Cholesterol efflux capacity (CEC) is inversely associated with CAD risk.
The CETP inhibitor TA-8995 increases total, abca1 and non-ABCA1 CEC.
TA-8995 increases pre-Beta1 HDL particles, the main acceptor for ABCA1 CEC.
Total CEC increase was associated with pre-Beta1 increase but not with HDL-C increase.
