Key clinical point: Genetic liability to multiple sclerosis (MS) was associated with an increased risk for coronary artery disease (CAD), myocardial infarction (MI), heart failure (HF), all-cause stroke (AS), and any ischemic stroke (AIS), but not atrial fibrillation (AF) or other stroke subtypes.
Major finding: Genetic liability to MS was associated with an increased risk for CAD (odds ratio [OR] 1.02; P = .03), MI (OR 1.03; P = .01), HF (OR 1.02; P = .02), AS (OR 1.02; P = .02), and AIS (OR 1.02; P = .04), but not with AF or other stroke subtypes.
Study details: This was a two-sample Mendelian randomization analysis of genetic summary data for 47,429 MS (68,374 healthy controls [HC]), 60,801 CAD (123,504 HC), and 43,676 MI (128,199 HC), 60,620 AF (970,216 HC), and 47,309 HF (930,014 HC) cases from large-scale genome-wide association studies.
Disclosures: The study was supported by grants from Key Laboratory of Precision Medicine for Atherosclerotic Diseases of Zhejiang, China, the Major Project of Science and Technology Innovation 2025 in Ningbo, and others . The authors declared no conflicts of interest.
