Background: We aimed to show reliability of surgical therapy that is being more favorite on early period of post myocardial infarctus (MI) and unstable angina pectoris (USAP) cases. Methods: Between January’ 97 and December `98, 18 patients who had post-MI angina occurred in less than 20 days (group 1) and 31 patients who had USAP but had not myocardial infarct in the last 2 months (group 2) were operated at our center and their preoperative, intraoperative and postoperative parameters were evaluated. Preoperative variables were; age, gender, smoking, hypertension, diabetes mellitus, previous myocardial infarct, less than % 30 ejection fraction, time of interval between hospital admittance and operation, properative nitroglycerine usage and existence of left main coronary artery disease. Also, both groups were compared for perioperative variables of; number of distal anastomoses, ITA usage, myocardial preservation, cross-clamp and bypass times. In both groups, postoperative variables of mortality, complications (low cardiac output, sternal dehiscence, and pulmonary dysfunction) and length of stay were analyzed. Results: No statistical difference was present in perioperative variables in both groups. Mortality was %22.2 (4/18) in the first group and %3.3 (1/30) in the second group (p< 0.05). Conclusions: Although mortality and morbidity are higher than in standard CABG operations we believe that these numbers are acceptable.
