Aspirin is one of the most commonly used drugs to prevent cardiovascular diseases in our country. However, whether aspirin is used in primary prevention within the appropriate indication has not been adequately studied. The aim of this study is to investigate prescription distribution and appropriate use of aspirin in primary prevention according to international guidelines. The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study is from all regions of Turkey and provided data from 14 different cities in 30 different cardiology clinics. It has been designed as a multicenter, cross-sectional study. Patients over the age of 18, who applied to the cardiology outpatient clinic, and who regularly use low-dose aspirin (75-100 mg) in the last 30 days for any reason, were included in the study. Patients, who use aspirin for secondary prevention, were excluded for this analysis and the appropriateness of aspirin use was evaluated according to the 2016 European Society of Cardiology (ESC) and 2019 American College of Cardiology/American Heart Association (ACC/AHA) guidelines. Inappropriate aspirin use for primary prevention was detected in 100% of patients according to the 2016 ESC guidelines and in 89% of patients according to the 2019 ACC/AHA guidelines. In our country, inappropriate aspirin use is common in primary prevention according to the ESC guidelines and ACC/AHA guidelines.
