ABSTRACT
It was suggested that intravenous thrombolysis (IT) leads to larger extent recanalization in cardioembolic stroke. In this work we assess if this has beneficial clinical traduction. METHOD: We evaluated 177 patients undergoing IT, which were categorized into cardioembolic (CE) and non-cardioembolic (NCE). National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale were compared. RESULTS: The mean age was 67.4±12.01 and 53.8 percent were male. The mean NIHSS was: 14 (admission), 9 (24 h) and 6 (discharge), similar in subgroups. The difference between NIHSS at admission and 24 hours was 4.17±4.92 (CE: 4.08±4.71; NCE: 4.27±5.17, p=0.900) and at admission and discharge there was an average difference of 6.74±5.58 (CE: 6.97±5.68; NCE: 6.49±5.49, p=0.622). The mRS at discharge and 3 months was not significantly different by subtype, although individuals whose event was NCE are more independent at 3 months. CONCLUSION: Ours findings argue against a specific paper of IT in CE. It can result from heterogeneity of NCE group.
Alguns estudos sugerem que a trombólise endovenosa (TE) conduz a melhor recanalização nos acidentes vasculares cerebrais isquêmicos (AVCI) cardioembólicos. Neste trabalho questionamos se isto terá tradução em benefício clínico. MÉTODO: Avaliamos 177 doentes submetidos a TE, os quais foram categorizados como cardioembólicos (CE) e não cardioembólicos (NCE). Compararam-se a National Institutes of Health Stroke Scale (NIHSS) e escala de Rankin modificada. RESULTADOS: A idade média foi 67,4±12,01 e 53,8 por cento eram homens. NIHSS média foi: 14 (admissão), 9 (24 h), 6 (alta), semelhante nos subgrupos. A diferença entre NIHSS à admissão e 24 h foi de 4,17±4,92 (CE: 4,08±4,71; NCE: 4,27±5,17, p=0,900) e entre a admissão e a alta de 6,74±5,58 (CE: 6,97±5,68; NCE: 6,49±5,49, p=0,622). A classificação na mRS não foi significativamente diferente nos subgrupos (alta e 3 meses), mas os doentes com eventos NCE estavam mais independentes aos 3 meses. CONCLUSÃO: Os nossos resultados não documentam um papel específico da TE nos CE, o que pode resultar da heterogeneidade do grupo NCE.

Se presenta el caso de un hombre de setenta y un años de edad quien presenta en forma súbita síntomas y signos isquémicos cerebrales. Tiene antecedente de fibrilación auricular crónica, prótesis valvular en posición aórtica y mitral, insuficiencia cardiaca y complicaciones hemorrágicas relacionadas con la anticoagulación. Como parte del estudio se realizó ecocardiograma transesofágico que demostró trombo mural gigante en la aurícula izquierda, el cual desapareció luego de nueve meses de tratamiento anticoagulante.
The case of a 71 years old male that suddenly presents ischemic brain signs and symptoms is presented. He had a previous history of chronic atrial fibrillation, mitral and aortic valve protheses, heart failure and bleeding related to anticoagulation. A transesophageal echocardiogram was performed as part of the assessment, showing a gigantic left atrial mural thrombus that disappeared after 9 months of anticoagulation therapy.
