Dabigatran in secondary stroke prevention: clinical experience with 106 patients.

Introduction: Our aim was to analyze our clinical experience with dabigatran etexilate in secondary stroke prevention.
Methods: We retrospectively included patients starting dabigatran etexilate for secondary stroke prevention from March 2010 to December 2012. Efficacy and safety variables were registered.
Results: 106 patients were included, median follow-up of 12 months (range 1-31). Fifty-six females (52.8%), mean age 76.4 (range 50-95, SD 9.8), median CHADS2 4 (range 2-6), CHA2DS2-VASc 5 (range 2-9), and HAS-BLED 2 (range 1-5). Indication for dabigatran etexilate was ischemic stroke in 101 patients and acute cerebral hemorrhage (CH) due to warfarin in 5 (4.7%). Dabigatran etexilate 110 mg bid was prescribed in 71 cases (67%) and 150 mg bid was prescribed in the remaining. Seventeen patients (16%) suffered 20 complications during follow-up. Ischemic complications (10) were 6 transient ischemic attacks (TIA), 3 ischemic strokes, and 1 acute coronary syndrome. Hemorrhagic complications (10) were CH (1), gastrointestinal bleeding (6), mild hematuria (2), and mild metrorrhagia (1), leading to dabigatran etexilate discontinuation in 3 patients. Patients with previous CH remained uneventful. Three patients died (pneumonia, congestive heart failure, and acute cholecystitis) and 9 were lost during follow-up.
Conclusions: Dabigatran etexilate was safe and effective in secondary stroke prevention in clinical practice, including a small number of patients with previous history of CH.
