Safety and efficacy of aspirin, clopidogrel, and warfarin after coronary stent placement in patients with an indication for anticoagulation

Dual antiplatelet therapy with aspirin and clopidogrel has replaced aspirin and systemic anticoagulation with warfarin as the preferred antithrombotic therapy after percutaneous coronary intervention (PCI) with stent placement. However, a number of patients have indications for all 3 drugs. We sough...

description Dual antiplatelet therapy with aspirin and clopidogrel has replaced aspirin and systemic anticoagulation with warfarin as the preferred antithrombotic therapy after percutaneous coronary intervention (PCI) with stent placement. However, a number of patients have indications for all 3 drugs. We sought to determine the frequency and type of hemorrhagic complications in patients who undergo systemic anticoagulation with warfarin while receiving aspirin and clopidogrel after a PCI with stent placement. We performed a retrospective analysis of the Mayo Clinic PCI database and identified 66 consecutive patients who were discharged from hospital after PCI between January 2000 and August 2002 (inclusive) receiving a combination of dual antiplatelet therapy (aspirin and clopidogrel) and systemic anticoagulation (warfarin) to determine the incidence of bleeding and other clinical events during the treatment period. Six patients (9.2%; 95% CI, 3.5–19.0) reported a bleeding event; 2 patients required a blood transfusion. No patient died or sustained a myocardial infarction or stent thrombosis. The risk of bleeding may be increased in patients treated with aspirin, a thienopyridine, and warfarin early after PCI with stent placement.
