Patients with cerebral infarction should generally have a blood pressure lowering goal of less than 140/90 mm Hg during the recovery period, ideally less than 130/80 mm Hg, and patients with diabetes mellitus combined with hypertension should have strict control of their blood pressure of less than 130/80 mm Hg; during the acute period, it is generally controlled to be less than 180/100 mm Hg, depending on the specific situation. Patients in the recovery phase of the disease have their blood pressure controlled below 140/90 mm Hg, or preferably below 130/80 mm Hg, which is an effective secondary preventive measure and plays a positive role in preventing relapse. Patients with diabetes mellitus combined with hypertension, with both risk factors, have a higher blood pressure control goal and should be below 130/80 mm Hg. Patients in the acute phase, who are prepared for thrombolysis, should control systolic blood pressure <180 mmhg, diastolic blood pressure < 100 mmhg. Blood pressure elevation within 24h after onset of the disease, if systolic blood pressure ≥200 mmhg or diastolic blood pressure ≥110 mmhg, can be given cautious lowering and closely observe blood pressure changes. For those with a history of hypertension and taking antihypertensive drugs, the use of antihypertensive drugs can be resumed 24h after the onset of the disease if the condition is stable.
