摘要

Background

HMG-CoA reductase inhibitors (statins) are known to have pleiotropic effects in addition to their lipid-lowering effect. Many studies have suggested cardioprotective effects of statins, however, recent large-scale clinical trials using rosuvastatin, a hydrophilic statin, have failed to show beneficial effects on cardiovascular events in patients with severe heart failure. We have designed the study to evaluate the effects of pitavastatin, a lipophilic statin, on Japanese patients with mild to moderate heart failure.

Methods and results

Five hundred seventy-seven patients with chronic heart failure were enrolled. We used a prospective, randomized, open-label, and blinded-endpoint evaluation (PROBE) design. Patients aged 20-79 years old with symptomatic (NYHA functional class II or III) heart failure and a left ventricular ejection fraction of 鈮?#xA0;45%were randomly allocated to either receive pitavastatin (2 mg/day) or not in addition to conventional therapy for heart failure by using the minimization method. Follow-up will be continued until March 2011. The primary endpoint is a composite of cardiac death and hospitalization for worsening heart failure.

Conclusions

The PEARL study will provide important data on the role of pitavastatin in the treatment of Japanese patients with mildly symptomatic heart failure (UMIN-ID: UMINC000000428).
