Abstract

 Background and Aim: Coronary artery bypass grafting with CPB is an effective surgical treatment of CAD with low morbidity and mortality. Besides long-term outcomes are excellent. In recent years application of OPCAB (Without CPB) technique is increasing. The aim of this study was clinical evaluation and electocardiographic changes in patient with coronary artery bypass with/without CPB. Materials and Methods: In this quasi-experimental study, from 22 Jun 2002 to 6 mar 2003 primary isolated coronary artery bypass graft was performed in 115 patients (75 patients off - pump and 40 patients on - pump) in Department of cardiac surgery Ghaem Hospital. In two groups, hospital outcome and the level of CK-MB, CTnI, ECG changes (to evaluate myocardial injury) were compared together postoperatively. Data were analyzed by x2, logistic regression and t tests. Results: Two groups were similar in terms of age (off-pump 56.3±9.3 year Vs on-pump 55.6±10.6), sex, Risk factor, Preoperative EF, Extend of coronary disease, functional class, average of grafts (off- pump 4.09±0.9 Vs on-pump 4.02±0.7). Mean postoperative CK-MB level was (off-pump 39.3±36.7 U/lit Vs on-pump 56.68±33 U/lit) significantly less in off-pump group (P=0.03). Similar results were obtained also for CTnI (off-pump had 8% weakly positive and 6.7% positive Vs on-pump 17.5% weakly positive and 15% positive) (P=0.03). Postoperative and Discharge ECGs were similar in the two groups for new Q and ST changes (P=0.62). ICU and Hospital length of stay, intubation time, arrythmia, hemodynamic state, neurologic and perioperative mortality defects were not significant in two groups. Postoperative hemorrhage (P=0.009) and need for allogenic blood transfusion during the first postoperative 24 hours were significantly (0.044) less in off-pump group. Conclusion: Enzymatic changes (Myocardial injury) in off-Pump technique is less than on pump and these changes were more reliable than ECG changes. OPCAB is safe for CAD.
