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. [1]
Calcium. Plaque build-up often doesn’t cause symptoms, but it can block blood flow to vital organs like your heart. ... Coronary calcium scan, a type of CT scan that measures calcium build-up in ...
ICD-10 coding number Diseases Database coding number Medical Subject Headings Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state ...
Plaque is made up of fat, cholesterol, immune cells, calcium, and other substances found in the blood. [10] [9] The narrowing of arteries limits the flow of oxygen-rich blood to parts of the body. [10] Diagnosis is based upon a physical exam, electrocardiogram, and exercise stress test, among others. [13]
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]
Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease, and heart attacks. [4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [5]
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 ...
Previously, unstable angina was assumed to be angina pectoris caused by disruption of an atherosclerotic plaque with partial thrombosis and possibly embolization or vasospasm leading to myocardial ischemia. [9] [10] However, sensitive troponin assays reveal rise of cardiac troponin in the bloodstream with episodes of even mild myocardial ...
