Abstract

Aim: Diabetic patients with coronary artery disease have a high incidence of cardiovascular events, which was associated with increased coronary plaque volume. Low-density lipoprotein cholesterol (LDL-C) and blood pressure (BP) play pivotal roles in the progression of coronary plaque. Several trials have shown that intervention for a single risk factor reduced the development of coronary plaque progression. However, it remained uncertain whether total risk management for LDL-C, BP, and glycosylated Hb (HbA1c) has a beneficial effect on coronary plaque volume in diabetic patients. Methods: This study was a sub-study of the JAPAN-ACS that was a prospective, randomized, openlabel trial that evaluated the impact of intensive lipid-lowering therapy on coronary plaque volume in patients with acute coronary syndrome (ACS). Among a total of 252 patients, 73 diabetic patients were analyzed. We examined the impact of total risk management (LDL-C <80 mg/dL, systolic BP <130 mmHg, and HbA1c <6.5%) on changes in coronary plaque volume. The patients were divided into four groups according to the number of risk factors that achieved the target value. Results: Baseline characteristics were similar among the groups. The degree of coronary plaque regression was greater in patients who achieved total risk management. The number of risk factors that achieved the target level was associated with the extent of the coronary plaque volume reduction in a dose-dependent manner. Conclusion: Total risk management that focused on LDL-C, BP, and HbA1c had a beneficial impact on the coronary plaque regression in diabetic patients with ACS.
