Effects of statin treatment in men and women with stable coronary heart disease: a subgroup analysis of the GREACE Study

ABSTRACT

Background: Reducing low-density lipoprotein cholesterol (LDL-C) levels to National Cholesterol Expert Panel (NCEP) goal is recommended. However, sex-specific effects may influence benefit.

Methods and results: In this post hoc analysis of the GREek Atorvastatin and Coronary heart disease (CHD) Evaluation [GREACE] study we investigated the extent in vascular event reduction by statin treatment according to sex. From a total of 1600 patients with stable CHD, 624/176 and 632/168 were men/women on atorvastatin or on usual care, respectively. During 3-year follow-up, comparison of atorvastatin treatment with usual care demonstrated a relative risk reduction (RRR) of the primary end point (all vascular events) of 54?%?in women (hazard ratio [HR] 0.46, 95?%?confidence interval [CI] 0.24–0.87, p?=?0.003) and of 50?%?in men (HR 0.50, 95?%?CI 0.32–0.70, p?Conclusions: Treatment with atorvastatin to the NCEP LDL-C goal compared with “usual care” significantly reduced CHD morbidity and mortality in both men and women. Both men and women benefited from statin treatment possibly with different mechanisms making a contribution over and above LDL-C reduction.
