Yang et al. found that BCAA concentrations are positively associated with the risk factors of coronary artery disease (CAD), e.g., carotid intima-media thickness (cIMT), BMI, blood pressure, fasting blood glucose, TG, apoB, apoB/apoAI ratio, and CRP, and negatively with HDL-C [10]. Here, APOA1 is linked to coronary artery disorder.
