Biology:Fibrous cap
From HandWiki
Short description: Layer found in atheromatous plaques
The fibrous cap is a layer of fibrous connective tissue, which is thicker and less cellular than the normal intima, found in atheromatous plaques. The fibrous cap contains macrophages and smooth muscle cells.[1] The fibrous cap of an atheroma is composed of bundles of muscle cells, macrophages, foam cells, lymphocytes, collagen and elastin.[1] An atheroma with a cap is termed a fibrous cap atheroma.
Rupture
The rupture of a fibrous cap can lead to a stroke, or a heart attack either of which has the potential to be fatal.[2] The fibrous cap is prone to rupture and ulceration which can lead to thrombosis. In advanced lesions, further complications may arise including calcification of the fibrous cap.[3]
