To assess the genetics of hyperlipidemia in coronary heart disease, family studies were carried out in 2520 relatives and spouses of 176 survivors of myocardial infarction, including 149 hyperlipidemic and 27 normolipidemic individuals. The distribution of fasting plasma cholesterol and triglyceride values in relatives, together with segregation analyses, suggested the presence of five distinct lipid disorders. Three of these-familial hypercholesterolemia, familial hypertriglyceridemia, and familial combined hyperlipidemia -appeared to represent dominant expression of three different autosomal genes, occurring in about 20% of survivors below 60 yr of age and 7 % of all older survivors. Two other disorders-polygenic hypercholesterolemia and sporadic hypertriglyceridemiaeach affected about 6% of survivors in both age groups.This work was presented in part at

The pleiotropic effects of statins do not seem to contribute an additional cardiovascular risk reduction benefit beyond that expected from the degree of LDL-C lowering observed in other trials that primarily lowered LDL-C.

Lower rates of CHD events among women in the hormone group in the final years of HERS did not persist during additional years of follow-up. After 6.8 years, hormone therapy did not reduce risk of cardiovascular events in women with CHD. Postmenopausal hormone therapy should not be used to reduce risk for CHD events in women with CHD.

Most patients with CVD in primary care were not receiving cholesterol screening and management as recommended by the National Cholesterol Education Program guidelines in the 2 years after their release. Increasing cholesterol screening and treatment should be a priority for practice quality improvement and could result in significant reductions in CVD events for high-risk patients.
