Abstract

Hemostatic abnormalities mainly decreased blood flow and increased stasis, and platelet hyper-aggregation increase thrombotic risk subsequent atrial fibrillation (AF) episodes. Excess elevation of extracellular glycoprotein thrombospondin 1 (TSP1) in circulation has emerged to predict prognosis of ischemic stroke. Moreover, TSP1 is found strongly associated with platelet hyper-aggregability and impaired nitric oxide response, through its cognate receptor CD47, thus exacerbating ischemic progression in AF patients. TSP1 arises as a prospective target of our candidate medicine.
