Abstract

Although reduction in total plasma cholesterol has yet to be shown to have a beneficial effect on overall mortality, the weight of experimental and epidemiologic evidence supports efforts to lower total plasma cholesterol levels to reduce the risk of death from coronary heart disease (CHD). This is especially true in patients with heterozygous, type II-A hyperlipoproteinemia, whose total plasma cholesterol levels above the 90th percentile for age and sex place them at markedly increased risk of death from CHD. The lipid results of partial ileal bypass (PIB) were assessed in 110 patients with heterozygous, type II-A hyperlipoproteinemia in the Program on the Surgical Control of the Hyperlipidemias, a randomized, prospective clinical trial assessing the effects of cholesterol reduction on overall mortality and the course of CHD. Compared with dietary control (n = 52), PIB (n = 58) reduced total plasma cholesterol levels 24% +/- 2% (mean +/- SEM), reduced low-density lipoprotein (LDL) cholesterol levels 34% +/- 3%, and increased high-density lipoprotein (HDL) cholesterol levels 5% +/- 5% 5 years after surgery. Very low-density lipoprotein cholesterol levels were 28% +/- 21% higher and plasma triglyceride levels were 24% +/- 11% hi...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
