本文通过对５２例心功能不全患者血浆心钠素水平的观察，发现心功能不全患者血浆心钠素（１２１２．６±１８６．９ｐｇ／ｍｌ）明显高于对照组（４５４．４±７２．５ｐｇ／ｍｌ，Ｐ＜０．０１）；由于病情轻重不同，病程长短不同，心钠素水平也各不相同；经治疗病情改善后，心钠素水平也趋于下降，接近正常对照值（从９４４．５±１８６．４ｐｇ／ｍｌ下降到３９８．２±７４．８ｐｇ／ｍｌ，Ｐ＜０．０１）．结果表明，心功能不全时血浆心纳素浓度增加有利于心功能的纠正，是机体重要的保护性代偿机制．
In this paper, 52 cases of cardiac dysfunction in patients with plasma atrial natriuretic peptide levels observed in patients with cardiac dysfunction, plasma atrial natriuretic peptide (1212.6 ± 186.9pg / ml) was significantly higher than the control group (454.4 ± 72.5pg / Ml, P <0.01); atrial natriuretic peptide levels also varied due to different disease severity and duration of disease; atrial natriuretic peptide also tended to decrease after treatment, approaching the normal control value (from 944 .5 ± 186.4 pg / ml to 398.2 ± 74.8 pg / ml, P <0.01). The results show that cardiac insufficiency increases plasma concentrations of plasma concentrations of cardiac function is conducive to correct, the body is an important protective compensation mechanism.
