The value of plasma N-terminal pro-brain natriuretic peptide levels in diagnosing and differentiating in patients presenting with acute dyspnea / 中国实用内科杂志

ABSTRACT

Objective To investigate the clinical value of the plasma N-terminal pro-brain natriuretic peptide levels in patients with acute cardiac dyspnea or noncardiac dyspnea.Methods 93 patients with acute dyspnea were divided into two groupscardiac dyspnea group(61 cases)and noncardiac dyspnea group(32 cases).In cardiac dyspnea group,according to the results of echocardiography,the cases were divided into three groupspure diastolic heart failure(25 cases),pure systolic heart failure(21 cases)as well as diastolic and systolic heart failure(15 cases).At the same time,heart function was classified according to NYHA.The plasma NT-proBNP level was measured by ELISA.The data was analyzed by SPSS12.0.Results The plasma NT-proBNP level of the cases with cardiac dyspnea and noncardiac dyspnea was(3.591 ?2.943)ng/L and(0.429 ?0.119)ng/L respectively.There was a significant difference between cardiac dyspnea cases and noncardiac dyspnea cases(P
