Abstract
The Management of Elevated Cholesterol in the Primary Prevention Group of Adult Japanese (MEGA) Study demonstrated the beneficial effect of low-dose pravastatin treatment (10-20 mg/d) on cardiovascular disease (CVD) in Japanese patients with mild-to-moderate hypercholesterolemia. However, it is not known whether mild lipid modification is effective even for patients at high risk. In this study, we evaluated low-dose pravastatin treatment in patients with metabolic syndrome in the MEGA Study. Metabolic syndrome (MetSyn) was defined according to the modified US National Cholesterol Education Program criteria. There were 72 coronary heart disease (CHD) events and 130 CVD events in 2636 patients with MetSyn, and 70 CHD events and 125 CVD events in 5196 patients without MetSyn (hazard ratios 1.85 and 1.90, respectively). No significant risk reduction in CHD was found in the diet plus pravastatin group compared with the diet group patients with MetSyn (hazard ratio .78, P = .29). On the other hand, there was a significant 36% CVD risk reduction (P = .01) in the diet plus pravastatin group compared with the diet group patients with MetSyn, with a small number needed to treat (45). These results indicate that low-dose pravastatin provi...Continue Reading
