[Long-Term Therapy With Indirect Anticoagulants in Patients With Nonvalvular Atrial Fibrillation (Prospective Follow-Up Study). Part II. Effectiveness and Safety].
OBJECTIVE
To assess efficacy and safety of long-term international normalized ratio (INR) guided therapy with acenocoumarol in patients with nonvalvular atrial fibrillation.


METHODS
Patients (n=100) with nonvalvular atrial fibrillation and at least 1 risk factor of thromboembolic complications.


METHODS
Ischemic strokes, episodes of systemic thromboembolism and hemorrhagic complications were registered during 3 years of treatment with acenocoumarol (target INR 2.0-3.0).


RESULTS
Annual rates of ischemic strokes, hemorrhagic complications and major bleeding were 0.7, 14.4 and 1.1%, respectively. No episodes of thromboembolism were registered in patients with history of thromboembolic complications. Basing on data collected predictors of bleeding complications in patients with atrial fibrillation during long term treatment with acenocoumarol were elucidated.
