Predictive Value of Infarction Volume on Hemorrhagic Transformation in Ischemic Stroke/TIA With Non-valve Atrial Fibrillation(NVAF) Patients Using Rivaroxaban

Second Affiliated Hospital, School of Medicine, Zhejiang University400 enrolled

Overview

This study was aimed at patients with newly diagnosed stroke / TIA associated with nonvalvular atrial fibrillation. We will observe the effect of early using rivaroxaban anticoagulation on hemorrhagic transformation, and explore the predictive value of multi-mode MRI infarct volume / MMP-9 on hemorrhagic transformation after anticoagulation therapy.
