Data are presented as percentages.
*p Value for interaction of patients with STEMI with AF for each outcome. This tests whether the association of AF and outcome is different for patients with STEMI and those with NSTE-ACS.
AF, atrial fibrillation; MI, myocardial infarction; NSTE-ACS, non-ST-segment elevation acute coronary syndrome; STEMI, ST-segment elevation myocardial infarction.
