Guidelines for blood pressure management in acute cerebral infarction clearly state that within 72 h after the onset of acute cerebral infarction, as long as the systolic blood pressure does not exceed 220 mmHg, no antihypertensive treatment can be given. If the systolic blood pressure exceeds 220 mmHg, drugs such as uradil and sodium nitroprusside can be given to control blood pressure, and it is sufficient to control the systolic blood pressure below 220 mmHg, and the blood pressure should not be lowered too low. At the same time, short-acting oral antihypertensive drugs such as nitrendipine should be avoided. However, if the patient is prepared for intravenous thrombolysis or endovascular treatment, the systolic blood pressure should be lowered to 180 mm Hg. After 72 h of onset, if the patient’s systolic blood pressure still exceeds 140 mm Hg, antihypertensive therapy can be initiated, and the reduction of blood pressure should be controlled at 15% per week. Long-acting antihypertensive drugs are preferred, such as amlodipine benzoate, benazepril, bisoprolol, etc.
