- Abstract
The aim of the study was to elucidate the aggressive reduction of both low-density lipoprotein cholesterol (LDL-C) and blood pressure (BP) reduced coronary atherosclerotic plaque volume compared with a standard treatment of LDL-C and BP in Japanese patients with coronary artery disease (CAD). This study is a prospective, randomized, and open-labelled with a blind-endpoint evaluation study. A total of 97 patients (81 men, mean age 62.0 ± 9.6) with CAD undergoing intravascular ultrasonography (IVUS)-guided percutaneous coronary intervention (PCI) were randomized, and 68 patients had IVUS examinations at baseline and at 18-24 months follow-up. Patients were randomly assigned to standard or aggressive strategies targeting LDL-C and a BP of 100 mg/dL and 140/90 mmHg vs. 70 mg/dL and 120/70 mmHg, respectively. The primary endpoint was the percent change in coronary plaque volume. Both standard and aggressive strategies succeeded to achieve target levels of LDL-C and BP; 74.9 ± 14.7 vs. 63.7 ± 11.9 mg/dL (NS) and 124.1 ± 9.4/75.8 ± 7.7 vs. 113.6 ± 9.6/65.8 ± 9.4 mmHg (systolic BP; NS, diastolic BP; p < 0.05), respectively. Both groups showed a significant reduction in the coronary plaque volume of −9.4 ± 10.7% and −8.7 ± 8.6% (NS) in standard and aggressive therapies, respectively. Both standard and aggressive intervention significantly regressed coronary plaque volume by the same degree, suggesting the importance of simultaneous reductions of LDL-C and BP for prevention of CAD.
