Stroke is the fifth leading cause of death in the United States and the leading cause of disability. However, in China, stroke is one of the most frequent causes of death and chronic disability. Ischemic strokes in adults younger than 45 years of age were regarded as a relatively uncommon event in the proportion of <5% of all ischemic strokes.

Currently, stroke is the fifth leading cause of death in the United States and the leading cause of disability. However, in China, stroke is one of the most frequent causes of death and chronic disability. Ischemic strokes in adults younger than 45 years of age were regarded as a relatively uncommon event in the proportion of <5% of all ischemic strokes. Our study aimed to evaluate some Biomarkers Underlying in Ischemic Stroke in Chinese Young Adults.
