Comparative Study On Off-pump Versus On-pump Coronary Artery Bypass Grafting Through Detection Of The Cardial Troponin

[Objective] To evaluate the advantages of off-pump coronary artery bypass(OPCAB) through detection of the cardial troponin. [Methods] 36 cases in OPCAB(OPCAB group) were compared to 36cases in coronary artery bypass grafting (CABG; control group). The plasma level of cardial troponin was observed in both groups. And the early postoperative clinical results were assessed.[Results] No significance difference was observed in basic clinical data in both groups. The mean level of plasma cardial troponin I was normal in OPCAB group in the 4, 8 ,16 24h ,2 ,4, 8d after operation. The frequency of the positive changes of ECG is less in PCAB group than that in control group. [Conclusions] If seems that OPCAB provide better myocardial protection and better early results than CABG.
