目的:探讨心钠素在急性呼吸困难中的诊断和鉴别诊断意义。方法:急性呼吸困难患者110例,测定血浆心钠素水平,以ANP=0.29pg/L为阳性界定值对其诊断心衰的价值进行评价。结果:心衰患者ANP明显高于非心衰患者,以ANP=0.29pg/L为阳性界定值,ANP诊断心源性呼吸困难的敏感性为95.00%,特异性为88.64%,阳性预测值为86.36%,阴性预测值为95.12%。结论:ANP对于诊断和鉴别诊断急性呼吸困难,具有重要意义。
Objective: To investigate the significance of the diagnosis and differential diagnosis of atrial natriuretic peptide in acute dyspnea. Methods: A total of 110 patients with acute dyspnea were enrolled in this study. Plasma atrial natriuretic peptide levels were measured. The diagnostic value of ANP was 0.29pg / L. Results: The ANP in patients with heart failure was significantly higher than that in non-patients with heart failure. ANP was 0.29pg / L. The sensitivity and specificity of ANP in diagnosing cardiogenic dyspnea were 95.00% and 88.64% respectively. The positive predictive value was 86.36%, negative predictive value was 95.12%. Conclusion: ANP is of great significance in the diagnosis and differential diagnosis of acute dyspnea.
