Treatment of Hyperlipidemia in Women

Abstract

To assess the evidence that lipid lowering prevents coronary heart disease (CHD) events in women. English-language literature assessing the effects of cholesterol lowering with dietary and/or drug interventions as primary or secondary prevention on CHD events in women. Coronary heart disease and total mortality were the primary outcomes assessed. Angiographic regression of coronary atherosclerosis was a secondary outcome. STUDY SELECTION, DATA EXTRACTION, AND DATA SYNTHESIS: All nine of the identified studies that met the criteria were included. Relative risks for CHD and total mortality were calculated from available data. Summary relative risks were calculated using meta-analytic techniques. There is no evidence from primary prevention trials that cholesterol lowering affects total mortality in healthy women, although the available data are limited. Limited evidence suggests that treatment of hypercholesterolemia in women with coronary disease may decrease CHD mortality. Future research should address the role of dietary and other nondrug treatment of hypercholesterolemia in women at high risk for CHD.
