[Intracoronary thrombolysis and coronary artery bypass grafting--the favorable results of combined revascularization for myocardial infarction].
The results of coronary artery bypass grafting performed in 10 patients receiving intracoronary thrombolysis were reviewed. There were 9 males and 1 female. The mean age was 60.5 years old ranged from 41 to 77 years old. The obstructed vessels were the left anterior descending artery: 6, the right coronary artery system: 1, both the left anterior descending artery and the right coronary artery system: 1, and the left main trunk: 2. All patients survived after successful recanalization with constrict monitoring, systemic heparinization and oral anti-coagulants. All the patients received elective coronary revascularization for the occluded vessels and the other vessels, and the mean number of distal anastomoses was 2.8 ranged from 1 to 4. There were no operative deaths, no perioperative myocardial infarction, no use of balloon pumping or no serious complications. Symptomatic relief was obtained 10 of 10 patients. Left ventriculographic studies showed significant improvement in regional and global left ventricular ejection fraction after coronary artery bypass grafting compared with after thrombolysis. In conclusion, successful thrombolysis for acute myocardial infarction reduces early mortality. Additional coronary artery bypass grafting is beneficial for not only definite correction of the underlying arteriosclerotic lesion, but also improvement of left ventricular function.
