چکیده انگلیسی


- Cholesterol efflux capacity was inversely associated with risk of all-cause and cardiovascular mortality in both ACS and stable CAD patients, independent of circulating HDL cholesterol level.
- Adding cholesterol efflux capacity to a model containing traditional cardiovascular risk factors significantly increased its discriminatory power and predictive ability for all-cause and cardiovascular mortality.
- Furthermore, our findings reveal that an increase in circulating HDL-C levels does not enhance cholesterol efflux capacity when its level is over 50 mg/dL in patients with CAD.

BackgroundAlthough diminished cholesterol efflux capacity is positively related with prevalent coronary artery disease, its prognostic value for incident cardiovascular events remains a topic of debate. This work aims to investigate the association between cholesterol efflux capacity and all-cause and cardiovascular mortality in patients with coronary artery disease.Methods and ResultsWe measured cholesterol efflux capacity at baseline in 1737 patients with coronary artery disease from the Guangdong Coronary Artery Disease Cohort. During 6645 person-years of follow-up, 166 deaths were registered, 122 of which were caused by cardiovascular diseases. After multivariate adjustment for factors related to cardiovascular diseases, the hazard ratios of cholesterol efflux capacity in the fourth quartile compared with those in the bottom quartile were 0.24 (95% confidence intervals 0.13-0.44) for all-cause mortality (P < 0.001), and 0.17 (95% confidence intervals 0.08-0.39) for cardiovascular mortality (P < 0.001). Adding cholesterol efflux capacity to a model containing traditional cardiovascular risk factors significantly increases its discriminatory power and predictive ability for all-cause (area under receiver operating characteristic curve 0.79 versus 0.76, P = 0.001; net reclassification improvement 14.5%, P = 0.001; integrated discrimination improvement 0.016, P < 0.001) and cardiovascular (area under receiver operating characteristic curve 0.81 versus 0.78, P = 0.001; net reclassification improvement 18.4%, P < 0.001; integrated discrimination improvement 0.015, P < 0.001) death, respectively.ConclusionsCholesterol efflux capacity may serve as an independent measure for predicting all-cause and cardiovascular mortality in patients with coronary artery disease.
