Background. Over the last years, the use of oral anticoagulant treatment (OAT) has increased dramatically, principally for the prevention of embolic stroke in patients with atrial fibrillation. This study was aimed at evaluating the efficacy and safety of the management of OAT in a real-practice situation. Methods. Nine hundred and three consecutive unselected patients, 250 of whom with atrial fibrillation, referred for the control of OAT to the Anticoagulation Clinic of the University of Florence were studied. The total follow-up period was 1679 patient-years. Results. The rate of major bleeding events was 0.8 per 100 patient-years in atrial fibrillation patients. In patients with a target INR; ≥ 3 a significantly higher rate of bleeding (p = 0.02) with respect to patients with a target INR <3 was observed. Conclusions. A low incidence of complications may be obtained even in elderly atrial fibrillation patients on OAT followed in an Anticoagulation Clinic specifically devoted to this management.
