A Real World Data of Dabigatran Etexilate: Multicenter Registry of Oral Anticoagulants in Nonvalvular Atrial Fibrillation

Atrial fibrillation (AF) is a common cardiac arrhythmia. Dabigatran etixalate (DE) is one of the new oral anticoagulant drugs being used in nonvalvular AF (NVAF). There is no adequate real world data in different populations about DE. The aim of this registry was to evaluate the efficacy and safety of DE Consecutive NVAF patients treated with warfarin or both DE doses were enrolled during 18 months study period. The patients were re-evaluated at regular 6-month intervals during the follow-up period. During the follow-up period outcomes were documented according to RELY methodology A total of 555 patients were analyzed. There was no significant difference in ischemic stroke rates (p = 0.73), death rates (p = 0.15) and MI rates (p = 0.56) between groups. The rate of major bleeding was significantly higher in warfarin and dabigatran 150 mg group than dabigatran 110 mg (p < 0.001). Intracranial bleeding rate and relative risk were significantly lower in dabigatran 110 mg group than warfarin group (p = 0.004). Dyspepsia was significantly higher in both DE doses than warfarin (p = 0.004) Both DE doses are as effective as warfarin in reducing stroke rates in NVAF patients, without increasing MI rates. Intracranial bleeding rates are significantly lower in warfarin than both doses of DE and gastrointestinal bleeding risk increases with increased DE doses.
