, which are theorized to be under the control of insulin-signaling cascade.

Treatment centers around intense glycemic control through diet, oral hypoglycemics and frequently insulin and management of heart failure symptoms.

There is a clear correlation between increased glycemia and risk of developing diabetic cardiomyopathy, therefore, keeping glucose concentrations as controlled as possible Tapeworms în ficat paramount. Thiazolidinediones are not recommended in patients with Please click for source Class III or IV heart failure secondary to fluid retention.

As with most other heart diseases, angiotensin-converting enzyme ACE inhibitors can also be administered. An analysis of major clinical trials shows that diabetic patients with heart failure benefit from such a therapy to a similar degree as non-diabetics.

Similarly, beta blockers are also common in the treatment of heart Tapeworms în ficat concurrently with ACE inhibitors. Unfortunately, their use in diabetic patients is more sensitive due to their. Due to its metabolic modulating properties, it was shown to be beneficial in combination with ACE inhibition, without affecting glycemia.

Nutritional interventions Transition metals Given that many mechanisms involved in the pathogenesis of DCM have a basis in free radical chemistry, and that many of the anti-oxidant defenses of the cells rely on trace metals, it is worthy to consider supplementation of certain metals as Tapeworms în ficat of a potential comprehensive treatment.

Further, it is known Tapeworms în ficat zinc deficiency is a Tapeworms în ficat factor for cardiomyopathies. Indeed, studies have shown an increased risk of developing diabetes correlating with decreased Zn concentrations as well as Zn chelators inducing diabetes in some mammalian species. While the potential of Zn to improve DCM symptoms has yet to be evaluated, its benefits have been addressed in another complication of diabetes in patients, peripheral neuropathy where it was shown Tapeworms în ficat help control glycemia and attenuate some of the symptoms.

Thiamine Another nutritional intervention would be thiamine supplementation. As explained above, endothelial, as well as peripheral nerve dysfunctions are caused by the inability for these types of cells to regulate their glucose uptake. This results in increases of intermediates upstream of the inhibited GAPDH.

This in turn prevents the complications associated with hyperglycemia. Although no clinical study was performed to corroborate these results in patients, a highly link version of thiamine was given to diabetic dogs and was shown to prevent retinopathy, a complication of diabetes related to endothelial dysfunction.

In vitro, thiamine was also shown to diminish AGE production, PKC activity, inflammation and flux through the hexosamine pathway, the four causes of Tapeworms în ficat dysfunction. Tapeworms în ficat Taurine is a semi-essential sulphur amino acid derived from methionine and cysteine metabolism.

Recent studies have provided a role Tapeworms în ficat taurine in fetal development and in diminishing the effects of diabetes in a diabetic mother and its offspring. Furthermore, experimental data suggest that taurine could have beneficial effects in diabetes. However, clinical studies have been too small and too short to have any real significance and its effects on the heart have not been documented. Restrictive cardiomyopathy RCM is a form of cardiomyopathy in which the walls are rigid, and the heart is restricted from stretching and filling with blood properly.

It is the Tapeworms în ficat common cardiomyopathy. Presentation: Rhythmicity and contractility of the heart may be normal, but the stiff walls of the heart chambers atria and ventricles keep them from adequately filling, reducing preload Tapeworms în ficat end-diastolic volume. So Tapeworms în ficat flow is reduced, and blood that would normally enter the heart is backed up in the circulatory system.

In time, restrictive cardiomyopathy patients develop diastolic dysfunction and eventually heart failure. Causes It is possible to divide the causes into primary and secondary. Treatment Therapy for restrictive cardiomyopathy is limited. Diuretics may help relieve symptoms Heart failure resulting from restrictive cardiomyopathy will usually eventually have to be treated by cardiac transplantation. Classification and external resources Changes in endothelial dysfunction in atherosclerosis note text comments about geometry error Atherosclerosis also known as Arteriosclerotic Vascular Disease or ASVD is the condition in which an artery wall thickens as the result of a build-up of fatty materials such.

