Аннотация
BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia following open-heart surgery. Agents with antioxidant properties may reduce postoperative complications like postoperative AF (POAF) in patients undergoing open-heart surgery. This study was conducted to assess the effect of N-acetylcysteine (NAC) in prevention of AF following coronary artery bypass graft (CABG) surgery.
METHODS: Three hundred patients who underwent CABG surgery were entered in the study. Patients with contraindications for beta-blockers and patients were simultaneously replacing or repairing the valve with open-heart surgery were excluded. The patients were randomly divided into two groups (n = 150) and they were received NAC plus carvedilol or carvedilol. The patients were monitored for 5 days after surgery and the incidence of AF during hospitalization was recorded.
RESULTS: AF was detected in 14 patients in the NAC with Carvedilol group (9.33%) and 23 patients in Carvedilol group (15.33%). There was no significant difference in the incidence of POAF between the two groups (p value = 0.112). The result of multivariable regression model represented that although the incidence of POAF was lower in NAC plus carvedilol group, it wasn't statistically significant (p value = 0.10).
CONCLUSIONS: NAC was not associated with a decreased incidence of AF following CABG surgery.
