Antiplatelet treatment in acute coronary syndrome patients: Real-world data from the START-Antiplatelet Italian Registry
2019
BACKGROUND: Despite great advances with the introduction of ticagrelor and prasugrel in the treatment of acute coronary syndromes (ACS), the risk of thrombosis and bleeding remains significant and affects the choice of clinicians in the treatment of the single patient. Large registries are effective tools to explore patterns of drug administration and adherence to guideline recommendations in real-world clinical practice. METHODS: START- antiplatelet is a prospective, observational registry carried out by seven Italian cardiology institutions on patients admitted for ACS aimed to document the real world treatment of ACS patients, adding also data on 12-month follow-up. We present data on the first 1050 patients who have completed 1-year follow-up on a total of 1537 patients. Primary end-points were: 1) MACCE (Major Adverse Cardiovascular and Cerebrovascular Events) including all-cause and cardiovascular mortality, non fatal MI, urgent revascularization, TIA and ischemic stroke; 2) Major and minor bleeding according to TIMI, GUSTO and ISTH classifications. RESULTS: The dual antiplatelet treatment most prescribed was aspirin plus ticagrelor (47.9%) and aspirin plus clopidogrel (32.1%). At a mean follow-up was 335±131 days, both ticagrelor and prasugrel are associated with a statistically significant reduced total and cardiovascular mortality. Both prasugrel and ticagrelor do not show a significant increased incidence of major and minor bleedings with respect to clopidogrel. Patients with monotherapy had significantly higher incidence of both ischemic stroke and major bleedings. DISCUSSION: The analysis of the register has documented that both ticagrelor and prasugrel are associated with a statistically significant reduced total and cardiovascular mortality but both do not show a significant increased incidence of major and minor bleedings with respect to clopidogrel.
