Introduction And Objectives: In the NASPEAF (National Study for Prevention of Embolism in Atrial Fibrillation) trial, combination therapy with an anticoagulant and an antiplatelet was more effective than anticoagulation alone in patients with atrial fibrillation. We report long-term follow-up in these patients, including prospective evaluation of different antiplatelet therapies.
Methods: This analysis included 574 atrial fibrillation patients.
Aims: Atrial fibrillation patients with prior embolism have a high risk of vascular events in spite of anticoagulant therapy and elderly patients carry an additional risk. We analysed and compared vascular events-rate between older and younger than 75 years atrial fibrillation patients randomized to anticoagulant-alone or combined antiplatelet plus moderate-level anticoagulant therapy.
Methods And Results: A total of 967 patients stratified by age and the history of prior embolism were randomized to therapeutic doses of anticoagulant-alone or combined antithrombotic therapy.
