Assess the risk of stroke and bleeding in your non-valvular AF patients

Assess the Risk of Stroke and Bleeding in your
Non-valvular AF Patients


The ESC guidelines recommend to assess the risks of stroke and bleeding in the decision-making process for thromboprophylaxis in patients with non-valvular AF by using the CHA2DS2-VASc and HAS-BLED scores, respectively.

Stroke Risk Assessment

CHA2DS2-VASc is a risk assessment system developed by Lip et al., which refines the older CHADS2 score by including additional stroke risk factors and putting greater emphasis on age as a risk factor.1,2

Bleeding Risk Assessment

HAS-BLED was developed as a practical risk score to estimate the 1-year risk for major bleeding in patients with AF taking vitamin K antagonist (VKA).3

Assess the risk of stroke & bleeding of your non-valvular AF patients with the stroke-bleed risk calculator

The Boston Scientific Stroke-Bleed Risks Calculator will help you easily balance the risk of stroke against the risk of bleeding prior to deciding the best treatment option for your AF patients; consider LAAC therapy for your AF patients who are at high risk of stroke and bleeding.
