[Improvement of quality of life after ablation of longstanding persistent versus paroxysmal atrial fibrillation: results of 2-year follow-up]

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.
