|Congestive Heart Failure||1|
|Age ≥ 75 years||2|
|Age between 65 and 74 years||1|
|Vascular disease (previous MI, peripheral arterial disease or aortic plaque)||1|
Before bleeding risk evaluated score of 0 recommends no antithrombotic therapy and 2 or more antithrombotic therapy. A score of 1 recommends either antithrombotic or antiplatelet therapy. Consider a risk of bleeding assessment such as the HAS-BLED score before anticoagulation.
Developed on the same principles as the CHADS2 score it considers additional stroke risk factors and gives age a higher weighing. This results in better discrimination between high and low risk patients.