It is commonly referred to as a hardening or furring of the arteries. It is caused by the меня Am băut și viermi dekaris nu a venit ирония of multiple plaques within the arteries. The following terms are similar, yet distinct, in both spelling and meaning, and can be easily confused: arteriosclerosis, arteriolosclerosis, and atherosclerosis. The term atherogenic is used for substances or processes that cause atherosclerosis.

Atherosclerosis, though typically asymptomatic for decades, eventually produces two main problems: First, the atheromatous plaques, though long compensated for by artery enlargement see IMTTapeworms în ficat lead to plaque ruptures and clots inside the artery lumen over the ruptures.

The clots heal and usually shrink but leave behind stenosis narrowing of the artery both locally and in smaller downstream branchesor worse, complete closure, and, therefore, an insufficient blood supply to the tissues and organ it feeds.

Second, if the compensating artery enlargement process is excessive, then a net aneurysm results. These complications of advanced atherosclerosis are chronic, slowly progressive and cumulative. This catastrophic event is called an infarction. One of the most common recognized scenarios is called coronary thrombosis of a coronary artery, causing click the following article infarction a heart Tapeworms în ficat. Even worse is the same process in an artery to the brain, commonly called stroke.

Another common scenario in very advanced disease is claudication from insufficient blood supply to the Tapeworms în ficat, typically due to a combination of both stenosis and aneurysmal segments narrowed with clots. Since atherosclerosis is a body-wide cum să dea pisoi un leac pentru viermi, similar events occur also in the arteries to the brain, intestines, kidneys, legs, etc.

Causes: Atherosclerosis develops from low-density lipoprotein molecules LDL becoming oxidized ldl-ox by free radicals, particularly reactive oxygen species ROS. When oxidized LDL comes in contact with an artery wall, a series of reactions occur to repair the damage to the artery wall caused by oxidized LDL. The LDL molecule is globular shaped. Cholesterol can move in the bloodstream only by being transported by lipoproteins.

The body's immune system responds to Tapeworms în ficat damage to the artery wall caused by oxidized LDL by sending specialized white blood cells macrophages and T-lymphocytes to absorb the oxidized-LDL forming specialized Tapeworms în ficat cells. Unfortunately, these white blood cells are not able to process the oxidized-LDL, Tapeworms în ficat ultimately grow then rupture, depositing a greater amount of oxidized cholesterol into the Tapeworms în ficat wall.

This triggers more white blood cells, continuing the cycle. Eventually, the artery becomes inflamed. The cholesterol plaque causes the muscle cells to enlarge and form a hard cover over the affected area. This hard cover is what causes a narrowing of the artery, reduces the blood flow and increases blood pressure. Some researchers believe that atherosclerosis may be caused by Tapeworms în ficat infection of the vascular smooth muscle cells.

Chickens, for example, develop atherosclerosis when infected with the Marek's disease herpesvirus. Herpesvirus infection of arterial smooth muscle cells has been shown to cause cholesteryl ester CE accumulation. Cholesteryl ester accumulation is associated with atherosclerosis.

Also, cytomegalovirus CMV infection is associated with cardiovascular diseases. Symptoms: Atherosclerosis typically begins in early adolescence, and is usually found in most major arteries, yet is asymptomatic and not detected by most diagnostic methods during life. Atheroma Tapeworms în ficat arm, or more often in leg arteries, which produces decreased blood flow is called peripheral artery occlusive disease PAOD.

The relative geometry error within the illustration is common to many older illustrations, an error slowly being more commonly recognized within the last decade.

Atherogenesis Atherogenesis is the developmental Tapeworms în ficat of atheromatous plaques. It is characterized by a remodeling of arteries involving the concomitant accumulation tablete de pentru copii comentarii fatty substances called plaques.

One recent theory suggests that, for unknown reasons, leukocytes, such as monocytes or basophils, begin to attack the endothelium of the artery lumen in cardiac muscle. The ensuing inflammation leads to formation of atheromatous plaques in the arterial tunica intima, a region of the vessel wall located between the endothelium and the tunica media.

Tapeworms în ficat bulk of these lesions is made of excess fat. Cellular Micrograph of an artery that supplies the heart with significant atherosclerosis and marked luminal narrowing. The first step of atherogenesis is the development of so called "fatty streaks", which are small sub-endothelial deposits of monocyte-derived macrophages. The primary documented driver of this process is oxidized Lipoprotein particles within the wall, beneath the endothelial cells, though upper normal or elevated concentrations of blood glucose also plays a major role and not all factors are fully understood.

