RESUMO
A análise da experiência com o emprego da angioplastia coronária primária no infarto agudo do miocárdio, sem uso prévio de substâncias líticas. Duzentos e um pacientes com infarto do miocárdio, cujas idades variaram de 35 a 86 (média de 57,2 anos), sendo 83,5% do sexo masculino. Viente casos tinham idade acima de 70 anos e em 48,2% o infarto era na parede anterior. A angioplastia foi praticada nas primeiras horas do infarto, com retardo de 12 horas, sendo 79% abaixo de 6 horas. Em 95% dilatou-se apenas a artéria relacionada ao infarto agudo. Setenta por cento dos casos encontravam-se no grupo I da classificaçäo de Killip, 21% no II, 8% nos III e IV (destes, mais de 50% em choque cardiogênico). O sucesso primário foi de 84,5%. A mortalidade hospitalar foi de 5,9%. Ocorreram 7% de reinfartos. Dos 84 casos submetidos a estudo angiográfico tardio, observou-se 19% de reestenoses, 8,3% de reoclusöes. A evoluçäo tardia mostrou 74,8% de assintomáticos, 2% de novos infartos; em 10,8% cirurgia de revascularizaçäo. A mortalidade pós-hospitalar foi de 8,8% em um período médio de evoluçäo de 28 meses (variando de 2 a 72 meses). A angioplastia coronária isolada mostrou-se efetiva como método de reperfusäo, exibindo altas taxas de sucesso, baixo índice de complicaçöes e, praticamente, sem contra-indicaçöes ao seu emprego
ABSTRACT
Purpose To evaluate the experience with the use of primary PTCA in the set of acute myocardial infarction (AMI) without the previous admnistration of thrombolytic agents. Patients and Methods Two hundred and one patients with AMI, aged 35 to 86 years (mean = 57.2). There were 83.5% men. Twenty patients were older than 70 years and 48.2% had an anterior AMI. PTCA was performed early in the AMI, with a delay no longer than 12 hours. In 95%, it was done solely to the infarct related artery. Seventy percent patients were in Killip class I, 21% in class II, and 8% in classes III and IV (more than 50% of this subset of patients were in cardiogenic shock). Results Primary success was achieved in 84.5%. In hospital mortality was 5.9%, and there were 7% reinfarctions. Among the 84 patients who underwent a late cinecoronariography study, there were 19% restenosis and 8.3% reoclusions. In the long term follow up 75% were asymptomatic. Repeat PTCA was required in 10.2% of the cases, late coronary surgery was performed on 10.8% of the patients, and post-hospital cardiac mortality was 8,8% during an average follow up of 28 months (range 2-72 months). Conclusion Primary PTCA is a effective way of reperfusion in the AMI, with a high primary success, low complications rate and without any major contraindications
