Abstract

Key PointsQuestionWhat is the association between lipoprotein(a) and low-density lipoprotein–cholesterol concentrations and aortic stenosis events, and does proprotein convertase subtilisin/kexin type 9 inhibition reduce the risk of aortic stenosis events? FindingsIn this secondary analysis of 63 patients in a randomized clinical trial, elevated lipoprotein(a) concentrations were associated with higher rates of aortic stenosis events, including aortic valve replacement. The overall hazard ratio for aortic stenosis events with evolocumab was 0.66 (95% CI, 0.40-1.09), with no apparent association in the first year (hazard ratio, 1.09 [95% CI, 0.48-2.47]) but a hazard ratio of 0.48 (95% CI, 0.25-0.93) after the first year of treatment. MeaningLong-term therapy with evolocumab may reduce the risk of aortic stenosis events, although these findings require validation in a dedicated randomized clinical trial.
