Associação entre acidentes vasculares encefálicos e doença de Chagas

Foi pesquisada a freqüência de acidentes vasculares encefálicos (A VE), isquêmicos e hemorrágicos, em chagásicos crônicos e em não chagásicos, maiores de 15 anos de idade, necropsiados em Uberaba, de 1979 a 1988, optando-se por estudo emparelhado por sexo e idade em 208 pares. Em 41 (19,7%) dos chagásicos e em 55 (26,4%) dos não chagásicos foram diagnosticados AVE, diferença não significante ao nível de 5%. Dos chagásicos 12 (75%) tiveram infarto e 4 (25%) hemorragia encefálica; dos não chagásicos 5 (31,3%) tiveram infarto e 11 (68,7%) hemorragia. As .diferenças são significantes ao nível de 5%. Os resultados demonstram menor freqüência de AVE hemorrágico em chagásicos que em não chagásicos e comprovam alta freqüência de AVE isqüêmico na doença de Chagas humana.<br>The frequency of strokes was studied in chronic chagasic and years ofage, non-chagasicpatients, older than 15 coming to necropsy in Uberaba, from 1979 than 1988. The study consisted of paired sex and age matched controls. Two hundred and eight pairs were analysed. Either ischemic or hemorrhagic strokes were found in 41 (19,7%) of the chagasics and in 55 (26.4%) of the non-chagasic, a difference not significant at the level of 5%. Twelve (75%) of the former had infarcts and 4(25%) had brain hemorrhage; five (31,3%) of the non-chagasics had ischemic strokes and 11 (68,7%) had hemorrhagic strokes. The differences were significant to the level of 5%. The results indicate a high frequency of ischemic strokes in human Chagas'disease and demonstrate a lesser frequency of hemorrhagic stroke in chagasics when compared with non-chagasics

Outcomes in Newly Diagnosed Atrial Fibrillation and History of Acute Coronary Syndromes: Insights from GARFIELD-AF

BACKGROUND: Many patients with atrial fibrillation have concomitant coronary artery disease with or without acute coronary syndromes and are in need of additional antithrombotic therapy. There are few data on the long-term clinical outcome of atrial fibrillation patients with a history of acute coronary syndrome. This is a 2-year study of atrial fibrillation patients with or without a history of acute coronary syndromes
