高血压及心血管病是老年人常见病之一。其发病率明显高于青壮年。目前认为影响血压的因素最终与动脉收缩和/或血容量的改变有关。RAAS对上述两种因素起着极其重要的作用。因此探讨老年人RAAS的变化,对研讨老年人的高血压及心血管病的发病机制及防治工作有一定的临床意义。我们对30例健康老年人进行了血浆肾素活性(PRA)一血管紧张素Ⅱ(AngⅡ)—醛固酮(Ald)测定。现将其结果分析讨论如下。
Hypertension and cardiovascular disease is one of the common diseases in the elderly. The incidence was significantly higher than young adults. It is currently believed that the factors that affect blood pressure are ultimately related to arterial contractions and / or changes in blood volume. RAAS plays an extremely important role on these two factors. Therefore, to explore the changes of RAAS in the elderly has some clinical significance for studying the pathogenesis and prevention of hypertension and cardiovascular diseases in the elderly. We measured plasma renin activity (PRA) and angiotensin II (Ald) - aldosterone (Ald) in 30 healthy elders. The results of the analysis are discussed below.
