RESUMO
Diagnostic and treatment strategies for acute coronary syndrome have improved dramatically over the past few decades, but mortality and recurrent myocardial infarction rates remain high. An aging population with increasing co-morbidities heralds new clinical challenges. Therefore, in order to evaluate and improve current treatment strategies, detailed information on clinical presentation, treatment and follow-up in real-world patients is needed. The Future Optimal Research and Care Evaluation in patients with Acute Coronary Syndrome (FORCE-ACS) registry (ClinicalTrials.gov Identifier: NCT03823547) is a multi-center, prospective real-world registry of patients admitted with (suspected) acute coronary syndrome. Both non-interventional and interventional cardiac centers in different regions of the Netherlands are currently participating. Patients are treated according to local protocols, enabling the evaluation of different diagnostic and treatment strategies used in daily practice. Data collection is performed using electronic medical records and quality-of-life questionnaires, which are sent 1, 12, 24 and 36 months after initial admission. Major end points are all-cause mortality, myocardial infarction, stent thrombosis, stroke, revascularization and all bleeding requiring medical attention. Invasive therapy, antithrombotic therapy including patient-tailored strategies, such as the use of risk scores, pharmacogenetic guided antiplatelet therapy and patient reported outcome measures are monitored. The FORCE-ACS registry provides insight into numerous aspects of the (quality of) care for acute coronary syndrome patients.
RESUMO
PURPOSE: The POPular Risk Score was developed for the selective intensification of P2Y12 inhibitor treatment with prasugrel instead of clopidogrel in patients undergoing non-urgent percutaneous coronary intervention (PCI) with stent implantation. This score is based on platelet reactivity (VerifyNow P2Y12 assay), CYP2C19 genotyping, and clinical risk factors. Our aim was to determine if the use of this score in clinical practice is associated with a reduction in thrombotic events without increasing bleeding events. METHODS: In a single-center prospective cohort study, patients with a high risk score were treated with prasugrel and patients with a low risk score with clopidogrel. The risk score-guided cohort was compared with a historic cohort of clopidogrel-treated patients. The endpoint consisted of all-cause death, myocardial infarction, stroke, or stent thrombosis during 1 year of follow-up. TIMI major and minor bleeding events were also analyzed. RESULTS: The guided cohort contained 1127 patients, 26.9% of whom were switched to prasugrel according to the POPular Risk Score. The historic cohort contained 893 patients. The incidence of the combined thrombotic endpoint was significantly lower in the guided cohort as compared with the historic cohort (8.4% versus 3.7%, p < 0.001). This strategy was safe with respect to bleeding (4.0% versus 1.3%, p < 0.001, for TIMI major or minor bleeding). Results were comparable after multivariate and propensity score matched and weighted analysis. CONCLUSION: Selective intensification of P2Y12 inhibitor treatment after non-urgent PCI based on the POPular Risk Score is associated with a reduction in thrombotic events without an increase in bleeding events.