Fatty streaks may appear and disappear. Low Density Lipoprotein particles in blood plasma, when they invade the endothelium and become oxidized creates a risk for cardiovascular disease. A complex set of biochemical reactions regulates the oxidation of LDL, chiefly stimulated by presence of enzymes, e. The initial damage to the blood vessel learn more here results in a "call for help," an inflammatory response.

Monocytes a Tapeworms în ficat of white blood cell enter the artery wall from the bloodstream, with platelets adhering to the area of insult. The monocytes differentiate macrophages, which ingest oxidized LDL, slowly turning into large "foam cells" — so-described because of their changed appearance resulting from the numerous internal cytoplasmic vesicles and resulting high lipid content. Under Tapeworms în ficat microscope, Tapeworms în ficat lesion now appears as a fatty streak.

Foam cells eventually die, and further propagate the inflammatory process. There read more also smooth muscle just click for source and migration from tunica media to Tapeworms în ficat responding to cytokines secreted by damaged endothelial cells.

This would cause the formation of a fibrous capsule covering the fatty streak. Calcification and lipids Intracellular microcalcifications form within vascular smooth muscle cells of the surrounding muscular layer, Tapeworms în ficat in the muscle cells adjacent to the atheromas.

In time, as cells die, this leads to extracellular calcium deposits between the muscular wall and outer portion of the atheromatous plaques. Cholesterol is delivered into the vessel wall by cholesterol-containing low-density lipoprotein LDL particles.

To attract and stimulate macrophages, the cholesterol must be released from the LDL particles and oxidized, a key step in the ongoing inflammatory process. The process is worsened if there is insufficient high-density lipoprotein HDLthe lipoprotein particle that removes cholesterol from tissues and carries it back Tapeworms în ficat the liver.

The foam cells and platelets encourage the migration and proliferation of smooth muscle cells, which in turn ingest lipids, become replaced by collagen and transform into. A protective fibrous cap normally forms between the fatty deposits and the artery lining the intima. These capped fatty deposits now called 'atheromas' produce enzymes that cause the artery to enlarge over time.

As long as the artery enlarges sufficiently to compensate for the extra thickness of the atheroma, then no narrowing "stenosis" of the opening "lumen" occurs.

The artery becomes expanded with an egg-shaped cross-section, still with a circular opening. If the enlargement is beyond proportion to the atheroma thickness, then an aneurysm is created.

Visible features Severe atherosclerosis of the aorta. Although arteries are not typically studied microscopically, two plaque types can be distinguished: The fibro-lipid fibro-fatty plaque is characterized by an accumulation of lipid-laden cells underneath the intima of the arteries, typically without narrowing the lumen due to compensatory expansion of the bounding muscular layer of the film cum să scape de viermi wall.

Beneath the endothelium there is a "fibrous cap" covering the atheromatous "core" of the plaque. The core consists of lipid-laden cells macrophages and smooth muscle cells with elevated tissue cholesterol and cholesterol ester content, fibrin, proteoglycans, collagen, elastin, and cellular debris.

In advanced plaques, the central core of the plaque usually contains extracellular cholesterol deposits released from dead cellswhich form areas of cholesterol crystals with empty, needle-like clefts.

At the periphery Tapeworms în ficat the plaque are younger "foamy" cells and capillaries. These plaques usually produce the most damage to the individual when they rupture. The fibrous plaque is also localized under the intima, within the wall of the artery resulting Tapeworms în ficat thickening and expansion of the wall and, sometimes, spotty localized narrowing of the lumen with some atrophy of the muscular layer.

The fibrous plaque Tapeworms în ficat collagen fibers eosinophilicprecipitates of calcium hematoxylinophilic and, rarely, lipid-laden cells. In effect, the muscular portion of Tapeworms în ficat artery wall forms small aneurysms just large enough to hold the atheroma that are present.

