ABSTRACT
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.
RESUMO
RESUMO Entre todos os subtipos de AVC isquêmico, os eventos cardioembólicos (CE) apresentam os piores prognósticos. Determinamos a incidência de AVC isquêmico CE, associada ou não à fibrilação atrial (FA), o uso prévio de anticoagulantes e os desfechos funcionais em Joinville, Brasil. Utilizando múltiplas e sobrepostas fontes de informação, registramos todos os primeiros eventos CE ocorridos em 2015. Entre 374 eventos isquêmicos, 23% (84) foram CE. A incidência ajustada, para qualquer fonte cardioembólica, foi 0.14 (0.11–0.17) por 1000 pessoas-ano. Entre 26 pacientes com FA previamente conhecida, 73% (19) não estavam anticoagulados, 77% (20) tinham ≥ 3 pontos na escala CHA2DS2VASc e 81 % (21) < 3 pontos na escala HAS-BLED. Após 3 meses, um terço destes 26 pacientes morreram ou ficaram dependentes. A incidência de AVC I CE em Joinville é menor do que em outros estudos de base populacional. Um terço dos casos de AVC I CE com FA previamente conhecida perderam a oportunidade de anticoagulação.
