慢性肾脏病和高血压是两个密切相关的公共健康问题。肾脏是调节血压的重要器官，肾脏病变可以导致血压升高，高血压又进一步加快肾脏病变进展，形成恶性循环，影响患者预后。容量扩张是慢性肾脏病患者高血压发生的重要机制。因此，应注重慢性肾脏病高血压患者的容量管理。“,”Chronic kidney disease (CKD) and hypertension are two closely interlinked public health problems. Kidney is an important organ for regulating blood pressure. Renal lesions may lead to increased blood pressure, and hypertension further accelerates the progression of renal disease, thereby forming a vicious circle which affects the prognosis of patients. Volume overload is an important mechanism in the development of hypertension in patients with CKD. Therefore, more emphasis should be put on volume management of CKD patients with hypertension.
