Blood pressure plays a very important role in the development of chronic renal failure patients. For patients with chronic renal failure combined with hypertension, the target value of blood pressure control is usually around 130/80mmHg. The blood pressure of chronic renal failure patients should not be lowered too low, too low is easy to reduce renal blood flow, resulting in insufficient blood supply to the kidneys, which may accelerate the further deterioration of renal function. Meanwhile, in the process of lowering blood pressure, it should also maintain the stability of blood pressure and minimize the fluctuation of blood pressure, so as not to cause damage to the function of other organs. Therefore blood pressure is often controlled at around 130/80mmHg. It is recommended that patients with chronic renal failure closely monitor their blood pressure, which can be measured in several times, such as in the morning, in the middle of the day, in the evening and at bedtime, in order to avoid further damage to the kidneys. If patients with chronic renal failure have abnormal blood pressure, it is recommended that they go to the hospital immediately and follow the doctor’s instructions to rationally adjust the blood pressure lowering program.
