Blood pressure and cerebral infarction are related, because hypertension is an independent high-risk factor for cerebral infarction, for patients with high blood pressure because of long-term vascular pressure is relatively large, so there will be varying degrees of vascular endothelial cell changes, vascular endothelial cell hyperplasia, and atherosclerosis will occur. When atherosclerosis occurs in coronary arteries or cerebral arteries, it will aggravate the risk of cerebral infarction, so hypertension has become an independent high-risk factor for cerebral infarction, and patients with cerebral infarction must control their blood pressure to a normal level. In addition, if the blood pressure is too high, the patient will also have hypertensive encephalopathy, which will aggravate the risk of cerebral infarction, so the blood pressure and cerebral infarction are directly related, and the blood pressure must be controlled in the standard and normal range, in order to reduce the risk of cerebrovascular diseases, such as cerebral infarction.
