Abstract

AIMS: The relationship between atrial fibrillation (AF) and myocardial infarction (MI) remain unclear. We aimed to examine the sex-specific risk of MI, ST-segment elevation MI (STEMI) and non-ST-segment elevation MI (NSTEMI) in participants with AF, overall and by time since AF diagnosis. METHODS AND RESULTS: We followed 25 132 participants (53% women) from the Tromsø Study (1994-95) without AF and MI at baseline through 2021. Cox proportional- and Fine-Gray sub-distribution-hazard regression assessed AF as a risk factor for MI, STEMI and NSTEMI overall and by time since AF diagnosis (0 to
