Acute cerebrovascular diseases are characterized by high incidence, high disability rate and high mortality rate. With the improvement of people’s living standard, its incidence is increasing year by year, and now it has become the three major killers of human health together with tumor and heart disease. According to epidemiological data, there are about 2 million new cerebrovascular patients, 1.5 million deaths, and 6-7 million disabled patients in China every year. Therefore, how to prevent cerebrovascular disease has become more and more important to the general public. Of course, to prevent the occurrence of a disease, the first thing is to find out the risk factors that lead to the occurrence of the disease, so as to be able to target. The risk factors of cerebrovascular diseases simply include two aspects: interferable factors (such as diabetes, hypertension, heart disease, etc.) and non-interferable factors (age, gender, genetics, etc.). To achieve the goal of preventing cerebrovascular disease, it is undoubtedly the most important to control the intervenable factors. Then we will briefly talk about how to prevent the occurrence of cerebrovascular disease: 1, regular monitoring of blood pressure levels, if there is hypertension, to actively control blood pressure through diet and drugs, general patients recommended to control blood pressure target of 140/90mmHg or less; combined diabetes or kidney disease patients target of 130/80mmHg or less; age greater than 85 years old or the presence of intracranial The target is 150/90mmHg or less in patients with intracranial stenosis. If coronary artery disease, arrhythmia or heart failure is present, actively consult a specialist for treatment of the primary cause to avoid cardiogenic stroke. 3. Regularly monitor blood glucose levels. If diabetes is present, make sure to control blood glucose levels within a reasonable range through diet, exercise and medication, as the risk of stroke in diabetic patients is 4 times higher than that in the general population. 4, prevention and control of dyslipidemia, hyperlipidemia is a risk factor for atherosclerosis, through control of diet and physical exercise supplemented by drug therapy to control dyslipidemia. 5. Quit smoking and drinking. Smoking and alcohol consumption are important risk factors for stroke. 6. Control body weight. Adult body mass index should be controlled within 28 (calculated as weight (KG)/height squared); or waist/hip circumference <1. A large number of clinical data suggest that the risk of cardiovascular disease is 2-3 times higher if the waist circumference exceeds the standard value. 7.Patients with diabetes and hyperlipidemia are recommended to have regular review of carotid ultrasound, and actively intervene if there is evidence of carotid artery stenosis. 8.Moderate physical exercise and reasonable diet. A light diet, low salt and low fat is recommended. Physical exercise of an intensity that can be tolerated by the individual for more than 30 minutes 2-3 times a week is recommended. 9, consult with a specialist, if there is no contraindication to antiplatelet drugs such as aspirin or clopidogrel, consider giving antiplatelet drugs orally according to the risk level as appropriate. As long as the above points can be achieved, the risk of cerebrovascular disease will be significantly reduced, while for people aged >45 years old, it is recommended that routine physical examination (blood routine, liver and kidney function, blood lipid and blood sugar, electrocardiogram, ultrasound, chest X-ray) every 6 months, once abnormalities are found, promptly seek medical attention.
