Vascular disease itself and hypertension are more important causes of cerebral hemorrhage. If you have hypertensive patients, you should quit smoking and limit alcohol in your lifestyle, and the risk of cerebral hemorrhage will be reduced. Prevention of cerebral infarction is clinically called primary prevention, primary prevention for the following points: 1, change lifestyle, quit smoking and limit alcohol, and promote the Mediterranean diet; 2, to appropriate exercise, it is recommended that 3-5 days a week regular exercise 30-40 minutes, moderate intensity exercise is more reasonable; 3, for risk factors, three high that is, hypertension, diabetes and hyperlipidemia; now for five high, hypertension, diabetes, hyperlipidemia, plus high homocysteinemia and hyperuricemia, if these three risk factors or one of the five risk factors appear, the risk factors must be controlled and the symptoms must be treated, controlling the risk factors, improving the lifestyle, and doing proper exercise will play a vital role in the prevention of cerebral infarction. Cerebral hemorrhage and cerebral infarction are the two most common diseases of cerebrovascular disease, with cerebral infarction accounting for 85% of all cerebrovascular diseases and cerebral hemorrhage accounting for 15% of all cerebrovascular diseases. If we want to prevent both cerebral hemorrhage and cerebral infarction, the key is hypertension, which can cause both cerebral infarction and cerebral hemorrhage. Therefore, it is necessary to screen for hypertension first, and if hypertension is diagnosed, regular treatment must be carried out, which can prevent cerebral hemorrhage or cerebral infarction. Targeted prevention of cerebral hemorrhage is more critical for hypertension, and smoking, which tends to destroy the walls of blood vessels and lead to atherosclerosis. If a patient has a sudden increase in blood pressure, a sudden rupture of a blood vessel may occur. A more specific cause of brain hemorrhage is an aneurysm, which can lead to brain hemorrhage.
