There is a correlation between blood pressure and cardiovascular and cerebrovascular complications, and there are no prevalent values for blood pressure control targets, and the ranges are usually: 1. For patients under 60 years of age, it is recommended to control systolic blood pressure ≤ 140 mmHg and diastolic blood pressure ≤ 90 mmHg; 2. For patients with combined renal disease or diabetes, it is recommended to control systolic blood pressure ≤ 130 mmHg and diastolic blood pressure ≤ 80 mmHg; 3. For patients over 80 years of age, it is recommended to control systolic blood pressure ≤ 150 mmHg; 4. Individualized antihypertensive programs are developed for patients to control blood pressure and reduce complications and target organ damage.
