| Aims This study is a real world, observational study evaluating the treatment persistence of oral antiplatelet (OAP) therapy during a one-year follow-up in patients after an acute coronary syndrome (ACS). Methods and results Data on diagnosis, comorbidities, follow-up, OAP treatment, reasons, and decision maker for treatment discontinuation in patients who were discharged from a hospital in Belgium after an ACS between 1 July 2012 and 1 June 2013 were collected by cardiologists from 18 centres, up to 360 days from discharge. Out of the 671 patients surveyed, 295 patients were included in the persistence analysis. The remainder was excluded from the analysis due to the lack of precise information on OAP stopping date. The proportion of patients still using OAPs after 90, 180, 270, and 360 days was 92, 89, 83, and 73%, respectively. OAP persistence was higher for patients treated with prasugrel or ticagrelor. At 360 days, 79% of patients with a ST-segment elevation myocardial infarction (STEMI) and 66% of patients with a non-STEMI were still adhering to the prescribed course of treatment. Among the 79 patients with early treatment discontinuation, the mean treatment duration was 197.0 +/- 125.18 days. The main decision taker in premature treatment cessation was the cardiologist (31% of cases), while the most frequently cited reasons included surgery (25%) and perceived high bleeding risk (19%). Conclusion Treatment persistence with OAPs after ACS in Belgium is high throughout the recommended period. Discontinuation was observed more often in patients treated with clopidogrel and was mainly initiated by the cardiologist. |
