We aimed to evaluate the safety and efficacy of APT use in a \u2018real\u2010world\u2019 cohort of nonvalvular atrial fibrillation (NVAF) patients initiating NOAC.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p>We conducted a retrospective multicentre study including 2361 consecutive NVAF patients initiating NOAC between January 2013 and December 2016. Patients with an acute ischaemic event within the last 12\u00a0months (acute coronary syndrome, stroke or revascularization) were excluded. Patients were followed up, and all clinical events were recorded at 3\u00a0months. The primary outcome of the study was major bleeding, and the secondary outcomes were stroke, nonfatal myocardial infarction, intracranial bleeding and death.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred forty\u2010five (6.1%) patients received concomitant APT, and aspirin was the more common (79%). At 3\u00a0months, 25 (1.1%) patients had major bleeding, 8 (0.3%) had nonfatal myocardial infarction, 7 (0.3%) had ischaemic stroke, and 40 (1.7%) died.
