Survey on aspirin application for secondary prevention of coronary artery disease in Beijing communities

Abstract

Objective To survey the status of aspirin application asantiplatelet therapy for secondary prevention of coronary artery disease (CAD) in Beijing communities. Methods A cross-sectional survey on status of aspirin use was conducted among 60 communities in Beijing from September 2014 to January 2015. Items of survey included the duration of aspirin application, aspirin dosage, application time, reasons for interruption and reasons for non-application. Results Total 61 000 questionnaires were delivered and 56 969 valid ones were retrieved with a recovery of 93.39%. The aspirin application rate was 78.22% (15 105/19 311) among patients with diagnosed CAD, while that was 81.42% (1 319/1 620) among patients with self-reported CAD (χ2=9.06, P<0.01). There was no effect of early cardiovascular disease family history on aspirin application among patients with diagnosed CAD (P=0.77). Among the patients with diagnosed CAD, the reasons of no aspirin application were: rejection with unknown reasons, worry about stomach side effects, clopidogrel application, not suitable subjectsand other antiplatelet drugs application. Conclusions The proportion of aspirin application is relatively high among coronary artery disease patients in Beijing communities. The results of survey provide the direction of patient education in the future. Key words: Coronary artery disease; Aspirin; Community health center
