Title: PROspective PioglitAzone Clinical Trial In MacroVascular Events: A Macrovascular Outcome Study in Type 2 Diabetic Patients Comparing Pioglitazone With Placebo in Addition to Existing Therapy
Brief Summary: The purpose of this study is to determine whether pioglitazone, once daily (QD), can delay the time to death, heart attack, acute coronary syndrome, heart bypass surgery, stroke, leg bypass surgery or amputation in patients with type 2 diabetes.