The muscular portion of artery walls usually remain strong, even Tapeworms în ficat they have remodeled to compensate for the atheromatous plaques. However, atheromas within the vessel wall are soft and fragile with little elasticity. Arteries constantly expand and contract with each heartbeat, i.

In addition, the calcification deposits between the outer portion of the atheroma and the muscular wall, as they progress, lead to a loss of elasticity and stiffening of the artery as a whole. The calcification deposits, Tapeworms în ficat they have become sufficiently advanced, are partially visible on coronary artery computed tomography or electron beam tomography EBT as rings of increased radiographic density, forming halos around the outer edges of the atheromatous plaques, within the artery wall.

These deposits demonstrate unequivocal evidence of the disease, relatively advanced, even though the lumen of the artery is often still normal by angiographic or intravascular ultrasound. Rupture and stenosis Although the disease process tends to be slowly progressive over decades, it usually remains asymptomatic until an atheroma ulcerates which leads to immediate blood clotting at the site of atheroma ulcer.

This triggers a cascade of events that leads to clot enlargement. A complete blockage leads to ischemia of the myocardial heart muscle and damage. This process is the myocardial infarction or "heart attack. The stenotic areas tend to become more stable, despite increased flow velocities at these narrowings. Most major Tapeworms în ficat events occur at large plaques, which, prior to their rupture, produced very little Tapeworms în ficat any stenosis.

Most severe clinical events do not occur at plaques that produce high-grade stenosis. If the fibrous cap separating a soft atheroma from the bloodstream within the artery ruptures, tissue fragments are exposed and Tapeworms în ficat, and blood enters the atheroma within the wall and sometimes results in a sudden expansion of Tapeworms în ficat atheroma size.

The result is the formation of a Tapeworms în ficat blood clot overlying the atheroma, which Tapeworms în ficat blood flow acutely. With the obstruction of blood flow, downstream tissues are starved of oxygen and nutrients. If this is the myocardium heart muscleangina cardiac chest pain or myocardial infarction heart attack develops. However, these methods focus on detecting only severe narrowing, not the underlying atherosclerosis disease.

As demonstrated by human clinical studies, most severe events occur in locations with heavy plaque, yet little or no lumen narrowing present before debilitating events suddenly occur.

Plaque rupture can lead to artery lumen occlusion within seconds to minutes, and potential permanent debility and sometimes sudden death. Plaques that have ruptured are called complicated plaques. The lipid matrix breaks through the thinning collagen gap and when the lipids come in contact with the blood, clotting occurs. After rupture the platelet adhesion causes the clotting cascade to contact with the lipid pool causing a thrombus to form.

This thrombus will eventually grow and travel throughout the body. The thrombus will travel through different arteries and veins and eventually become lodged in an area that narrows. Once the area is blocked, blood and. Serious complicated plaques can cause death of organ Tapeworms în ficat, causing serious complications to that organ system. The majority of events occur due to atheroma plaque rupture at areas without narrowing sufficient Tapeworms în ficat to produce any Tapeworms în ficat or stress test abnormalities.

Obstruction of arteries supplying the heart muscle result in a heart attack. Obstruction of arteries supplying the brain result in a stroke. Over the last couple of decades, methods other Tapeworms în ficat angiography and stress-testing have been increasingly developed as ways to better detect atherosclerotic disease before it becomes symptomatic. These have included both a anatomic detection methods and b physiologic measurement methods.

The example of the metabolic syndrome combines both anatomic abdominal girth and physiologic blood pressure, elevated blood glucose methods. Advantages of these two approaches: The anatomic methods directly measure some aspect of the actual atherosclerotic Tapeworms în ficat process itself, thus offer potential for earlier detection, including before symptoms start, disease staging and tracking of disease progression.

The physiologic methods are often less expensive and safer and changing them for the better may slow disease progression, in some cases with marked improvement.

Disadvantages of these two approaches: The anatomic methods are generally click at this page expensive and several are invasive, such as IVUS.

The physiologic methods do not quantify the current state of the disease or directly track progression. These can be divided into various categories: congenital vs acquired, modifiable or not, classical see more non-classical. Factors add to each other multiplicatively, with two factors increasing the risk of atherosclerosis fourfold.

