Brief Summary:
This study will evaluate whether a gene marker can improve the identification of atrial fibrillation in patients with ischemic stroke, and evaluate whether the decision to anticoagulate could be improved by a marker of atrial fibrillation.
Detailed Description:
Atrial fibrillation (AF) is a major cause of ischemic stroke that is critical to identify because anticoagulation provides a 66% risk reduction in recurrent stroke. However, opportunities to prevent stroke due to AF are frequently missed because AF is paroxysmal and therefore not detected at the time of stroke. In addition, even when AF is identified anticoagulation may not be initiated due to perceived contraindications.
This study will (1) evaluate whether a gene marker can improve the identification of AF in patients with ischemic stroke, and (2) evaluate decisions by health care provider and patients to anticoagulate AF, and whether this decision could be improved by a marker of AF at time of stroke. An AF Gene Score will be developed comprised of genes associated with inflammatory and thrombotic pathways related to risk of AF thromboembolism in stroke patients with AF. The AF Gene Score measured at time of stroke can stroke will permits rapid identification of stroke due to AF which may increase initiation of anticoagulation therapy. This is important in cryptogenic stroke, where prolonged monitoring leaves uncertainty regarding the association of delayed AF with initial stroke and delays anticoagulation.
