Sudden loss of neurological function is the hallmark of CVD. Cerebrovascular accident or stroke may be defined as a sudden interruption of blood supply by embolism or thrombosis, or hemorrhage into the brain. Epidemiological investigation The first leading cause of death in China About 2 million/per year in China Hospitalization cost 9 billion annually According to WHO prediction, the stroke incidence in China increases by 9% annually.
