RESUMO
Acompanhamos para eventos cardíacos tardios (EC) 487 pts submetidos à ecocardiografia de contraste miocárdico ECM por 36+17 meses. Defeito reversível de perfusão foi positivo (POS) e normal ou defeito fixo isolado foi negativo (NEG). Os pts foram considerados de baixo(87), intermediário(94) e alto risco(141), ou com doença arterial coronária (DAC) confirmada(165). Foram documentados 85 EC: morte cardíaca (15), infarto do miocárdio (7) e revascularização miocárdica (63). POS foi preditor independente para EC. A sobrevida acumulada livre de eventos foi 96 por cento e 77 por cento para pts com ECM NEG e POS respectivamente (p<0,001). ECM é útil preditor para EC em pts com suspeita ou DAC confirmada / Long-term predictive value for late cardiac events (CE) was determined in 487 patients who underwent myocardial contrast echocardiography (MCE) and were followed up for 36+17 months. Reversible perfusion defects were positive (POS) and normal or isolated fixed defects were negative (NEG). Patients were at low (87), intermediate (94), high-risk (141), or with confirmed coronary disease (165). CE were: cardiac death (15), non-fatal myocardial infarction (7), and revascularization (63) patients. POS test was an independent predictor of CE. The cumulative event free survival was 96 per cent (NEG-MCE) and 77 per cent (POS-MCE), p<0.001. MCE was a useful predictor of CE...
