Atherosclerosis (atherosclerosis) is common and most important one kind in genus of stiff vessel diseases, disease
Change takes place mostly in sustainer, coronary artery and cerebral artery, and the arteria renalis and mesenteric artery also have generation.Its pathological change is tired out
And under arterial vascular inner membrance, inner membrance and middle level.Diseased region has lipid accumulation, and invades iuntercellular under intracellular or inner membrance
Gap, cause smooth muscle cell and connective tissue proliferation, bleeding, thrombosis and calcinosis.Due to the inside and outside lipid product of cell
It is poly- obvious, it is athero- in yellow in the lipid outward appearance of endarterium, therefore turn into atherosclerosis.The dynamic of atherosis occurs
Vascular wall thickening is hardened, and elasticity weakens, and tube chamber reduces, and ischemic lesions can occur for institute's dominating organs.
The pathogenesis of atherosclerosis not yet illustrates completely, but has proven to the lipid in atheromatous plaque and be mainly derived from
Blood plasma.Thus, it is considered that this sick generation and disorders of lipid metabolism and hyperlipemia relation are very close.Blood fat includes courage
The non-water soluble substances such as sterol, triglycerides and phosphatide, these materials are combined into compound-lipoprotein with apolipoprotein.Fat egg
Blood plasma is dissolved in vain, and whole body is transported to blood circulation.
According to the difference of density, the lipoprotein in human plasma can be divided into four kinds of main Types, i.e., chylomicron (CM),
VLDL (VLDL), low-density lipoprotein (LDL), HDL (HDL).Human body hyperlipemia, mainly
It is that VLDL and LDL increase in blood plasma, immerses arterial wall, cause atherosclerosis.
