CARDIOL.. 27(3):325-33, 2014 Jun.Abstract: OBJECTIVES: This study utilized grayscale intravascular ultrasound (IVUS) to explore the relationship between high-density lipoprotein cholesterol (HDL-C) levels and culprit lesion characteristics in patients with coronary artery disease.Abstract: BACKGROUND: Low HDL-C is associated with an increased risk of cardiovascular events. Previous IVUS studies have suggested a significant association between lesion characteristics and cardiovascular events.Abstract: METHODS: According to HDL-C levels, 120 patients who underwent IVUS for native, de novo coronary lesions before any intervention were divided into a low HDL-C group (<40mg/dL, n=60) and a high HDL-C group (>40mg/dL, n=60). Quantitative and qualitative IVUS analyses were performed to compare lesion characteristics.Abstract: RESULTS: Quantitative IVUS measurements showed no significant differences between the 2 groups. HDL-C level was not significantly correlated with remodeling index (r=0.03, P=0.78). However, attenuated plaque was more frequent in the low HDL-C group (48.3% vs. 28.3%, P=0.02) and a greater percentage of attenuated plaque was found in this group (32.5+/-21.3% vs. 21.0+/-11.0%, P=0.02). Moreover, when categorized into 4 groups according to HDL-C levels, the proportion of attenuated plaque (64.7% in group with <30mg/dL, 41.9% in group with 30-39mg/dL, 36.4% in group with 40-59mg/dL, and 6.3% in group with >60mg/dL; P=0.001 for trend) was significantly different among groups. On multivariate analysis, only HDL-C and male gender were independently associated with the presence of attenuated plaque at the culprit lesions.Abstract: CONCLUSIONS: Patients with low levels of HDL-C may be at increased risk of having a higher incidence of attenuated plaques.Copyright © 2014, Wiley Periodicals, Inc.
