摘要

The most dramatic development in the past year in the lipid-lipoprotein field was the virtual collapse of HDL as both a direct causal factor in atherosclerosis and as a target for therapy. Although plasma HDL cholesterol concentration remains both a superior risk predictor and an essential component of patient diagnosis and risk stratification, the central role of HDL in atherosclerosis has been undermined by recent publications of two types of studies. First, epidemiological scale Mendelian randomization studies of both common and rare genetic variants that alter HDL cholesterol concentration -presumably over a lifetime - show no relationship with clinical atherosclerotic events [1-4]. In contrast, analogous variants that affect plasma LDL cholesterol concentration show strong and consistent relationships with cardiovascular outcomes.
