| Outline of Final Research Achievements |
Drug interventions that increase high-density lipoprotein cholesterol (HDL-C), which was thought as “the good cholesterol”, have not reduced cardiovascular events in patients already prescribed statin. These evidences support the importance of HDL functionalities over the simple measurement of HDL-C levels. We demonstrated both cholesterol efflux capacity and anti-oxidant property were better surrogate markers for predicting atherosclerotic cardiovascular disease (ASCVD) than HDL-C levels in patients with familial hypercholesterolemia. Moreover, we investigated the association between cholesterol efflux capacity and incident ASCVD outcomes in a Japanese general population cohort (The Suita study). We found cholesterol efflux capacity was inversely associated with the incidence of all ASCVD events. Further studies are needed to identify the determinants of HDL functionalities. It will lead to develop novel biomarkers and drugs to reduce residual risks after LDL lowering therapy.
