What are the TOAST criteria for classifying ischemic stroke subtypes?
The TOAST criteria (Trial of Org 10172 in Acute Stroke Treatment) is a system used to classify ischemic stroke subtypes. It includes five categories: large-artery atherosclerosis, cardioembolism, small-vessel occlusion, stroke of other determined etiology, and stroke of undetermined etiology. The criteria are based on clinical information, laboratory studies, and imaging data. Additionally, they are used to assess the risk of recurrent stroke and long-term survival in ischemic stroke subtypes.
