Vulnerable Plaque

(redirected from Unstable Plaque)
An atheromatous plaque in an arterial wall, which has abundant macrophages, gobs of lipids and cholesterol, and is usually covered by a thin fibrous cap which may rupture. The repeated cycle of rupture and healing is regarded as the major mechanism of arterial stenosis in atherosclerotic heart disease, myocardial infarction and strokes

Once TMAO makes it to the bloodstream, it is involved in changes in whole-body cholesterol metabolism, platelet function and clot formation, vascular inflammation, and unstable plaque formation in artery walls.
The carotid plaque group was further subdivided into stable plaque and unstable plaque subgroups according to plaque characteristics.
In a significant advance, two nutrients have been shown to dramatically slow the worsening of atherosclerotic plaque (by 95%), reduce unstable plaque, and improve endothelial function (by 66%).
That's my guess, that an unstable plaque is reduced to a stable one.
Furthermore, unless there is unstable plaque, it would serve you well to gradually increase exercise so your brain will respond with endothelial growth factor and stimulate formation of collateral blood vessels.
When a small unstable plaque can rapidly rupture and result in total coronary occlusion and when a large plaque can persist for a longer time (or at least when it does not lead to complete occlusion), we can easily see the importance of atherosclerosis velocity.
Pathobiology of acute coronary syndrome involves an unstable plaque with superimposed thrombosis with complete occlusion of artery leading to myocardial infarction.

The presence of more unstable plaque in older men and women may also account for the higher stroke risk.