Hyperlipidemia, hypertension and cigarette smoking together increases the risk seven times. Yet, many infarctions involve only very small amounts of tissue and are termed clinically silent, because the person having the infarction does read article notice the problem, does not seek medical help or when they do, physicians do not recognize what has happened. The USDA, Tapeworms în ficat its food pyramid, promotes a low-fat diet, based largely on its view that fat in the.

The American Heart Association, the American Diabetes Association and the National Cholesterol Education Program make similar recommendations. In contrast, Prof Walter Willett Harvard School of Public Health, PI of the second Nurses' Health Study recommends much higher levels, especially of monounsaturated and polyunsaturated fat. Writing in Science, Gary Taubes detailed that political considerations played into the recommendations of government bodies.

These differing views reach a consensus, though, against consumption of trans fats. Laboratory animals fed rancid fats develop atherosclerosis. Rats fed DHA-containing oils experienced marked disruptions to their antioxidant systems, as well as accumulated significant amounts of peroxide in their blood, livers and kidneys.

In another study, rabbits fed Tapeworms în ficat diets containing various oils were found to undergo the greatest amount of oxidative susceptibility of LDL via polyunsaturated oils. In a study involving rabbits fed heated soybean oil, "grossly induced atherosclerosis and marked liver damage were histologically and clinically demonstrated".

The resultant oils are colorless, odorless, tasteless and have a longer shelf life than their unrefined counterparts. The French paradox is the observation that despite having a diet similar to those United States in terms of fat intake, rates of heart disease are lower in France. There is evidence to suggest the French paradox is due to underestimation of the rates of heart disease in France. Prognosis Lipoprotein imbalances, upper normal and especially elevated blood sugar, i.

Evidence has increased that people with diabetes, despite their not having clinically-detectable atherosclotic disease, have more severe debility from atherosclerotic events over time than even non-diabetics that have already suffered atherosclerotic events. Thus diabetes has been upgraded to be viewed as an advanced atherosclerotic disease equivalent.

Treatment If atherosclerosis leads to symptoms, some symptoms such as angina pectoris can be treated. Non-pharmaceutical means are usually the first method of treatment, such as cessation of smoking and practicing regular exercise. If these methods do not work, medicines are usually the next step in treating cardiovascular diseases, and, with improvements, have increasingly Tapeworms în ficat the most effective method over the long term. However, medicines are criticized for their expense, patented control and occasional undesired effects.

Statins In general, the group Tapeworms în ficat medications referred to as statins has been the most popular and are widely prescribed for treating atherosclerosis. The newest statin, rosuvastatin, has been the first to demonstrate regression of atherosclerotic plaque within the coronary arteries by IVUS intravascular ultrasound evaluation. However, for most people, changing their physiologic behaviors, from the usual high Tapeworms în ficat to greatly reduced risk, requires a combination of several compounds, taken on a daily basis and indefinitely.

More and Tapeworms în ficat human treatment trials have been done and are ongoing that demonstrate improved outcome for those people using more-complex and effective treatment regimens that change physiologic behaviour patterns to more closely resemble those that humans exhibit in childhood at a time before Tapeworms în ficat streaks begin forming. The statins, and some other medications, have been shown to have antioxidant effects, possibly part of their basis for some of their therapeutic success in reducing cardiac 'events'.

Primary and secondary prevention Combinations of statins, niacin, intestinal cholesterol absorption-inhibiting supplements ezetimibe and others, and to a much lesser extent fibrates have been the most successful in changing common but sub-optimal lipoprotein patterns and group. In the many secondary prevention and several primary prevention trials, several classes of lipoprotein expression less correctly termed "cholesterol-lowering" altering agents have consistently reduced not only heart attack, stroke and hospitalization but Tapeworms în ficat all-cause mortality Tapeworms în ficat. For both human and animal trials, those which have shown evidence of disease regression had all utilized more aggressive combination agent treatment strategies, nearly always including niacin.

Additionally, individual responses to daily niacin, while mostly evident after a month at effective doses, tends to continue to slowly improve further over time. However, careful patient understanding of how to achieve this without nuisance symptoms is needed, though not often achieved. Tapeworms în ficat changes to achieve benefit have been more controversial, generally far less effective and less widely adhered to with success.

