【 摘 要 】

BACKGROUND Serum cholesterol efflux capacity, a biomarker that integrates contributors and modulators of the initial step of the reverse cholesterol transport, has been associated with atherosclerosis independently of high-density lipoprotein (HDL) cholesterol level. OBJECTIVES The authors evaluated the prognostic impact of serum cholesterol efflux capacity on mortality in a large cohort of patients hospitalized for an acute myocardial infarction (MI). METHODS Serum cholesterol efflux capacity, cholesteryl ester transfer protein (CETP) activity, total cholesterol, lowdensity lipoprotein cholesterol, HDL cholesterol, and triglyceride levels were measured in 1,609 consecutive patients admitted with an acute MI. The primary endpoint was all-cause mortality evaluated at 6 years with a median follow-up of 1.9 years (interquartile range: 1.5 to 4.2 years). An analysis by quartile of serum cholesterol efflux capacity was also performed. RESULTS In a fully adjusted model that included age, sex, traditional cardiovascular risk factors including lipid levels, and prognostic factors of MI, serum cholesterol efflux capacity was a strong predictor of survival (adjusted hazard ratio for mortality per 1-SD increase in serum cholesterol efflux capacity, 0.79; 95% confidence interval: 0.66 to 0.95; p = 0.0132). Patients displaying an elevated serum cholesterol efflux capacity had a marked lower rate of mortality at 6 years (adjusted hazard ratio: 0.54 [0.32 to 0.89]; p = 0.0165) as compared with patients with reduced serum cholesterol efflux capacity. CONCLUSIONS Serum cholesterol efflux capacity, an integrative marker of reverse cholesterol transport pathway and efficacy, was inversely associated with all-cause mortality in MI patients independently of HDL cholesterol level and other risk factors.
