Randomized Trial of Cholesterol Lowering With Evolocumab for Cardiac Allograft Vasculopathy in Heart Transplant Recipients

Cardiac allograft vasculopathy is characterized by increased coronary intimal thickness and is a leading cause of death in heart transplant (HTx) recipients despite the routine use of statins. The experience with inhibitors of proprotein convertase subtilisin-kexin type 9 in HTx recipients is limited. Our hypothesis was that lowering cholesterol with the proprotein convertase subtilisin-kexin type 9inhibitor evolocumab would reduce coronary intimal thickness in these patients without compromising safety.
