Few studies have examined the impact of preoperative atrial fibrillation (PreAF) on long-term survival after open heart surgery.
Patients undergoing CABG and CABG plus valve surgery at our institution between 2002 and 2011 were included in this study. Patients with and without PreAF were compared with respect to long-term survival. Hazard ratios (HR) and 95% CIs were computed using a Cox regression model.
PreAF patients had significantly decreased long-term survival than those without PreAF (Table 1). HRs remained increased after adjusting for age, sex, race, diabetes, HTN, CAD, CHF, and CVA (Overall: HR=1.6, p<0.0001; CABG: HR=1.6, p=0.0003; CABG + Valve: HR=1.6, p=0.015).
PreAF is an important predictor of long-term survival after open heart surgery.
