[Myocardial revascularization. The evolution of 100 cases].
The postoperative course of 100 pts. that underwent aorto-coronary bypass surgery was studied at the Instituto Nacional de Cardiología "Ignacio Chávez": 84 were men and 16 women between 37 and 74 years. 56 had previous history of myocardial infarction, while in 16 of them occurred within 30 days of the surgical procedure. 88 had symptomatic angina and 8 were in cardiac failure. The coronariography showed trivascular lesions in 73% and 8 pts. had stenosis of the left main coronary artery. Two pts. had 5 coronary grafts, 4 had 17, 3 had 37, two 35 and one 9 pts. All anterior descending coronary arteries were grafted. 61 of them and the 8 main left damaged were grafted with internal mammary artery Afert surgery; 15 pts had AMI, 4 profuse bleeding, one cardiac failure and shock. CPK enzyme levels of 500 were found in the majority of the pts with AMI with 81.2 positive predictive value and negative of 97.6. Three pts died, two at the OR with cardiac failure one of them had ventricular rupture, and the last at the ICU also with cardiac failure. We emphasize that CPK values of 500 UI or more in the postoperative course may be diagnostic of AMI.
