Acetylsalicylic Acid Resistance in Patients With Acute Coronary Syndrome and Its Relationship Between Mean Platelet Volume

Study design: Observational Study
Abstract: Objective: Insufficient biochemical response to Acetylsalicylic Acid (ASA) is defined as 'ASA resistance'. Its prevalence is unknown. The frequency of death and cardiovascular events rises as the mean platelet volume (MPV) increases in patients with acute coronary syndrome (ACS). Patients with high MPV are more resistant to antiplatelet agents. Our study aimed to evaluate the temporal variability of ASA resistance and platelet reactivity in ACS patients and to demonstrate its relationship with MPV. Material and Methods: Our study is single-center prospective, cross-sectional study. Patients over 18 years of age who were hospitalized due to ACS and underwent percutaneous coronary intervention were included. ASA resistance and MPV measurements were taken at admission and first month. The prevalence and alteration of ASA resistance and its relationship with MPV were analyzed. Results: 115 patients were included in the study. 7 patients (6.08%) were ASA-resistant at first admission and increased to 22 (19.13%) at the 1st month follow-up (p=0.003). A significant numerical increase in ASA resistance was observed in the first month of controls (p
