| Popis: | Two hundred twenty-seven consecutive patients had chest pain and electrocardiographic, coronary angiographic, ventriculographic, and retrospective enzyme changes consistent with acute evolving myocardial infarction (AEMI). These patients underwent coronary artery bypass grafting an average of less than 6 hours after the start of chest pain. The mean age was 55.8 years (range 28 to 79 years). Sex, coronary artery involvement, and preoperative and postoperative enzymes and electrocardiograms are presented. Follow-up angiocardiograms done an average of 12.7 months postoperatively revealed 99 patent primary grafts in 102 patients (94.3%). Ejection fractions were normal, unchanged, or improved in 86.3% of the patients. Two ventricular aneurysms measuring less than 2.5 cm in diameter were noted. Surgical in-hospital mortality was 1.76% and first-year mortality was 1.44%. Conventional therapy in 200 AEMI patients treated at the same hospitals resulted in an in-hospital mortality of 11.5%. Follow-up of 213 patients having coronary artery bypass grafting revealed that 14% had mild angina. AEMI interrupted by coronary artery bypass grafting early in the syndrome yields results which are superior to conventional management. |
