The risk for stroke of \u201cearly\u201d versus \u201clate\u201d onset of atrial fibrillation (AF) has not been elucidated. Consecutively, AMI patients admitted to a tertiary medical center were analyzed. We excluded patients with preexisting AF, AMI onset \u226524 hours prior to admission, significant valvular disease, fever &gt;38.5\u00b0C, in-hospital death, or coronary artery bypass graft. Atrial fibrillation was verified by electrocardiography and medical records. Overall 7061 patients were included, 1.4% developed \u201cearly-paroxysmal AF (PAF)\u201d that resolved within 24 hours of admission and 2.5% had \u201clate-AF\u201d beyond the first 24 hours. Median follow-up was \u22486 years. Primary end points included ischemic stroke and all-cause mortality. Stroke rates were higher only in patients with late-AF versus no-AF but not in the early-PAF: 10.6% versus 4.2%, 5.3%, respectively ( P &lt; .001). Death rates were higher in patients with late-AF and early-PAF versus no-AF: 55.3%, 43.2%, and 29.2%, respectively ( P &lt; .001). Congestive heart failure, hypertension, age \u226575, diabetes mellitus, a stroke or transient ischemic attack, vascular disease, age 65-74, female (CHA\n                    <jats:sub>2<\/jats:sub>\n                    DS\n                    <jats:sub>2<\/jats:sub>\n                    -VASc) score underestimated stroke risk in the late-AF group. In conclusion, the study generates the hypothesis that patients with early-PAF may not have a high stroke risk questioning the indication for long-term anticoagulation.\n
