高血压是慢性肾功能衰竭时常见的并发症。在我院收治的病例中占70.8%,进行血透治疗者占90%。发生高血压后不仅促进心血管病变的发展,还加速肾功能衰竭,必须积极治疗。高血压的发生大部分是因容量负荷过多所致,占85～90%。此外肾素—血管紧张素(R-A)系统活性增强,激肽—前列腺素系统的活性相对不足以及交感神经系统功能异常等亦有一定作用。因此,治疗高血压首先是去除过多的容量负荷,应限制钠的摄入量使其与肾脏的排钠能 Hypertension is a common complication of chronic renal failure. In our hospital admitted cases accounted for 70.8%, hemodialysis treatment accounted for 90%. Hypertension not only promote the development of cardiovascular disease, but also accelerate renal failure, we must actively treat. Hypertension occurs mostly due to excessive capacity load, accounting for 85 to 90%. In addition, renin - angiotensin (R-A) system activity increased, kinin - prostaglandin system activity is relatively inadequate and sympathetic dysfunction also play a role. Therefore, the treatment of hypertension first is to remove excessive volume load, sodium intake should be limited to make it with the renal side effects of sodium
