Table 2 Preoperative characteristics of patients with longstanding persistent AF

From: Impact of epicardial ablation of concomitant atrial fibrillation on atrial natriuretic peptide levels and atrial function in 6 months follow-up: does preoperative ANP level predict outcome of ablation?

  AF at 6 months SR at 6 months p value
Age (yrs) 78.0 (66.25-79.25) 74.5 (62.5-80.0) 0.87
Gender (male/female) 8/3 11/3 1.0
Duration of AF (yrs) 8.0 (3–10) 5.0 (3–9,5) 0.39
LAD (preop.) [mm] 53.1 ± 6.2 47.1 ± 6.2 0.01
LA area (preop.) [cm 2 ] 33.95 (27.92-35.89) 27.84 (26.3-30.2) 0.03
ANP (preop.) [nmol/l] 6.86 (5.68-8.06) 9,995 (7.53-14.02) 0.009
