The Clinical Value of BNP Detection in Diagnosis of the Cause of Emergency Dyspnea and Assessment of the Extent of Cardiac Involvement

Objective To discuss the clinical value of BNP detection in the diagnosis of the causes of emergency dyspnea and assessment of cardiac function. Methods A total of 168 patients with emergency dyspnea were divided into the cardiac dyspnea group( cardiogenic group) and the pulmonary dyspnea group( pulmonary group),and then BNP detection and echocardiography were performed in the two groups,and were contrasted between the two groups. Results BNP in the cardiogenic group was significantly higher than the pulmonary group [( 813. 6 ± 201. 4) ng / L vs( 234. 5 ± 189. 8) ng / L,P 0. 01],and LVEF was significantly lower than the pulmonary group[( 44. 6 ± 9. 2) % vs( 62. 3 ±8. 8) %,P 0. 01 ]; BNP in cardiac dyspnea patients with NYHA Ⅱ was significantly lower than patients with NYHA Ⅲ and patients with NYHA Ⅳ[( 398. 7 ± 215. 8) ng / L vs( 846. 6 ± 224. 3) ng / L vs( 1086. 9 ± 231. 4) ng/L,P 0. 01],and BNP of patients with NYHA Ⅲ was significantly lower than NYHA Ⅳ( P 0. 01). Conclusion BNP can be used for differential diagnosis of the causes of disease and the assessment of the degree of cardiac involvement in emergency dyspnea patients.
