ATP5IF1 and coronary artery disorder: In their most recent research, Genoux et al. measured serum IF1 concentration in 577 males with stable CHD, and found that both cardiovascular and all-cause mortality were lower for patients in the highest quartile of IF1 (hazard ratio [HR] 0.50, 95%CI 0.28–0.89, and 0.55, 95%CI 0.38–0.89, respectively), whereas death rate was virtually identical across quartiles of HDL [13].
