Abstract

Abstract: Background and aims: Little is known about the relation between serum lipid parameters and serial change in plaque composition using in vivo coronary imaging. The aim of this study was to examine the association between serum lipids and change in coronary plaque lipid burden assessed by near-infrared spectroscopy (NIRS). Methods: We performed serial NIRS-intravascular ultrasound studies in 49 patients who underwent coronary angiography for an acute coronary syndrome (ACS) or stable ischemic symptoms. Univariable and multivariable linear regression analyses were applied to evaluate the relationship between serum lipid parameters and change in lipid core burden index at the 4-mm maximal segment (max LCBI4mm ). Results: Mean patient age was 61 ± 9 y, 29% were women, 35% had an ACS clinical presentation, 78% received statin therapy at baseline, and median low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), total cholesterol and triglyceride levels were 101, 43, 174 and 133 mg/dL, respectively. During a median follow-up period of 13 months, max LCBI4mm significantly decreased from 277 to 194 ( p = 0.001). On univariable analysis, the percent change in HDL-C negatively associated with the change in max LCBI4mm (β = −3.19, p = 0.004). There were no significant associations between the other lipid parameters and change in max LCBI4mm . On multivariable analysis, percent change in HDL-C remained significantly associated with the change in max LCBI4mm ( p = 0.002). Conclusions: Change in HDL-C, but not other lipids parameters, associated with changes in coronary plaque lipid burden assessed by NIRS. These findings highlight the potential therapeutic importance of high-density lipoprotein on serial change in plaque composition. Highlights: Change in HDL-C inversely correlates with change in coronary lipid burden. No association with other lipid parameters. This highlights the potential importance of raising HDL-C.
