Abstract

Background: The aim of this study was to assess the frequency of all-cause rehospitalization and due to atrial fibrillation/flutter (AF/AFl), repeat ablation of AF/AFl, mortality within 30 days and 1-year follow-up in patients after AF/AFl ablation procedure.

Methods: Using data from the National Health Fund we identified a database comprising 2,022 patients who underwent AF/AFl ablation between January, 2012 and December, 2012 in Poland. The primary endpoint was readmission to hospital with discharge diagnosis AF/AFl. The secondary endpoints included: repeat AF/AFl ablation, cardiovascular hospitalization, all-cause hospitalization, all-cause mortality assessed in 30-day and 1-year time frame.

Results: The mean age was 58.6 ± 10.9 years (66.8% male). The mean time of the index ablation hospitalization was 3.8 ± 2.6 days. After discharge, 123 (6.1%) and 540 (26.7%) patients were hospitalized because of AF/AFl within 30 days and 1 year, respectively. During 1-year follow-up, 192 (9.5%) patients underwent subsequent AF/AFl ablations. The patients that underwent the second ablation were younger (56.6 ± 11.0 vs. 59.1 ± 10.8; p = 0.019) and the time of the index hospitalization was shorter (3.75 ± 2.16 vs. 4.45 ± 3.26; p = 0.03). Within 30 days 194 (9.6%) patients were hospitalized and 747 (36.9%) in 1-year follow-up. All-cause mortality was 0.1% and 1.4% in 30-day and 1-year follow-up, respectively. In a 1-year follow-up patients hospitalized from AF/AFl recurrence were more frequently hospital­ized due to cardiovascular diseases other than AF/AFl (9.6% vs. 6.7%; p = 0.026), especially due to hypertension (2.9% vs. 0.7%; p < 0.001).

Conclusions: Over 1 out of 4 patients who underwent AF/AFl ablation were hospitalized due to arrhythmia recurrence in 1 year.
