Background: Studies have demonstrated that catheter ablation of atrial fibrillation is associated with better rhythm control than drug therapy. The present study aimed to assess the clinical outcomes and health-related quality of life of ablation therapy in a real world setting.Methods: A prospective, non-randomized, single center study in a real-world clinical setting in China was conducted. Patients were followed up at 3, 6, and 9 months after baseline encounter. Propensity score matched patients receiving ablation or anti-arrhythmic drug therapy were compared. Incidence rate of atrial fibrillation recurrence and quality of life outcomes were measured and analyzed using log-rank test, multivariate logistic regression and mixed-effects linear regression respectively.Results: In this study, 151 atrial fibrillation patients treated by ablation therapy and 318 patients treated by anti-arrhythmic drugs were enrolled. During follow up, 82.0% in the ablation arm and 22.4% in the drug arm had no documented atrial fibrillation recurrence [HR for atrial fibrillation recurrence 0.07 (95%CI: 0.02-0.21, p < 0.0001)] among paroxysmal atrial fibrillation patients. The corresponding no recurrent rate were 66.7% and 18.5% [0.21 (0.05-0.95, p = 0.04)] respectively among persistent atrial fibrillation patients. Improvement in Short Form-36 physical component scores, Short Form-36 mental component scores and total Atrial Fibrillation Effect on Quality-of-life scores were 16.33 (14.05-18.61, p < 0.001), 8.10 (6.11-10.09, p < 0.001) and 18.28 (16.11-20.45, p < 0.001) respectively among paroxysmal AF patients and 6.32 (3.15-9.49, p < 0.001), 3.99 (1.82-6.16, p < 0.001) and 13.97 (10.89-17.05, p < 0.001) respectively among persistent AF patients. Improvements in total Atrial Fibrillation Effect on Quality-of-life score were also significant in ablation arm while no significant improvement of total Atrial Fibrillation Effect on Quality-of-life score in the drug arm.Conclusion: Compared with drug therapy, catheter ablation is associated with significant lower AF recurrence and improved overall quality of life.Trial Registration: The present study has been registered on clinicaltrials.gov.

Background: Robust data on the contemporary management of atrial fibrillation (AF) patients in China are limited. Importantly current practice in AF management has changing dramatically in recent years. Data from a large registry study will enable us to evaluate the uptake and outcomes with different therapies in a large Chinese AF population.Methods/design: The Chinese Atrial Fibrillation Registry study (CAFR) aims to enroll 20,000 consecutive atrial fibrillation (AF) patients from 32 tertiary and non-tertiary hospitals in Beijing, China, and follow up these patients every 6 months until 2020. Key data collected includes basic sociodemographic information, symptoms and signs, medical history, results of physical examination and laboratory test, details of treatments and personal insurance status. For patients who consent, 5 ml of blood sample will be stored at -80 °C for future analyses of biomarkers. At each 6 month follow up visit, data relating to clinical outcomes will be collected. Data from a randomly selected 10 % of patients will be internally validated with their raw source data. Ischemic stroke events will be adjudicated by an independent endpoint committee.Discussion: CAFR will be one of the largest registries of Asian AF patients (and the largest in Chinese AF patients), as well as providing the longest follow up. This study would provide a valuable opportunity for 'real world' clinical epidemiology with insights into the uptake (and outcomes) of contemporary AF management.Trial Registration: Chinese Clinical Trial Registry ChiCTR-OCH-13003729 .
