A heart attack occurs suddenly when an atherosclerotic plaque in one of the arteries to your heart ruptures. It can cause symptoms such as: Chest pain, pressure, or tightness
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 artery wall. Beneath the endothelium, there is a "fibrous cap" covering the atheromatous "core" of the plaque.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
Coronary endarterectomy involves removing atheroma from the wall of blocked blood vessels (coronary) supplying the heart muscle. The concept was first introduced by Bailey [2] in the 1950s prior to the advent of coronary artery bypass surgery to help patients with angina and coronary artery disease. It is still used today when coronary artery ...
"Dental plaque is a sticky film of bacteria, while arterial plaque is a complex buildup of cholesterol, fat, calcium and cellular debris on artery walls," explains Dr. Rigved Tadwalkar, MD, a ...
This includes a coronary artery calcium score (a low-dose CAT scan of the heart that looks for calcium deposits in the arteries, which is a sign of plaque buildup), a coronary CTA (an imaging test ...
Arteriosclerosis is any hardening (and loss of elasticity) of medium or large arteries (from the Greek arteria, meaning artery, and sclerosis, meaning hardening) Atherosclerosis is a hardening of an artery specifically due to an atheromatous plaque. The term atherogenic is used for substances or processes that cause atherosclerosis.
With the heart still, the tip of the heart is taken out of pericardium so that native arteries lying on the posterior side of the heart are accessible. Usually, distal anastomoses are constructed first (first to the right coronary system, then to the circumflex) and then the sequential anastomosis if necessary.
