The annual incidence of cerebral hemorrhage is 250 per 100,000, while patients with cerebral hemorrhage who have hypertension account for about 90% or more of the patients and are the main cerebrovascular disease causing death. The most common site of hemorrhage is the basal ganglia region of the cerebral hemispheres, accounting for about 50% to 60% of cerebral hemorrhages. The increase in intracranial pressure caused by hematoma and the brain herniation that occurs when brain tissue is displaced by pressure are the direct causes of patient death. The death rate of acute cerebral hemorrhage is about 30-40%. Brain hemorrhage is a major killer of human beings, how should we keep away from it? The direct causes of cerebral hemorrhage are reduced elasticity of cerebrovascular artery walls and poorly controlled hypertension; risk factors for cerebral hemorrhage include diabetes, hyperlipidemia, smoking, alcohol abuse and fatigue. Evidence-based medicine shows that the risk of stroke in patients with satisfactory blood pressure control is at the same level as in patients without a history of hypertension. Therefore, long-term stable control of hypertension and effective removal of high-risk factors are effective measures to keep away from hypertensive cerebral hemorrhage. Only by delaying or preventing cerebral atherosclerosis can we maintain a strong resistance of the cerebrovascular arterial wall to counteract the impact damage effect of transient hypertension on cerebral vessels, thus reducing the risk of cerebral hemorrhage. First, effective long-term control of hypertension and prevention of sudden and dramatic increases in blood pressure is the key to preventing cerebral artery rupture. Among the patients with cerebral hemorrhage admitted to our neurosurgery department, 80% of them have a history of hypertension, but they do not take medication regularly or reduce or stop medication without authorization, and a large proportion of them rely on “prescriptions” to lower their blood pressure. Most of the patients with cerebral hemorrhage we see do not monitor their blood pressure scientifically and regularly. In this regard, we make an analogy: only five out of ten of our patients know that they have high blood pressure, only three out of five know that they are taking medication, and only one out of three is taking the medication correctly, so the remaining nine people are suffering from brain hemorrhage. This is a bit alarming, but if high blood pressure is not effectively controlled, patients are at a much higher risk of developing a brain hemorrhage than the normal population. We generally require that patients should have blood pressure below 140/90mmHg, and patients with coronary heart disease and diabetes should have blood pressure below 130/80mmHg. During the period when blood pressure is not up to standard, blood pressure should be measured once a day so that medication can be adjusted until it is up to standard; after it is up to standard, blood pressure should be measured at least once a month to ensure that it is always controlled within the standard. The basic methods of effective control of hypertension are: long-term adherence to standardized drug therapy (oral long-acting slow-release preparations are recommended), try to smoothly lower blood pressure 24 hours a day (do not stop the drug and arbitrarily increase the dose); low salt and more vegetables; quit smoking and limit alcohol; lose weight; appropriate exercise and avoid emotional excitement. Second, control risk factors. Control blood lipids and blood cholesterol levels: regardless of hypercholesterolemia, hypertriglyceridemia, high LDLemia and low HDLemia, all four are abnormal lipidemia and are also independent risk factors for the occurrence of atherosclerosis. The basic measure to correct abnormal lipidemia is to control 30 grams of edible fats, 200 grams of meat, poultry, fish and eggs, and 400 grams of pasta and other high-energy foods in the daily diet; if the diet cannot be controlled or is unsatisfactory, “statins and betas” can be used alone or in combination according to the characteristics of abnormal lipidemia. “Lipid-lowering drugs, standardized treatment, frequent testing, long-term maintenance of lipids in the normal range. Reasonable control of blood sugar, the incidence of atherosclerosis in diabetic patients is 2 to 4 times higher than in non-diabetic patients, and the disease is more serious, the age of onset is earlier, and atherosclerotic disease often becomes the direct cause of death in diabetic patients. Diabetic patients are mostly associated with risk factors such as abnormal lipidemia, insulin resistance, and coagulation disorders. If the dietary control is not satisfactory, according to the different pathological states of diabetic patients, they can use or combine “insulin, insulin sensitizers, insulin secretagogues and biguanides” to carry out standardized treatment, and should be tested frequently to keep blood sugar in the normal range for a long time. In addition, season and climate are also related to cerebral hemorrhage. In winter, the prevalence of cerebral hemorrhage is high, and in summer, when the outside temperature is high, cerebral hemorrhage can also be triggered by the low temperature of indoor air conditioning. Therefore, proper warmth and avoiding sudden cold and heat are also effective measures to prevent cerebral hemorrhage.
