Real-life anticoagulation treatment of atrial fibrillation after catheter ablation: Possible overtreatment of low-risk patients.

摘要: Catheter ablation provides curative treatment for atrial fibrillation (AF). Data on anticoagulation after the procedure are sparse. We investigated real-life antithrombotic AF and examined its adherence to current recommendations. Eight hundred forty-four patients (age 58 ±10 years) underwent ablation. Most had a CHADS2 score of 0 (46%) or 1 (45%). Seven-day Holter was performed at three, six 12 months Decision made by general practitioners referring cardiologists in consultation with patients. At discharge, anticoagulants were prescribed vast majority (94–96%) This percentage remained high three (80–90%) without differences between stroke risk groups. months, use mainly influenced detection recurrence; usage exceeded 90% all groups recurrences. In recurrences, significant but small, ranging from 42% (CHADS2=0) 62% (CHADS2≥2) (p=0.033). multivariate analysis, only factor independently associated oral recurrences (odds ratio=16.2, p<0.001), whereas effect not (p=0.080). The other factors also significant. Contrary recommendations, is hardly guided profile remains even low-risk most important influencing during follow-up. results possible overtreatment
