Abstract

Non-high-density lipoprotein cholesterol (non-HDLc) is an independent predictor of cardiovascular disease risk, with elevated levels signifying an increased risk beyond low-density lipoprotein. Previous data have shown inconsistent association of lipid subfractions with progression of coronary artery calcium (CAC), a surrogate marker of incident cardiovascular disease. We sought to evaluate the association between non-HDLc and development (incident) and progression of CAC in a cohort of multiethnic asymptomatic subjects. The cohort (n = 5,705) was derived from the limited access data set of the Multi-Ethnic Study of Atherosclerosis obtained from the National Heart Lung and Blood Institute. Multivariable regression analysis was performed to derive the association between non-HDLc and incident CAC (n = 2,927) and non-HDLc and progression of CAC (n = 2,778). In the population without CAC at baseline, non-HDLc, especially >190 mg/dl, was independently associated with incident CAC (relative risk 1.40, 95% confidence interval 1.09 to 1.79, p = 0.008) after adjustments with age, gender, race, systolic blood pressure, antihypertension medication use, smoking, diabetes, lipid-lowering therapy use, follow-up duration, and waist-hip ratio. Similarly, among those with CAC at baseline, non-HDLc levels >190 mg/dl were associated with significant CAC progression in the overall population (β 16.4, 95% confidence interval -5.63 to 27.2, p = 0.003) after adjustments. In conclusion, non-HDLc levels, especially >190 mg/dl, are consistently associated with increased risk of CAC progression. Our results suggest that among lipid fractions, non-HDLc may be best suited for the prediction of future CAC progression.
