Effect of Aggressive Lipid-Lowering Therapy in Single-Vessel vs. Multivessel Coronary Artery Disease Patients With Acute Coronary Syndrome　― Heart Institute of Japan-Proper Level of Lipid Lowering With Pitavastatin and Ezetimibe in Acute Coronary Syndrome (HIJ-PROPER) Substudy

Background:The effects of aggressive lipid-lowering therapy according to the number of diseased coronary arteries in acute coronary syndrome (ACS) are still controversial. This study investigated the efficacy of this therapy in ACS patients with multivessel disease (MVD) and single-vessel disease (SVD).Methods and Results:The subjects were derived from the HIJ-PROPER study, in which ACS patients with dyslipidemia were randomized to receive either pitavastatin+ezetimibe (targeting low-density lipoprotein cholesterol [LDL-C]
