Brain infarction and hypertension are directly related, and hypertension is the most important independent risk factor for brain infarction. Patients with hypertension have a higher chance of cerebral infarction, and if long-term hypertension is not well controlled, it may cause continuous atherosclerosis of cerebral blood vessels, which may lead to local plaque formation or lumen narrowing of cerebral blood vessels, easily causing ischemia and necrosis of brain tissue. Therefore, if patients suffer from long-term hypertension, they should insist on taking antihypertensive drugs such as amlodipine benzoate tablets and enalapril maleate tablets to control blood pressure in order to prevent the occurrence of cerebral infarction. If a patient has hypertension in combination with cerebral infarction, he or she should also actively choose reasonable antihypertensive drugs to control blood pressure, and pay attention to a light diet and control sodium intake. In addition, weight control and physical exercise can effectively prevent the occurrence of hypertension and cerebral infarction.
