Thromboembolic risk was assessed using the CHA₂DS₂-VASc score including congestive heart failure, hypertension, age ≥75 years, diabetes, stroke/transient ischemic attack (TIA)/thromboembolic event, vascular disease, age 65–74 years, female gender.

The risk of bleeding was assessed on the basis of the HAS-BLED score including arterial hypertension, abnormal kidney/liver function, stroke, bleeding predisposition, unstable INR (international normalized ratio), the elderly (>65 years old), drug/alcohol consumption [11].
