Abstract
Background: Atrial fibrillation (AF) is associated with adverse remodeling of the left atrium (LA). The impact of the extent of atrial myopathy and post-ablation remodeling on quality-of-life (QoL) outcomes has not been studied.
Objective: The aim of our study was to investigate the association between atrial myopathy and post-ablation remodeling on quality-of-life outcomes in patients with persistent AF.
Methods: We conducted an analysis of DECAAF II participants who underwent late-gadolinium enhancement MRI (LGE-MRI) before and after AF ablation. We assessed atrial myopathy and post-ablation atrial remodeling, scar formation, and fibrosis coverage with ablation. QoL metrics were assessed using the Short Form Survey (SF-36) and Atrial Fibrillation Severity Scale (AFSS). Uni- and multivariable regression models were developed for this analysis.
Results: Six hundred thirteen patients with persistent AF were included in our analyses. At baseline, AFSS burden and total AFSS score were 18.94 ± 7.35 and 12.24 ± 8.17, respectively. Following ablation, all QoL and AFSS metrics improved in both the pulmonary vein isolation (PVI) and MRI-guided fibrosis ablation groups. On average, one unit of post-ablation reduction in left atrial volume index (LAVI) was associated with an improvement of 0.085 in total AFSS score (p = 0.001), 0.01 in shortness of breath with activity (p < 0.001), 0.15 in AF burden (p < 0.001), - 0.016 in global well-being (p = 0.018), 0.519 in health change (p < 0.001), 0.19 in vitality (vitality (p = 0.01), and 0.27 in physical functioning (p = 0.001). Baseline fibrosis and residual fibrosis post-ablation were associated with improved vitality and general health.
Conclusion: Atrial myopathy and post-ablation atrial remodeling significantly impact QoL in patients with persistent AF undergoing ablation.
期刊介绍：
The Journal of Interventional Cardiac Electrophysiology is an international publication devoted to fostering research in and development of interventional techniques and therapies for the management of cardiac arrhythmias. It is designed primarily to present original research studies and scholarly scientific reviews of basic and applied science and clinical research in this field. The Journal will adopt a multidisciplinary approach to link physical, experimental, and clinical sciences as applied to the development of and practice in interventional electrophysiology. The Journal will examine techniques ranging from molecular, chemical and pharmacologic therapies to device and ablation technology. Accordingly, original research in clinical, epidemiologic and basic science arenas will be considered for publication. Applied engineering or physical science studies pertaining to interventional electrophysiology will be encouraged. The Journal is committed to providing comprehensive and detailed treatment of major interventional therapies and innovative techniques in a structured and clinically relevant manner. It is directed at clinical practitioners and investigators in the rapidly growing field of interventional electrophysiology. The editorial staff and board reflect this bias and include noted international experts in this area with a wealth of expertise in basic and clinical investigation. Peer review of all submissions, conflict of interest guidelines and periodic editorial board review of all Journal policies have been established.
