Health-related quality of life changes in patients undergoing repeated catheter ablation for atrial fibrillation

摘要: Pulmonary vein isolation (PVI) for paroxysmal or non-paroxysmal atrial fibrillation (AF) should increase health-related quality of life (QOL). Retrospective cohort study consecutive patients scheduled PVI. University Medical Center. QOL was assessed using the physical (PCS) and mental (MCS) component summary scores from SF-12v2 in undergoing PVI (mean 50, range 0–100, with higher indicating greater QOL). obtained at initial presentation (3-months) before after end follow-up 1.7 ± 1.4 years) which included: (1) Clinical status, ECG, 24-h ECG every 3 months, (2) trans-telephonic ECGs 4 weeks (3) continuous via implanted devices. A recurrence any arrhythmia >30 s. Out 229 (73 % males; 58 ± 11 years), 72 % returned regarding 187 procedures: 56 % 1st PVI, 48 % 2nd 71 % 3rd 44 % 4th The mean difference between 10 PCS 9 MCS. History AF did not influence (p = 0.724). Patients an estimated improvement ≥10 MCS ≥9 had best outcome repeated Success rates were 72 82 % 1 year compared to 20 22 % achieving this improvement, respectively (p < 0.0001). Improvement correlates success ablation single Assessment pre- post-PVI can complement techniques monitoring.
