The general goal of blood pressure lowering for hypertensive patients is below 140/90 mmHg, but for young people or those with diabetic nephropathy or hypertensive complications, such as cardiac hypertrophy or heart failure, it is recommended to control blood pressure below 130/80 mmHg. However, it is not the case that lower blood pressure is better. For elderly people over 65 years of age, if they cannot tolerate low blood pressure, or due to relatively high systolic blood pressure and low diastolic blood pressure, a severe reduction in blood pressure may lead to diastolic blood pressure below 60 mmHg, which may also lead to insufficient coronary perfusion, which is very bad for the elderly. In elderly patients, if tolerated, the blood pressure can be lowered to below 140/90 mmHg. If the lowering of blood pressure is not tolerated, the blood pressure can be controlled to below 150 mmHg.
