title: Lipoproteins and apolipoproteins in young male survivors of myocardial infarction.
abstract: Plasma and lipoprotein cholesterol, triglycerides, apolipoproteins (apo) A-I, A-II, B and phospholipid concentrations were measured at 10 days and 4 months after myocardial infarction (MI) in 60 young Kuwaiti male MI survivors below the age of 40 years. Controls were matched for age, relative weights, smoking, dietary habits and physical activities. The young MI survivors had significantly higher levels of total and LDL-cholesterol, and ratios of LDL/HDL- and LDL/HDL2-cholesterol. Total VLDL and LDL triglycerides, and phospholipids were also elevated in MI survivors compared to controls. Similarly, plasma and LDL-apo B as well as the ratios of apo B/apo A-I were higher in the MI group. There was no significant change in the levels of VLDL and HDL3-cholesterol and of apo A-II in these patients compared to their controls. Concentrations of HDL- and HDL2-cholesterol and of plasma and HDL apo A-I were significantly lower in the young MI survivors compared to the control subjects. The better discriminating lipoproteins and apolipoproteins in MI patients in descending order were HDL2-cholesterol greater than apo B greater than apo A-I greater than VLDL-triglyceride greater than HDL-cholesterol greater than LDL/HDL2-cholesterol greater than triglycerides. The data indicate that measurement of HDL2-cholesterol, apo B and apo A-I may be useful indicators in assessing coronary artery disease risk than triglycerides (TG), total cholesterol (TC), LDL-cholesterol and HDL-cholesterol.
