The value of using NT-proBNP detection to identify cardiogenic dyspnea and pulmonary dyspnea

Objective To study the clinical value of plasma N-terminal pro-B-type natriuretic peptide detection in patients with dyspnea.Methods There were 98 patients with dyspnea,we made the initial diagnosis according to the history,the conventional laboratory examination method,blood-gas analysis,electrocardiogram,chest X-ray and heart color dopplar ultrasound inspection.At the same time we detected the level of NT-pro BNP in plasma by using rapidly chemiluminescence detection,then compared plasma NT-proBNP level.Results Among 98 patients,there were 42 cases who caused by heart failure(cardiogenic),56 cases caused by respiratory disorders(respiratory).Finally we confirmed cardiogenicdyspnea 44 and respiratory dyspnea 54.The median NT-pro-BNP level in patientswith cardiogenic dyspnea was(2993±183) pg/mL as compared to(2993±183)pg/mL in patients with respiratory.dyspnea.Conclusion Rapid NT-proBNP detection has significance in differential diagnosis of cardiac and pulmonary dyspnea.It has high sensitivity,high specificity and can be used as a cardiac dyspnea independent testing factor.
