ABSTRACT
PURPOSE--Prospective evaluation of the effects of the intravenous administration of rt-PA (Alteplase) up to 6 hours after the pain onset on the patency of the AMI related artery, mortality, adverse reactions and complications. METHODS--Open, multicenter, non-comparative study involving 139 patients with diagnosis of AMI, with less than 6h of duration. The rt-PA was intravenously administered, in a dose of 100mg, as follows 10mg in the 1st 2min, 50mg in 58min and 40mg in 120min. In addition, the patients received intravenous heparin (5000 IU at first and then, 1000 IU/hour, for 24h), aspirin (500mg in the 1st day and then, 100mg/day) and dipyridamole (75mg, three times a day), during the hospitalization period. The angiographic study was performed in 129 (93) patients, within the 1st week of AMI. RESULTS--The age of the patients ranged from 29 to 85 (mean 56.6 +/- 10.3) years. The related artery for the AMI was patent (TIMI II and III flow) in 92/129 (71) patients, with a mean ejection fraction of 50 +/- 14, a value higher than that exhibited by patients with TIMI 0 and I flow (average ejection fraction = 44 +/- 14). Reinfarction was diagnosed in 9 (6.4) patients during the hospitalization period. During this period, there were 9 (6.4) deaths. Minor hemorrhages were observed in 19 (12) patients and major hemorrhages in 3 (2) cases. No patient experienced stroke. CONCLUSION--The administration of the rt-PA therapy in the AMI was associated to a high reperfusion index of the related artery for the infarction, with improved left ventricular function and low incidence of reinfarction and in-hospital mortality, as well as, complications.
RESUMO
Objetivo - Avaliar prospectivamente os efeitos dort-PA (alteplase), administrado por via intravenosa (IV) até 6h após início da dor, na perviabilidade da artéria responsável pelo infarto agúdo do miocárdio (IAM), na morbimortalidade, nas reações adversas e nas complicações. Métodos - Estudo multicêntrico, aberto, não comparativo, envolvendo 139 pacientes com diagnóstico de IAM, com menos de 6h de duração. O rt-PA foi administrado por via IV, na dose de 100mg, assim distribuída 10mg nos 2min iniciais, 50mg em 58min e 40mg em 120min. Os pacientes receberam, ademais, heparina via IV (5.000UI iniciais e 1.000UI/h, durante 24h), aspirina (500mg no 1º dia e, a seguir, 100mg/dia) e dipiridamol (75mg, 3 vezes ao dia), durante período de internação. Estudo cinecoronariográfico foi realizado em 129 (93%) pacientes, dentro da Iª semana do IAM. Resultados - As idades dos pacientes variaram de 29 a 85 (média 56,6 10,3) anos, sendo 80% do sexo masculino. A artéria responsável pelo IAM estava pérvia (fluxo TIMI II e III) em 92/129 (71%) pacientes, os quais apresentaram fração de ejeção média (FEm) =50 14%, valor esse maior do que o dos pacientes com fluxo TIMI 0 e I (FEm = 4414%). Reinfarto foi diagnosticado em 9 (6,4%) pacientes durante o período de internação hospitalar. Nesse período, ocorreram 9 (6,4%) óbitos. Hemorragias menores foram observadas em 19 (12%) pacientes e hemorragias maiores em 3 (2%) casos. Nenhum paciente apresentou acidente vascular cerebral. Conclusão - A terapêutica com rt-PA no IAM associou-se a elevado índice de reperfusão da artéria responsável pelo infarto, com melhora da função ventricular esquerda e baixa incidência de reinfarto e de mortalidade hospitalar, bem como de complicações
