Abstract Objective To estimate the prevalence and current status of anticoagulation therapy of atrial fibrillation (AF) among the population aged ≥60 years old in a community of Pudong New Area, Shanghai, and to provide evidences for community management and intervention of AF. Methods In a cluster sampling method, the prevalence of AF among the population aged 60 and above in the community were surveyed; AF was screened and diagnosed by electrocardiogram. The general information, past medical history, laboratory indicators and medication of patients with AF were collected. Results A total of 8 739 residents aged 60 and above are included in the final analysis; 178 patients with AF are detected with a morbidity rate of 2.04%, among whom are 168 cases (94.38%) with non-valvular AF. Patients with AF are at an average age of (74.1±7.8) years old of whom 102 cases (57.30%) are males. The top three comorbidities are separately hypertension (84.3%), diabetes (39.3%), and coronary heart disease (25.8%). Among the 178 patients with AF, the anticoagulation rate is 39.33% while 21.91% receive antiplatelet therapy, and 38.76% fail to receive antithrombotic therapy. The average HAS-BLED bleedingrisk prediction score is (2.73±0.91); the score of males is lower than that of females[(2.60±0.81) vs. (2.91±1.01), P<0.05]. The CHA2DS2-VASc score of patients with non-valvular AF is (3.92±1.68); the score of males is also lower than that of females [(3.33±1.50) vs. (4.74±1.57), P<0.01]. Conclusion The morbidity rate of AF in the participants aged ≥60 years old in the community is relatively high with old average age, and the overall risk of stroke is high, however, the anticoagulation rate of AF is low. It is urgent to strengthen community management, and propaganda and education of AF.
