Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm. [ 1 ] With aging, the ascending portion of the thoracic aorta increases in length by approximately 12% per decade, whereas the diameter increases by just 3% per decade.
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
An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall. [ 1 ] [ 2 ] The material consists of mostly macrophage cells , [ 3 ] [ 4 ] or debris, containing lipids , calcium and a variable amount of fibrous connective tissue .
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.
The result is the formation of a thrombus (blood clot) overlying the atheroma, which obstructs blood flow acutely. With the obstruction of blood flow, downstream tissues are starved of oxygen and nutrients. If this is the myocardium (heart muscle) angina (cardiac chest pain) or myocardial infarction (heart attack) develops. [citation needed]
In CAD, atheromatous plaque formation in a coronary artery limits oxygen supply to cardiomyocytes, impairing heart contractility. CAD severity varies based on the extent of coronary artery occlusion. At 75% luminal narrowing, patients experience symptoms associated with limited perfusion of cardiomyocytes, [ 11 ] especially under strenuous ...
