Conclusions
To the best of our knowledge, the ASSOS study cohort represents the largest number of patients treated with aspirin in Turkey. The present study provides contemporary data on aspirin use both in primary prevention and secondary prevention group patients. The results of our study suggest that the overuse of aspirin is common because of physicians’ poor compliance with the guideline recommendations in patients without documented CVD. Female patients who were on oral anticoagulants and had heart failure were at the highest risk for inappropriate use of aspirin however, older age, smoking, hypertension, diabetes mellitus were associated with appropriate use of aspirin. Thus, a greater emphasis should be given to these patients’ characteristics.
