Abstract

Current recommendations for the antithrombotic management of patients receiving oral anticoagulation (OAC) who undergo percutaneous coronary intervention with stent implantation (PCI-S) are based on limited and relatively weak data. To broaden and strengthen available evidence, the management and 1-year outcomes of OAC patients who underwent PCI-S and were included in a prospective, multicenter registry from 2003 to 2007 were evaluated. Among the 632 patients receiving OAC, mostly because of atrial fibrillation (58%), who underwent PCI-S, mostly because of acute coronary syndromes (63%), dual-antiplatelet therapy with aspirin and clopidogrel was the most frequently prescribed at discharge (48%), followed by triple therapy with OAC, aspirin, and clopidogrel (32%) and OAC plus aspirin (18%). The choice of antithrombotic therapy largely matched the thromboembolic risk profiles of patients, with the prescription of regimens including OAC predicted by the presence of non-low-risk features. The cumulative 1-year occurrence of major adverse cardiovascular events was as high as 27% and was not significantly different among the 3 treatment groups. Stroke and stent thrombosis were limited to 2% and 3%, respectively, and although no significant differences were found among the 3 groups, stroke was 4 times less frequent when OAC, with either 1 or 2 antiplatelet agents, was administered. Major bleeding was also limited to 3%, with no significant differences among the 3 groups. In conclusion, these findings suggest overall real-world management of OAC patients who undergo PCI-S that is in accordance with their clinical risk profiles and give further support to the reported efficacy and safety of triple therapy for the optimal treatment of these patients. © 2012 Elsevier Inc.
