HAS-BLED score as a reference point for risk stratification

Atrial fibrillation (AFib) is a common cardiac arrhythmia and increases the risk of suffering a stroke. According to the current ESC guideline, patients with VHF without a clear contraindication should not be withheld oral anticoagulation. The _CHA2DS2-VASc score can be used to estimate the risk of stroke. The HAS-BLED score has proven useful for risk stratification with regard to bleeding complications. Several recent randomized studies have investigated the situation in patients with device-detected atrial fibrillation.
