Fibrinoid necrosis is a pathological lesion that affects blood vessels, and is characterized by the occurrence of endothelial damage, followed by leakage of plasma proteins, including fibrinogen, from the vessel lumen; these proteins infiltrate and deposit within the vessel walls, where fibrin polymerization subsequently ensues.
Intravascular ultrasound provides a unique method to study the regression or progression of atherosclerotic lesions in vivo. [2] The progressive accumulation of plaque within the artery wall over decades leads to the development of unstable vulnerable plaque which can detach as clots leading to strokes and heart attacks.
Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart muscle. Without enough blood supply , the heart is unable to work properly, especially under increased stress.
Intravascular imaging is a catheter based system that allows physicians such as interventional cardiologists to acquire images of diseased vessels from inside the artery. . Intravascular imaging provides detailed and accurate measurements of vessel lumen morphology, vessel size, extension of diseased artery segments, vessel size and plaque characteristi
[2] [3] Coronary artery ectasia occurs 4 times more frequently in males than in females and in people who have risk factors for heart disease such as smokers. [1] [4] [5] While the disease is commonly found in patients with atherosclerosis and coronary artery disease, it can occur by itself and in both cases, it can cause health problems.
A vascular anomaly is any of a range of lesions from a simple birthmark to a large tumor that may be disfiguring. They are caused by a disorder of the vascular system. [1] A vascular anomaly is a localized defect in blood vessels or lymph vessels. These defects are characterized by an increased number of vessels, and vessels that are both ...
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
A myocardial infarction, also known as a heart attack, often result in the formation of fibrosis. [2] A myocardial infarction is an ischemic event, or a restriction of blood flow to body tissue, such as by atherothrombosis. [4] Without blood flow to the myocardium, it is deprived of oxygen, causing tissue death and irreversible damage. [5]
