  • Title: [Cholesterol and triglycerides in atherosclerosis: epidemiologic and physiopathologic considerations].
    Author: Davidoff P.
    Journal: Rev Med Chil; 1991 Sep; 119(9):1050-8. PubMed ID: 1845100.
    Abstract:
    Increased cholesterol levels above 200 mg/dl, LDL levels above 130 mg/dl and total cholesterol/HDL ratio above 4.5 in males and above 5.0 in females are recognized as indicators of increased risk of atherosclerosis. Risk associated to increased triglyceride levels (above 200 mg/dl) must be judged in relation to associated factors such as family history of coronary heart disease, presence of remnants (type III hyperlipidemia), presence of Lp(a), increased levels of Apo B, reduced levels of HDL2 or Apo A1. VLDL and chylomicron remnants and Lp(a) have an atherogenic power in vitro 2 to 4 times that of LDL. There is a correlation between hypertriglyceridemia and reduced HDL2 and Apo A1 levels. Hypertriglyceridemia is frequently associated to other risk factors like diabetes, obesity, hyperinsulinism, and high blood pressure. Finally, VLDL may elevate levels of plasma plasminogen inhibitor. Thus, hypertriglyceridemia should be investigated when, evaluating risk of atherosclerosis.
