Figures show that stroke is the first cause of death in China, the economic burden to China is up to 40 billion yuan per year and the prevalence is on the rise, urban than rural areas. China has already entered an aging society, if a large number of middle-aged people die prematurely or become disabled due to stroke, if not controlled, the first chronic disease in China may be a “blowout” or even a “tsunami”, so it is urgent to screen and intervene in the risk of stroke in middle-aged people. There is no time to lose. The report points out that the results of the big data analysis of stroke screening for high-risk groups show stable patterns and characteristics: 1. 4. The prevalence of major risk factors in the population shows that smoking, dyslipidemia, hypertension, significant overweight and obesity are the most prevalent in men. 5. In terms of the age distribution of risk factors, the detection rate of dyslipidemia, overweight and obesity in middle-aged people has been comparable to that of the elderly, while the smoking rate of middle-aged men is much higher than that of the elderly, which, together with the high work pressure, heavy family burden and less participation in physical exercise of middle-aged people, has led to the trend of younger stroke. Successful experience at home and abroad shows that control of stroke risk factors and standardized treatment can effectively reduce its morbidity, mortality, recurrence and disability rates. The report also points out that in the future, China still needs to strengthen and continue to promote stroke prevention and treatment projects, gradually establish a network system for prevention and treatment of cardiovascular and cerebrovascular diseases, actively implement prevention-oriented, multidisciplinary cooperation, regional linkage, graded treatment of chronic diseases and other prevention and control models, improve the collaborative service information and data platform, actively carry out stroke public welfare charity activities, significantly increase the public awareness of risk factors, and initially form a combination of prevention and treatment of health The initial formation of a long-term health management mechanism that combines prevention and treatment.