Cell structure relies on fat membranes to separate and organize intracellular water, proteins and nucleic acids and cholesterol is one of the components of all animal cell membranes. Caldwell B Esselstyn Jr. While the absolute production quantities vary with the individual, group averages for total human body content of cholesterol within the U. For many, especially those with greater than optimal body mass and increased glucose levels, reducing carbohydrate especially simple forms intake, not fats or cholesterol, is often more effective for improving lipoprotein expression patterns, weight and blood glucose values.

However, evidence has increased that processed, particularly industrial non-enzymatic. There is also a variety of evidence, though less robust, that homocysteine and uric acid levels, including within the normal range promote atherosclerosis and that lowering these levels is helpful, up to a point.

In animals Vitamin C deficiency has been confirmed as an important role in development of hypercholesterolemia and atherosclerosis, but due to ethical reasons placebo-controlled human studies are impossible to do. Vitamin C acts as an antioxidant in vessels and inhibits inflammatory process. It has therapeutic properties on high blood pressure and its Tapeworms în ficat, and arterial stiffness in diabetes.

The scale of vitamin C benefits on cardiovascular system led several authors to the Tapeworms în ficat, that vitamin C deficiency is the primary cause of cardiovascular diseases.

The theory was unified by twice Nobel prize winner Linus Pauling and Matthias Rath. They suggest, that clinical manifestations of cardiovascular diseases are merely overshoot of body defense mechanisms, that are involved in stabilisation of vascular wall, after it is weakened by the vitamin C deficiency and the subsequent collagen degradation.

They discuss several metabolic and genetic predispositions and their pathomechanism. Trials on Vitamin E have been done, but they have failed to find a beneficial effect, for various reasons, but for some patients at high risk for atherosclerosis there may be some benefits. It has been suggested that excess iron may be involved in development of atherosclerosis, but one study found reducing body iron stores in patients with symptomatic peripheral artery disease through phlebotomy did not significantly decrease all-cause mortality or death plus nonfatal myocardial infarction and evebyq.b0ne.comr studies may be warranted.

Surgical intervention Other physical Tapeworms în ficat, helpful in the short term, include minimally invasive angioplasty procedures that may include stents to physically expand narrowed arteries and major invasive surgery, such as bypass surgery, Tapeworms în ficat create additional blood supply connections that go around the more severely narrowed Tapeworms în ficat. Prophylaxis Patients at risk for atherosclerosis-related diseases are increasingly being treated prophylactically with low-dose aspirin and a statin.

The high incidence of cardiovascular disease led Wald and Law to propose a Polypill, a once-daily pill containing these two types of drugs in addition to an ACE inhibitor, diuretic, beta blocker, and folic acid.

It must be emphasized however that this is purely theoretical, as the Polypill has never been tested in a clinical trial.

Medical treatments often focus predominantly on the symptoms. However, over time, the treatments which focus on decreasing the underlying atherosclerosis processes, as opposed to simply treating the symptoms resulting from the atherosclerosis, have been shown by clinical trials to be more effective.

In summary, the key to the more effective approaches has been better understanding of the widespread and insidious nature of the disease and to combine multiple different treatment strategies, not rely on one or a few approaches. In addition, for those approaches, such as lipoprotein transport behaviors, which have been shown to produce the most success, adopting more Tapeworms în ficat combination treatment strategies has generally produced better results, both before and especially after people are symptomatic.

Because many blood thinners, particularly salicylates such as warfarin and aspirin thin the blood by interfering with Vitamin K, there is recent evidence that blood thinners which work by this mechanism, can actually worsen arterial calcification in the long term even though they thin the blood in the short term.

Methods to increase high-density lipoprotein HDL particle concentrations, which in some animal studies largely reverses and remove atheromas, are being developed and researched. However most individuals have nuisance symptoms with short term flushing reactions, especially initially, and so working with a physician with a history of successful experience with niacin implementation, careful selection of brand, dosing strategy, etc.

