- Abstract
Background: Whether ticagrelor may reduce periprocedural myocardial necrosis after elective percutaneous coronary intervention (PCI) in patients with and without chronic clopidogrel therapy is unclear., Objectives: This study sought to compare ticagrelor vs clopidogrel in patients with and without chronic clopidogrel therapy before undergoing elective PCI., Methods: In this prespecified analysis of the ALPHEUS (Assessment of Loading With the P2Y12 Inhibitor Ticagrelor or Clopidogrel to Halt Ischemic Events in Patients Undergoing Elective Coronary Stenting) trial, patients were defined as clopidogrel(+) and clopidogrel(-) according to the presence and absence of clopidogrel treatment for ≥7 days before PCI, respectively. The primary endpoint was the composite of PCI-related myocardial infarction and major injury as defined by the third and fourth universal definition 48 hours after PCI., Results: A total of 1,882 patients were included, 805 (42.7%) of whom were clopidogrel(+). These patients were older, had more comorbidities, and had more frequent features of complex PCI. The primary endpoint was less frequently present in clopidogrel(-) compared to clopidogrel(+) patients (32.8% vs 40.0%; OR: 0.73; 95% CI: 0.60-0.88), but no significant differences were reported for the risk of death, myocardial infarction, stroke, or transient ischemic attack at 48 hours or 30 days. Ticagrelor did not reduce periprocedural myocardial necrosis or the risk of adverse outcomes, and there was no significant interaction regarding the presence of chronic clopidogrel treatment., Conclusions: Clopidogrel-naive patients presented less periprocedural complications compared to clopidogrel(+) patients, a difference related to a lower risk profile and less complex PCI. The absence of clopidogrel at baseline did not affect the absence of a difference between ticagrelor and clopidogrel in terms of PCI-related complications supporting the use of clopidogrel as the standard of care in elective PCI in patients with or without chronic clopidogrel treatment., Competing Interests: Funding Support and Author Disclosures This trial was led by the Allies in Cardiovascular Trials Initiatives and Organized Networks (ACTION) Study Group, an Academic Research Organization based at Pitié-Salpêtrière Hospital in Paris, France. It was sponsored by Assistance Publique-Hôpitaux de Paris and was funded by an unrestricted grant from AstraZeneca. AstraZeneca was not involved in the data collection, analysis, or in the writing of the manuscript. The Steering Committee oversaw the conduct of the trial in collaboration with representatives of the study sponsor. The trial was monitored by an independent Data and Safety Monitoring Board. Data were collected and analyzed according to the predefined statistical analysis plan by academic statisticians of the ACTION group. Drs Silvain and Montalescot had full access to the data and final responsibility for the decision to submit for publication. There was no medical writing support.
