At least, in Japanese, it was controversial if lipid-lowering therapy to the patients whose total cholesterol levels <240 mg/dL was needed. Furthermore, in general, a role for early statin therapy in patients with ST-elevated AMI reperfused by primary PCI has not been clearly established. Statins have been shown to prevent coronary artery disease and to preserve left ventricular function in dilated cardiomyopathy. The investigators hypothesized that the early use of statins would reduce cardiovascular events including heart failure in acute myocardial infarction patients. A prospective, randomized, open-label, multicenter trial is conducted in AMI patients with normal total cholesterol levels (180-240 mg/dL). Patients are randomly assigned to receive any available statin within 96 hours of AMI onset or no statin and were followed for up to 24 months. The primary endpoint is a composite of cardiovascular death, nonfatal AMI, recurrent symptomatic myocardial ischemia, congestive heart failure, and stroke.