However, increasing HDL by any means is not necessarily helpful. The actions of macrophages drive atherosclerotic plaque progression. Immunomodulation of atherosclerosis is the Tapeworms în ficat for techniques which modulate immune system function in order to suppress this macrophage action. Research on genetic expression and control mechanisms is progressing. Some controversial research has suggested a link between atherosclerosis and the presence of several different nanobacteria in the arteries, e.

The immunomodulation approaches mentioned above, because they deal with innate responses of the host to promote atherosclerosis, have far greater prospects for success. The National Heart, Lung, and Blood Institute NHLBI and National Center for Complementary and Alternative Medicine NCCAM sponsored The Trial to Assess Chelation Therapy TACT. The purpose of this study is to determine the safety and effectiveness of ethylene diamine tetra-acetic EDTA chelation therapy in individuals with coronary artery disease.

EDTA chelation therapy involves repeated administrations of a synthetic amino acid to reduce atherosclerotic plaque and other mineral deposits throughout the cardiovascular system. The results of TACT will provide either a significant positive result or an informative null result upon which rational clinical decision-making and health policy can be based.

The Hemorheologic-Hemodynamic Theory The theory of atherogenesis described above is presented largely as fact. While representing the mainstream view, this theory has several weaknesses. Aggressive reduction of serum LDL-cholesterol using high dose statin therapy still leaves significant risk of adverse cardiovascular events in high-risk patients. This, in conjunction with the failure of torcetrapib in clinical trials, should prompt reexamination of mainstream atherogenesis theory.

Further, oxidized LDL is widely distributed in both arteries and veins, the latter of which do not develop atherosclerosis. The distribution of the putative precursor lesion, the fatty streak, correlates poorly with the distribution of fibrous plaques. The mainstream theory of atherogenesis does not explain the localization of fibrous plaques to the vicinity of changing arterial geometry, such as branches, curves, and dilatations.

Mainstream theory provides no explanation for accelerated atherosclerosis associated with hypertension. Finally, mainstream theory cannot explain the presence of fibrous plaques in synthetic arteriovenous grafts. The hemorheologic—hemodynamic theory holds that atherosclerosis is a disease of stasis of blood, which bay vierme the organization of a thrombus into an atherosclerotic of blood predisposes to thrombosis, as described in Virchow's triad.

Risk factors for atherosclerosis create larger areas of decreased shear flow by increasing blood viscosity, arterial stiffness, or both. Both of these abnormalities are seen in association with aging, hypertension, diabetes mellitus, cigarette smoking, and obesity. The theory posits that the same pathologic process, thrombosis, leads to both plaque development and its complication, superimposed thrombosis and infarction.

The name reflects the fact that the interaction of hemorheologic, i. Viscosity and localized stasis In arteries during systole, there is a gradient of blood velocity with the highest velocity in the center of the vessel and the lowest against the arterial wall.

In areas of vascular branching, curving and dilatation, focal blood pooling occurs in the low shear environment against the arterial wall if blood velocity exceeds a critical value of Reynolds number see below.

This phenomenon is seen in nature when rapidly flowing water encounters an obstruction, forming eddies and pools. Blood is a non-Newtonian fluid, and its viscosity progressively increases with decreasing shear. In areas of pooling, a vicious cycle can Tapeworms în ficat in which increased viscosity Tapeworms în ficat to decreased flow, further increasing viscosity and decreasing flow, leading read article to stasis and thrombosis in the absence of adequate fibrinolytic activity.

Decreased blood flow promotes thrombosis by decreasing influx of fibrinolytic molecules and decreasing efflux of activated clotting factors. Platelets activated by high shear in the central column of blood can be directed to the vicinity of the arterial wall by eddy currents.

In these areas, decreased blood flow decreases endothelial production of molecules with antithrombotic activity such as nitric oxide and prostacyclin, further promoting thrombosis. This is akin to endothelial de semn corpul în un viermi which in mainstream atherogensis theory is thought to be caused by putative cytopathic effects of oxidized lowdensity lipoprotein.

Arterial Tapeworms în ficat Increased arterial stiffness accelerates atherosclerosis by increasing peak arterial blood velocity, thereby increasing Reynold's number, which indicates the propensity for a flowing fluid to develop pools and eddy currents in association with changing arterial geometry. In the normally compliant aorta, a portion of each stroke volume is stored in systole and propelled with lower velocity in diastole, creating blood flow throughout most of the cardiac cycle.

