Abstrakt:	Background: 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. Objectives: This double blind, randomized trial was conducted to test whether evolocumab reduces the burden of cardiac allograft vasculopathy. Methods: Patients who had received a cardiac allograft at 1 of the Nordic transplant centers within the prior 4 to 8 weeks were randomized to monthly subcutaneous injections of evolocumab 420 mg or matching placebo. The primary endpoint was the baseline-adjusted maximal intimal thickness as measured by intracoronary ultrasound after 12 months' treatment. Results: The trial enrolled 128 patients between June 2019 and May 2022. Matched pairs of coronary ultrasound images were available for 56 patients assigned to evolocumab and 54 patients assigned to placebo. At 12 months, the adjusted mean difference in the maximal intimal thickness between the 2 arms was 0.017 mm (95% CI: -0.006 to 0.040; P = 0.14). The mean reduction in low-density lipoprotein cholesterol with evolocumab compared with placebo was 1.11 mmol/L (95% CI: 0.86-1.37 mmol/L). The use of evolocumab was not associated with an increase in adverse events. Conclusions: Twelve months of treatment with evolocumab substantially reduced low-density lipoprotein cholesterol but did not reduce maximal coronary intimal thickness in HTx recipients.
