Background: Coronary artery calcium (CAC) scoring predicts cardiovascular risk, but social determinants of health may play a role in its prognostic ability. We examined whether the Social Vulnerability Index (SVI) modifies the association between CAC and major adverse cardiovascular events (MACE) in a community-based screening cohort.
Methods: We studied 49 224 participants without known cardiovascular disease referred for CAC scanning from 2014 to 2022 based on cardiovascular risk factors.
