对20例陈旧性心肌梗死患者测定了血浆心钠素并配合二维超声心动图检查.结果:20例血浆心钠素浓度平均为220.21ng/L。局限性陈旧性心肌梗死(n=9)和多部位陈旧性心肌梗死(n=11)的血浆心钠素浓度分别为196.7±33.17ng/L和239.9±66.4ng/L(P>0.05);心功能正常(n=11)和心功能减退者(n=9)的心钠素分别为211.09±58.99ng/L和231.89±56.14ng/L(P>0.05).提示多部位陈旧性心肌梗死及心功能减退者心钠素较局限性陈旧性心肌梗死及心功能正常者略高,但无显著差异.心钠素能否作为心功能减退的早期观察指标有待进一步探讨。
Plasma atrial natriuretic peptide was measured in 20 patients with old myocardial infarction with two-dimensional echocardiography.Results: The average plasma atrial natriuretic peptide concentration in 20 patients was 220.21 ng / L. Plasma atrial natriuretic peptide concentrations were 196.7 ± 33.17 ng / L and 239.9 ± 66.4 ng / L, respectively (P> 0.05) in patients with localized AMI (n = 9) and multiple sites of AMI (n = 11) The atrial natriuretic peptide scores were 211.09 ± 58.99ng / L and 231.89 ± 56.14ng / L, respectively, with normal cardiac function (n = 11) and hypothyroidism (n = 9) And heart failure patients with atrial natriuretic sodium than the limitations of old myocardial infarction and normal heart rate was slightly higher, but no significant difference.As atrial natriuretic peptide early observation index to be further explored.
