Vulnerable plaque vs stable plaque [ edit ] The factors involved to promote either a vulnerable plaque or a stable plaque are not clear yet, however, the major differences between a vulnerable and stable plaque are that vulnerable plaques have a ''rich-lipid core'' and a ''thin fibrous cap'' in comparison with the ''thick fibrous cap'' and the ...
Atherosclerotic lesions, or atherosclerotic plaques, are separated into two broad categories: Stable and unstable (also called vulnerable). [79] The pathobiology of atherosclerotic lesions is very complicated, but generally, stable atherosclerotic plaques, which tend to be asymptomatic, are rich in extracellular matrix and smooth muscle cells.
In stable angina, the developing atheroma (a fatty plaque) is protected with a fibrous cap. This cap may rupture in unstable angina, allowing blood clots to precipitate and further decrease the area of the coronary vessel's lumen or the interior open space within an artery. This explains why, in many cases, unstable angina develops ...
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 ...
In contrast with stable angina, unstable angina occurs suddenly, often at rest or with minimal exertion, or at lesser degrees of exertion than the individual's previous angina ("crescendo angina"). New-onset angina is also considered unstable angina, since it suggests a new problem in a coronary artery. [8]
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.
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.
Stable flies tend to swarm closer to the ground, near ankle-level, earning them the occasional nickname "ankle biters." More: Michigan garden bugs: How to get rid of beetles, grubs, more (freep.com)
