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 ...
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]
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 ...
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.
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]
The primary factor differentiating unstable angina from stable angina (other than symptoms) is the underlying pathophysiology of the atherosclerosis. The pathophysiology of unstable angina is the reduction of coronary blood flow due to transient platelet aggregation on apparently normal endothelium, coronary artery spasms, or coronary thrombosis.
