ABSTRACT
Cerebrovascular disease has caused serious harm to the health and life of the population in China. The current epidemic situation of stroke in China is still at its peak and it causes a huge burden of disease. According to the current situation, the most effective way to reduce the damage and burden of cerebrovascular disease is to strengthen primary prevention before the first onset of stroke, which is promoting actively intervention on the risk factors of cerebrovascular disease to reduce the incidence of stroke in the population.