An area of pooling created by high velocity would disappear during slow diastolic flow, and any accumulated microthrombus would be dispersed. In a perfectly stiff aorta, the entire pentru viermi la pisici kanikvantel de tablete volume would be expelled in systole.

Given constant stroke volume, conservation of mass requires increasing peak arterial blood velocity with increasing arterial stiffness. This will allow the time necessary for thrombus growth and subsequent organization see below.

Additionally, increased peak arterial velocity will augment shear-mediated platelet activiation. Organization of mural thrombi J. Arterial thrombi tend to remain localized to the low shear environment of the arterial wall because of high blood velocity in the central portion of the artery. These Tapeworms în ficat are know as "mural" or "parietal. Thus, thrombi in veins are more likely to become occlusive, as in deep venous thrombosis. This is why atherosclerosis is limited to arteries.

If thrombi persist, whether in arteries or veins, they undergo organization, in which circulating fibrocytes colonize the thrombus and. Role of lipoproteins in atherogenesis The hemorheologic-hemodynamic theory predicts that low-density lipoprotein LDL should increase blood viscosity and high-density liporotein HDL should decrease Tapeworms în ficat viscosity, which has been demonstrated experimentally.

Erythrocyte aggregates increase blood viscosity at low shear by increasing the inertia of the suspended particles. Instead, by competing with LDL for binding to erythrocytes, it antagonizes erythrocyte aggregation and decreases blood viscosity. Erythrocyte aggregates are weak, and progressively distrupted with increasing shear. Given the relationship of LDL to blood viscosity, it Tapeworms în ficat not surprising that hypercholesterolemia is a risk factor for both atherosclerosis and deep venous thrombosis.

The hemorheologic-hemodynamic theory explains the significant remaining risk of adverse cardiovascular events in patients with established coronary artery disease despite aggressive lowering of LDL-cholesterol using high dose statin therapy. Such therapy does not address the adverse consequences of arterial stiffening, or increased blood viscosity caused by other factors. The hemorheologic-hemodynamic theory explains the existence of atherosclerotic plaques in synthetic arteriovenous grafts.

These provide an extreme hemodynamic environment, where extremely high velocity Tapeworms în ficat flows through a curved vessel. These vessels are prone to thrombosis and development of atherosclerotic plaques despite anticoagulation.

These vessels lack a tunica media, which received wisdom maintains is the origin of smooth muscle cells in atherosclerotic plaques via migration. The identification of the fibrocyte provides an alternative explanation for the origin of smooth muscle cells in atherosclerotic plaques.

Being largely inanimate, the capacity of these vessels to respond to an injury with an inflammatory response, the inciting cause of atherosclerosis according to mainstream atherogenesis theory, would be very limited. Further, this theory explains the benefit of blood donation and drinking large quantities of water. Both of these very low risk interventions reduce blood viscosity. The hemorheologic-hemodynamic eliminates reliance on the fatty streak in atherogenesis.

Tapeworms în ficat streaks routinely resolve without Copiii de la viermi de la 1 an. Tapeworms în ficat is acknowledged in by mainstream atherogenesis theory, which is unable to predict why a particular fatty streak progresses into an atherosclerotic plaque while the majority regress.

Increased HDL particle size and increased low-shear blood viscosity caused by torcetrapib therapy could account for the increased cardiovascular mortality seen in clinical trials. Increased peak arterial blood velocity and arterial stiffening may also play a role in sudden cardiac death associated with physical exertion.

Physical exertion results in increased cardiac Tapeworms în ficat and increased blood pressure, both of which could increase peak arterial velocity, although the effect of increased cardiac output on Tapeworms în ficat arterial blood velocity in this situation has not been studied. Increased Reynolds number could lead to vierme modul de a trata oxiuroza Tapeworms în ficat thrombosis as described above.

The future Validation of the hemorheologic-hemodynamic theory will require a prospective study to determine if measuring blood viscosity and peak arterial blood velocity identifies subjects at high risk for symptomatic atherosclerosis better than routine markers such as lipid analysis.
