[Myocardial revascularization after reperfusion in the acute phase of myocardial infarction].
OBJECTIVE
To evaluate the coronary artery bypass grafting (CABG) after successful coronary reperfusion (CR) by streptokinase and/or percutaneous transluminal coronary angioplasty in acute myocardial infarction (AMI).


METHODS
During 65-months period, 245 patients underwent CR during AMI. In 47 (19.2%) CABG were performed in the acute period due to multi-vessel disease (31%), residual lesion (20%) and post-reperfusion angina (17%). There were two distinct periods: in the first, between Jun/81 and Jun/83, 34 patients underwent CABG, 47 hours average after reperfusion; in the second, between Jul/83 and Nov/86, 13 patients underwent CABG, 7 days average after reperfusion.


RESULTS
There were 7 deaths (21%) in the first period and 1 (8%) in the second one.


CONCLUSIONS
After a multifactorial analysis the authors concluded that better results with inferior mortality (p less than 0.05) were obtained when CABG was performed later (mean 7 days) than in the immediate post-reperfusion period (mean 47 hours).
