The control of blood pressure in patients with cerebral infarction is generally within the normal range, such as systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg. If there is severe stenosis of intracranial blood vessels, the blood pressure should be higher to prevent low perfusion of the brain caused by lower blood pressure, which aggravates the condition of cerebral infarction. If the patient is elderly and often has atherosclerosis, the blood pressure control should be relatively high. For patients with cerebral infarction, if the blood pressure rises within 24 hours of onset, it is generally not recommended to give timely antihypertensive treatment, but mainly to give antihypertensive treatment as well as sedation treatment, which may be mainly due to stress, anxiety, or Stress. The control of blood pressure in patients within 24 hours mainly follows the following principles: when the systolic blood pressure is persistently elevated, >200 mmHg, and diastolic blood pressure ≥110 mmHg, patients with combined heart disease should be given cautious antihypertensive treatment, while closely monitoring the changes of blood pressure dynamically. When patients need thrombolytic therapy, blood pressure should be controlled to systolic blood pressure <180 mmHg and diastolic blood pressure <110 mmHg. 24 hours after the onset of the disease, patients should generally be given conventional blood pressure lowering therapy.
