应用持异的放免方法测定表明,肺心病急性加重期患者血浆心钠素水平明显高于正常人,分别为937±89.9pg/ml和410±39.9pg/ml(P<0.01),而且随着心功能不全和水肿的加重,心钠素含量亦逐渐增加;肺心病组血浆心的素水平与PaO_2呈负相关(r=-0.63,P<0.01)。上述结果的产生是机体对于缺氧、肺动脉高压和容量负荷过重情况下的反射性代偿反应,由此推测,心钠素在肺心病的发病和防治上可能具有一定的作用。
Radiographic determination using different methods showed that patients with acute exacerbation of pulmonary heart disease plasma atrial natriuretic peptide levels were significantly higher than normal, respectively, 937 ± 89.9pg / ml and 410 ± 39.9pg / ml (P <0.01), and with Cardiac insufficiency and edema aggravated, and atrial natriuretic peptide increased gradually. Plasma cardiolin levels in pulmonary heart disease group were negatively correlated with PaO 2 (r = -0.63, P <0.01). The above results are the body’s reflex compensatory response to hypoxia, pulmonary hypertension and volume overload, suggesting that atrial natriuretic peptide may play a role in the pathogenesis and prevention of pulmonary heart disease.
