Buckley BJR, Harrison SL, Fazio‐Eynullayeva E, et al. - Researchers undertook this retrospective cohort study to compare patients with atrial fibrillation (AF) and an electronic medical record of exercise‐based cardiac rehabilitation (CR) vs matched controls, with a focus on 18‐month all‐cause mortality, hospitalization, stroke, and heart failure. Data were collected from a global federated health research network. Using propensity‐scoring, AF patients receiving exercise‐based CR were matched to patients with AF without exercise‐based CR by age, gender, race, comorbidities, cardiovascular procedures, and cardiovascular medication. Findings revealed lower odds of all‐cause mortality, rehospitalization, and incident stroke, at 18‐month follow‐up, in relation to exercise‐based CR in patients with incident AF, thus, provision of exercise‐based CR for AF cases is supported.
