Effects of N-acetylcysteine on myocardial ischemia-reperfusion injury in bypass surgery.
Myocardial ischemia-reperfusion injury may complicate coronary artery bypass grafting (CABG) operations. N-Acetylcysteine (NAC) had antioxidant and microcirculatory effects, and inhibits neutrophil aggregation. The aim of this study was to determine the effects of NAC in limiting myocardial ischemia-reperfusion injury in CABG operations. ⋯ Creatine kinase-MB levels at 6 and 12 hours were significantly lower in the NAC group (P = 0.02). N-Acetylcysteine has potential effects to limit ischemia reperfusion injury during CABG operations. We believe that its effects on clinical outcome may be more apparent in patients prone to ischemia-reperfusion injury.
