Abstract：Objective To analyze the clinical status of patients with atrial fibrillation(AF) in hospital. Methods Clinical data of 1 326 AF patients admitted to Second Hospital of Shanxi Medical University from January 2016 to January 2018 were retrospectively reviewed. Demographic data,concomitant diseases and cardiovascular risk factors,therapeutic and antithrombotic options were analyzed. Results The mean age of the 1 326 patients was (68 ± 13) years; patients of 70-79 years old took the largest percentage [31.4％(416 /1 326) ]. There was no significant difference between the composition ratio of males and females(712 cases vs 614 cases) (P > 0.05). Among the cardiovascular risk factors,536 patients(40.4％) had hypertension and 107 patients (8.1％) had sleep apnea syndrome. In patients with heart failure and cerebral stoke /transient ischemic attack, chronic atrial fibrillation accounted for a higher percentage than paroxysmal atrial fibrillation (P < 0.01 ). In patients with coronary atherosclerotic heart disease(CHD) ,paroxysmal atrial fibrillation accounted for a higher percentage than chronic atrial fibrillation(P < 0.01). Most patients were treated with medication,only 141 patients (10.6％) had radiofrequency ablation and 2 patients (0.2％) had left atrial appendage occlusion. Ratios of non-antithrombotic treatment,antiplatelet treatment and warfarin treatment were 18.3％(243) ,54.1％(717) and 21.1％(280); the standard rate of international normalized ratio after taking warfarin was 47.1％ (132 /280). Conclusions Elderly patients (70-79 years old) take the majority of atrial fibrillation in our hospital and there is no significant difference between gender. Hypertension,heart failure and CHD are the main risk factors associated with atrial fibrillation. Patients with sleep apnea syndrome should be paid attention. Drug treatment is the main therapeutic choice and the rate of radiofrequency ablation is low. Receptance of antithrombotic therapy is low and the effect is unsatisfactory.
