Objective: CHADS2 and CHA2DS2-VASc scores are two widely used systems for evaluating the risk of stroke in patients with atrial fibrillation (AF). The Quality of life (QoL) after a single radiofrequency ablation (RFA) in AF patients with low CHADS2 score has been established. This study was designed to further explore the association between the QoL and AF patients with low CHA2DS2-VASc score after RFA., Methods: We selected 367 AF patients with low CHA2DS2-VASc score (CHA2DS2-VASc<2) from the Chinese Atrial Fibrillation Registry (CAFR) between 2011 and 2013. They all completed both baseline and 6-month Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaires. Propensity score matching was used to construct a final cohort of 105 patients. They were divided into two groups: RFA group (n=44) and non-RFA group (n=61)., Results: Baseline clinic characteristics, and each domain and global score of AFEQT were comparable between the two groups. Except for domain of treatment satisfaction in non-RFA group (mean score change from baseline to 6-month: 3.55, P= 0.13) , the other domains in this group (mean score change from baseline to 6-month: symptom, 14.66; daily activities, 12.56; treatment concern, 17.69; global score, 14.71, all P<0.05) and all the domains in RFA group improved greatly within-group comparison (mean score change from baseline to 6-month: symptom, 20.42; daily activities, 17.1; treatment concern, 20.36; global score, 18.75; treatment satisfaction, 9.66, all P<0.05). No significant differences were observed in all domains of baseline to 6-month changes between two groups (all P>0.05)., Conclusions: No significant changes could be viewed in QoL between RFA and non-RFA AF patients with low CHA2DS2-VASc score, whose baseline AFEQT were balanced, and QoL from baseline to 6-month improves significantly.

Objective: To analyze the long-term compliance of oral anticoagulant therapy and the demands of disease management in patient with atrial fibrillation (AF)., Methods: Inpatients with AF taking warfarin were collected from Department of Internal Medicine from January 1 to December 31, 2008. Inpatients from departments of surgery, ophthalmology, otorhinolaryngology, dermatology and pediatrics and those on a previous warfarin therapy were excluded. The data of patient profiles, medical history and anticoagulant treatment were collected from electronic medical record. And the status of anticoagulant treatment one year later and demands of disease management were inquired by telephone., Results: A total of 268 AF patients received a telephone survey. Among them, 145 patients (54.1%) continued taking warfarin. Gender, age, type of AF, duration of AF and history of ischemic stroke was not significantly associated with the compliance of anticoagulant treatment. The odds ratio was 1.74 (95%CI: 0.67-4.47), 0.87 (95%CI: 0.30-2.53), 1.59 (95%CI: 0.35-1.09), 1.09 (95%CI: 0.61-1.93) and 0.44 (95%CI: 0.12-1.60) respectively. Among patients on warfarin, INR was monitored monthly in 88 patients (60.7%) and 70 patients (48.3%) had an INR value of 2.0-3.0. Among 123 withdrawal patients, 88 patients (71.5%) terminated treatment within 6 month. The common reasons included patient ignorance about long-term anticoagulant treatment (35.0%) and switching to aspirin because of a poor effect (24.4%). About 80% of patients wished to obtain instructions about INR monitoring and adjustment of drug dosage. Among them, 196/268 patients (73.1%) wished for a regular follow-up. And 176/196 patients (89.8%) opted for a telephone follow-up and 150/176 patients (85.2%) wanted to receive monthly instructions., Conclusion: The compliance of anticoagulation treatment and the target-meeting proportion of INR value are relative low. And the common reasons of withdrawal are patient ignorance about long-term anticoagulant treatment and switching to aspirin because of a poor effect. Disease management will meet most of AF patients' demands.
