Objective: To investigate the clinical features and current therapy of atrial fibrillation (AF) of inpatients in Urumqi, China., Methods: The clinical data of inpatients diagnosed with AF from January, 2008 to December, 2012, in 12 hospitals in Urumqi were retrospectively analyzed., Results: Totally 1 310 AF inpatients were enrolled in this study with the age of (64.8 ± 3.3) years old and a men to women ratio of 1.39. Most patients were in age groups of 61-70 years (26.5%) and 71-80 years (27.6%). More patients with paroxysmal AF were at cardiac function class I-II (75.2%), while more patients with persistent AF were at cardiac function class III-IV (31.0%) (both P values < 0.05). The most common co-morbidities of AF were hypertension (49.2%), coronary heart disease (38.5%), diabetes mellitus (20.1%). Compared with patients of chronic AF, the patients of paroxysmal AF had higher success rates in amiodarone conversation and sinus rhythm maintenance after ablation (44.8% vs 29.9%, 87.5% vs 68.9%, P values < 0.05). Among the 1 310 inpatients, 992 patients (75.7%) received antithrombotic therapy. There were statistically significant differences in CHA2DS2 score and incidence rate of cerebral infarction among patients receiving aspirin, warfarin or rivaroxaban/other anticoagulation drugs [2(1, 3) vs 3(2, 4) vs 3(2, 5) and 6.3% vs 23.8% vs 30.2%, both P values < 0.05]., Conclusion: Our results of AF inpatients' age, gender, related disease distribution, AF types, incidence of stoke, therapeutic and epidemiological features are in accordance with the domestic and abroad reports.
