Outline of Final Research Achievements

The current in vivo study demonstrated that Direct Oral AntiCoagulant (DOAC), clinically used for prevention of cardioembolism from nonvalvular atrial fibrillation, is effective in accelerating recirculation and in reducing the size of cerebral infarction. Clinically cases treated with DOACs not only have less cerebral infarction but also smaller size and lighter sequels. The current data proved the pathophysiology.
