Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the primary preventive effect of low-dose pravastatin against coronary heart disease (CHD) in Japanese hypercholesterolemic patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

MEGA Study is the first prospective, randomized, controlled trial conducted in Japan to evaluate the primary preventive effect of pravastatin against CHD in daily clinical practice. Because the dose of pravastatin used in the MEGA Study was 10-20 mg/day, which is consistent with the approved doses in Japan and lower than the doses used in previous large-scale clinical trials.
