The significance of establishing a primary prevention system for spontaneous cerebral hemorrhage: The third survey of causes of death by the Ministry of Health in 2008 showed that the death rate of stroke was 22.45%, surpassing that of malignant tumors by 22.32%, making it the first cause of death in China and the first cause of disability in adults. The World Health Organization (WHO) multi-country survey on the trends and determinants of cardiovascular disease showed that the recurrence rate of stroke in China is as high as 1/3, ranking first in the world. According to the study, cerebrovascular disease is significantly higher in Asia than in Europe and the United States, and the incidence of cerebrovascular disease in China ranks first in the world, with about two million people suffering from the disease every year, and hypertensive cerebral hemorrhage is particularly serious, and if not treated in time, about half of them die within 24 hours. At present, cerebrovascular disease has become the main disease that endangers the health and life of middle-aged and elderly people in China. In urban areas, cerebrovascular disease deaths have risen to the first and second place, and in rural areas, cerebrovascular disease deaths ranked third in the early 1990s and rose to second place in the late 1990s. The number of patients who survive (including those who have recovered) is 6-7 million, leaving different degrees of disability, which seriously affects life and work. According to a survey in six cities in China, the prevalence of cerebral hemorrhage is 112/100,000 people, and the annual incidence rate is 81/100,000 people, and there is a trend of younger people with cerebral hemorrhage in recent years. What is more important to pay attention to is that the national annual expenditure for this disease is close to 20 billion RMB, causing a heavy economic burden to the country and many families. Reducing the occurrence of hypertensive cerebral hemorrhage has become a global concern and a direction for health system research. Hypertension is the most important controllable risk factor for cerebral hemorrhage. When blood pressure >115/75mmHg, the incidence and mortality of cerebral hemorrhage will increase significantly regardless of the increase of systolic or diastolic blood pressure. Our study shows that 79.7% of strokes in China can be attributed to hypertension. Therefore, controlling hypertension is still an important indicator to prevent cerebral hemorrhage. The prevalence of hypertension in China is 10% to 20%, and there are about 100 million patients nationwide. On average, one out of every five adults in the north is hypertensive; one out of every 10 adults in the south and remote areas is hypertensive. In the survey, it was found that the awareness of hypertension is 36.2% in urban areas and 5.4% in rural areas, totaling 12%; the rate of taking medication is 17.4% in urban areas and 5.4% in rural areas, totaling 12. 2%. Improved control of hypertension is an important step in preventing cerebral hemorrhage. Dyslipidemia is the second most common risk factor, with dyslipidemia leading to 11.9%-42% of cerebrovascular disease. Overweight becomes another common risk factor for cerebral hemorrhage. Obese people have varying degrees of endocrine disorders, high blood lipids and high cholesterol. The prevalence of obese people with hypertension is 2.9 times higher than that of normal weight. In this state, the renin-angiotensin system of the vascular wall is hyperfunctional, leading to increased vascular tone and damage to the endothelial function. It is well known that most of the causes of obesity are related to excess nutrition, and controlling excessive nutritional intake has become one of the important methods to prevent obesity, hypertension and hyperlipidemia. In summary, hypertension, dyslipidemia and obesity become the most dangerous factors of cerebrovascular disease, and how to systematically prevent the occurrence of cerebral hemorrhage has become the research focus of this project.
