Apolipoprotein A-I Infusions in Coronary Artery Disease: A Systematic Review.

Coronary artery disease (CAD) is the leading cause of death globally. Apolipoprotein A-1 (apoA-1), the primary protein component of high-density lipoprotein (HDL), facilitates reverse cholesterol transport and has emerged as a potential therapeutic target. While pharmacologic efforts to raise HDL-C levels have failed to reduce cardiovascular events, focus has shifted to HDL functionality, particularly cholesterol efflux capacity (CEC). ApoA-1 infusions have demonstrated antiatherogenic effects in preclinical models and early human trials by enhancing CEC and promoting cholesterol clearance. This review summarizes the rationale and evolving clinical trial landscape investigating apoA-1 infusions as a novel therapy for CAD prevention and treatment.
