Background and aims. We aimed to compare the prevalence of postsurgery chronic pain (PSCP) between patients who had undergo staged hybrid ablation (HA) for atrial fibrillation and those who had undergo conventional cardiac surgeries (CS).
Methods. 38 HA patients (age 64±9.5, 58% M, education 13.6y±2,7) and 42 CS patients (age 67±8.5, 81% M, education13.6y±3,3, coronary artery bypass graft (CABG) 38%, heart valve surgery 31%, mixed CABG/valve surgery 31%) completed self-report tools before surgery, 3 and 12 months thereafter. Questionnaires measured depression (BDI-II), anxiety (GAD-7), pain intensity/unpleasantness, location (VAS, Margoles), fear-related pain (FPQ-III).
Results. The two groups did not differed significantly regarding the prevalence of PSCP in 3 months after surgery, but differed significantly in 12 monts after surgery (Fisher's test, p=0.017). In the HA group 21% (n-7) patients experienced PSCP compared to 48% (n-20) patients in OCS group. We found strong significant positive correlation between intensity of pain and depression before (r=0.361, p=0.026; r=0.353, p=0.028) and 3 months after surgery in both groups ( r=0.375, p=0.038; r=0,414, p=0,007). Regression analysis in HA group indicated that higher depression and lower anxiety presurgically were predictive factors for PSCP in 3 months (p=0.091, p=0.019); higher intensity of pain and lower education were predictive factors for PSCP in 3 (p=0.026, p=0.020) and 12 months (p=0.005, p=0.031). We did not find anxiety and depression as significant predictors in OCS group. 
Conclusions. The rate of PSCP was less in patients undergoing HA comparing OCS in one year folow up. PSCP in HA group was significantly predicted by preoperative anxiety and depression.
