[Improvement of quality of life after ablation of longstanding persistent versus paroxysmal atrial fibrillation: results of 2-year follow-up]. / Zlepsení kvality zivota po ablaci dlouhodobe perzistentní versus paroxysmální fibrilace síní: výsledky dvouletého sledování.

AIMS: The purpose of the study was to assess quality of life and socio-economic parameters in patients after ablation of paroxysmal versus longstanding persistent atrial fibrillation (AF). METHODS: The study included 89 patients with paroxysmal AF and 56 patients with longstanding persistent AF who underwent ablation within 1 year, and were afterwards prospectively followed up for 2 years. Quality of life was evaluated by the EQ-5D questionnaire before and every 6 months after ablation. RESULTS: Objective, respectively subjective quality of life at baseline was lower in patients with longstanding persistent AF (67 +/- 16 vs 71 +/- 10; p = 0.01, resp. 64 +/- 12 vs 67 +/- 16; p = 0.07); however, after 2 years, it exceeded that of the patients with paroxysmal AF (80 +/- 17 vs 75 +/- 18; p = 0.03; resp. 73 +/- 13 vs 70 +/- 17; p = 0.18). The baseline-2 year difference in improvement was higher in patients with longstanding persistent AF in both objective (p = 0.001) and subjective component (p = 0.05). Both groups displayed significant decrease in the days of hospitalization, and the days of working incapacity. CONCLUSION: Patients with longstanding persistent AF exhibit worse baseline quality of life than the patients with paroxysmal AF, and higher quality of life improvement after ablation.
