The coronary artery bypass surgery is frequently used to treat the residual lesion after myocardial infarction reperfusion. Patients may undergo surgery during the acute or late phase. This study analyses the results of 45/159 (28%) patients who underwent a coronary bypass surgery after successful myocardial reperfusion with streptokinase or percutaneous transluminal coronary angioplasty (PTCA). Patients were divided into two groups accordingly to the reperfusion technique: I) 27 (60%) reperfused with the use of streptokinase, intracoronary in 22 (81%) and intravenous in 5 (18%); II) 18 (40%) reperfused with the aid of PTCA, alone in 10 (55%) and following previous streptokinase in 8 (45%). Patientes were analysed at the moment of surgery, clinical evolution, late cinecoronariography and death, and were followed from 2 to 55 months. Authors analise the results and the capacity of bypass surgery complement successfull myocardial reperfusion during acute myocardial infarction.
