Plaque build-up often doesn’t cause symptoms, but it can block blood flow to vital organs like your heart. Coronary artery disease occurs when atherosclerosis affects the arteries supplying ...
WS patients develop a considerable burden of atherosclerotic plaques in their coronary arteries and aorta: calcification of the aortic valve is also frequently observed. [138] These findings link excessive unrepaired DNA damage to premature aging and early atherosclerotic plaque development (see DNA damage theory of aging). [citation needed]
Find out why coronary calcification is bad for heart health and how to know ... Soft plaque is the most dangerous type of plaque because it can rupture suddenly, leading to blood clots and, in ...
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, 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 ...
A vulnerable plaque is a kind of atheromatous plaque – a collection of white blood cells (primarily macrophages) and lipids (including cholesterol) in the wall of an artery – that is particularly unstable and prone to produce sudden major problems such as a heart attack or stroke.
Monckeberg's calcification typically occurs near the internal elastic lamina or, less frequently, in the media of muscular arteries without alterations in calcium metabolism. Its clinical importance is not yet fully understood. Some recent studies suggest a connection between Monckeberg's calcification and metabolic vascular calcification.
To more accurately determine the severity of stenosis, interventional cardiologists may also employ intravascular ultrasound, which can determine the severity and provide information on the composition of the atheromatous plaque. With the technique of fractional flow reserve, the pressure after the stenosis is compared to mean aortic pressure ...
