ABSTRACT Among ischemic strokes, cardioembolic (CE) stroke has the worst outcome. We measured the incidence of atrial fibrillation (AF) and non-AF related CE strokes, previous anticoagulant use, and the 90-day functional outcome. Using multiple overlapping sources, we included all CE strokes that occurred in 2015 in Joinville, Brazil. Of the 374 ischemic strokes, 23% (84) were CE. The CE age-adjusted incidence, per 1,000 person-years, was 0.14 (0.11–0.17). Of the 26 patients with known prior AF, 73% (19) were not anticoagulated, 77% (20) had a CHA2DS2VASc score ≥ 3 and 81% (21) had a HAS-BLED score < 3. After three months, approximately one third of those 26 patients died or became disabled. The incidence of CE stroke in our sample was lower than in other population-based studies. The opportunity for anticoagulation was missed in one third of cases.
