Objectives: To evaluate the safety of dual antiplatelet therapy in patients in whom long-term anticoagulation (AC) with warfarin is recommended. Background: It is well established that antiplatelet therapy with aspirin ad thienopiridines is required following percutaneous coronary intervention (PCI) with stent implantation. Some patients have also indication for long-term AC. The optimal antithrombotic strategy following PCI in such patients is unclear. Methods: All consecutive patients who underwent PCI with stent implantation discharged on triple therapy (defined as the combination of aspirin and thienopyridines and AC with warfarin) were analyzed. Results One-hundred and twenty-seven patients with 224 lesions: 86.6% males, mean age 69.9±8.8 years were included in the study. Drug-eluting stents (DES) were positioned in 71 (55.9%) and bare metal stent (BMS) in 53 (41.7%) patients. Atrial fibrillation (AF) was the main indication (59.1%) for AC treatment, followed by prosthetic valves (12.4%) and mural left ventricular (LV) thrombus (9.1%). Average risk of thromboembolic events in the subgroup with AF was 1.79 ± 1.23 according to CHADS2 score. The mean triple therapy duration was 5.6±4.6 and clinical follow-up 21.0±19.8 months. During the triple therapy period, 6 patients (4.7%) developed major bleeding complications; 67% of which occurred within the first month. No significant differences between DES and BMS were observed in the incidence of major (respectively 5.6% vs. 3.8%, p=1.0) and minor bleeding (respectively 1.4% vs. 3.8%, p=0.57) and mortality (respectively 5.6% vs. 1.9%, p=0.39). Four patients died in DES group: 3 of major bleeding complications and one of ischemic stroke. The only death in the BMS group was due to subarachnoid hemorrhage. A significant difference was observed in favor of DES in target vessel revascularization (14.1% vs. 28.3%, p=0.041). Conclusions: While on triple therapy, major bleeding complications occurred in 4.7% of patients, half of them were lethal and most (67%) occurred within the first month.

Management of patients on long-term anticoagulation requiring percutaneous coronary intervention is challenging. Triple therapy with oral anticoagulant and dual antiplatelet therapy is the standard of care. However, there is no strong evidence to support this strategy. There is emerging data regarding the safety and efficacy of dual therapy with oral anticoagulant and single antiplatelet therapy in these patients. In this comprehensive review we highlight available evidence regarding various antithrombotic regimens’ efficacy and safety in patient with coronary artery disease undergoing percutaneous coronary intervention with long-term anticoagulation therapy requirements.
