Association of high-density lipoprotein cholesterol with coronary heart disease risk across categories of low-density lipoprotein cholesterol: the atherosclerosis risk in communities study.

INTRODUCTION: National cholesterol treatment guidelines include a low level of high-density lipoprotein (HDL) cholesterol (

METHODS: We investigated the association of HDL and LDL-cholesterol with incident CHD events (fatal or nonfatal CHD) over 14 years of follow-up among 13,615 adults aged 45 to 64 years in the Atherosclerosis Risk in Communities study.

RESULTS: A total of 966 (7.1%) participants had a CHD event during follow-up. After adjustment for age, race, sex, diabetes, smoking, alcohol consumption, systolic blood pressure, waist circumference, chronic kidney disease and physical activity, a graded association was present between progressively lower levels of HDL-cholesterol and higher CHD risk, overall (P

CONCLUSIONS: These data suggest a graded association exists between lower levels of HDL-cholesterol and CHD across the full range of LDL-cholesterol levels. As interventions targeting HDL levels are developed, the combinatorial effects of lower HDL levels with various levels of LDL-cholesterol should be examined.
