Appropriate Use of Aspirin in the Primary Prevention Group
Aspirin use was inappropriate in all primary prevention patients according to ESC guidelines. Of the primary prevention patients whose ages were between 40-70 years, 324 were at high (≥10%) ASCVD risk and low bleeding risk (HASBLED≤ 2) whereas 52 were at high (≥10%) ASCVD risk and high bleeding (HASBLED>2) risk (Fig 2 ). Therefore, 808 of the 1132 patients (71 %) accepted as inappropriate use of aspirin according to the USPTF guidelines. Univariate analysis showed being female, older age, smoking, educational status (illiterate), having hypertension, atrial fibrillation, heart failure, hyperlipidemia, diabetes mellitus, major bleeding history and being on OAC therapy were associated with inappropriate use of aspirin (Table 2 ). Multivariate analysis was performed to find independent predictors of inappropriate use of aspirin in primary prevention patients. Female sex, oral anticoagulant use and heart failure were independent predictors of inappropriate aspirin use. However older age, smoking, hypertension, diabetes mellitus were associated with appropriate of aspirin use (Table 3 ).
