Coronary Artery Disease (Atherosclerosis)

meaning coronary atherosclerosis

Carotid artery disease affects the arteries near the brain in the same way, and affects the blood supply to the limbs. It has been reported that eroded plaques have greater proportion of female, younger age, less % stenosis, less calcification, and less obstructive thrombus as compared with ruptured plaques. Conclusions Atherosclerosis is a chronic and progressive disease that causes substantial cardiovascular morbidity and mortality. Angioplasty involves expanding the artery and opening the blockage so that the blood can flow through properly again. Sometimes is necessary to attach new arteries or veins to go around the blockages. When sufficiently large, the thrombus can either partially or completely occlude the coronary vessel lumen and precipitate an acute coronary event. The major treatment goal is to prevent significant narrowing of the arteries so that symptoms never develop and vital organs are never damaged.

A recent autopsy study in 236 sudden coronary death victims with acute thrombi has reported that the prevalence of calcified nodules was 5%. Those who survive the incident event have substantially higher risk of recurrent coronary events and sudden death, as well as heart failure and stroke. Plaques with small lipid cores, thick fibrous caps, few inflammatory cells and a preponderance of smooth muscle cells are typically stable; conversely, those with large lipid cores, thin fibrous caps, numerous macrophages and relatively few smooth muscle cells are most likely to rupture ,. These techniques can ascertain parameters such as luminal diameter or stenosis, vessel wall thickness, plaque volume, and the specific distribution and localisation of atherosclerotic disease. Considering that red blood cell membranes contain more free cholesterol than any other cells in the body , intraplaque hemorrhage is a logical origin of the free cholesterol seen in advanced necrotic cores.

The necrotic core and the surrounding tissue may be eventually calcified to develop calcified sheets that characterize stable and fibrocalcific plaques. Stable angina is a type of chest pain that is a direct result of poor blood circulation through the arteries. T-lymphocytes and other mediators of inflammation and immunity infiltrate the developing lesion site from both the intimal and adventitial aspects of the vessel wall. A high power image Movat pentachrome stain shows numerous smooth muscle cells within the newly formed proteoglycan-rich neointima black double arrows close to the luminal surface , with clear demarcation from the underlying old collagen-rich fibrous cap. A clinical expert consensus statement by the American College of Cardiology and the American Heart Association suggests that this relatively inexpensive technique may be appropriate for patients at intermediate risk based on their Framingham score, if there is a likelihood that a high coronary artery calcium score may reclassify these patients as higher risk and therefore requiring more intensive treatment. Bone formation is rarely observed in calcified lesions. An understanding of the histomorphological characteristics of coronary plaques is of particular importance for both basic and clinical researchers who investigate the pathogenesis of atherosclerotic coronary disease.

These observations indicate that collections of red blood cells may directly contribute to the necrotic core expansion, plaque enlargement, and lesion instability ,. Cardiac Procedures: Sometimes an is needed to show the blockages and determine whether medications are sufficient for treatment or whether an the use of a balloon to open the blockage and stent a wire mesh tube to keep the artery open are required. You may have to take medication to do this. The prevalence of silent plaque rupture, erosion, or calcified nodule, in the clinical setting remains unknown. If there are high levels of fat and sugar, it could indicate an increased risk of atherosclerosis. Risk Factors Several factors have been identified as potential causes of aortic atherosclerosis.

The major controlled, randomized studies evaluating the capacity of statin therapy to positively impact the progression of atherosclerotic disease are reviewed herein. Coronary heart disease is a clinical manifestation of atherosclerosis, a chronic and progressive inflammatory disease. The process of atherosclerotic plaque progression is considered to be dynamic and complicated. Many researchers have attempted to find out novel biomarkers and obtain detailed plaque morphologies by imaging modalities to predict and prevent this critical complication. Other recent clinical outcome trials , also underscore the considerable need for aggressive lipid lowering with statins in patients with established atherosclerotic disease.

If subclinical atherosclerotic disease is detected, strong consideration should be given to coupling lifestyle modification with statin therapy, irrespective of overall risk factor burden. Native Coronary Artery: is an organ for which a transplant or bypass has been implanted. Aortic atherosclerosis is caused by hardened plaques of cholesterol and fat materials that form on the inside of the border of the aorta. If narrowing is severe, there may be pain at rest, cold toes and feet, pale or bluish skin and hair loss on the legs. Review Criteria Atherosclerotic disease in both its subclinical and clinically established phases is widely prevalent throughout the world.
