Value of NT - proBNP in differential diagnosis of dyspnea which caused by heart disease or pulmonary disease

Objective: To investigate the value of NT-proBNP in the differential diagnosis of dyspnea caused by heart disease or pulmonary disease. Methods: The NT - proBNP of patients suffered from dyspnea which caused by heart failure or pulmonary disease were measured by immunoenzymometric assay and compared the results. Choose 50 health examples with medical examine as control group, and measured their plasma NT - proBNP level to make comparison analysis. Results: The NT - proBNP level of the patients whose dyspnea were caused by heart disease(2932.80 ± 1808.44) pg/mL were obviously higher than those of patients whose dyspnea were caused by pulmonary disease (282.73 ± 239.05) pg/mL (P < 0.01). Conclusion: NT - proBNP, which has remarkable clinical significance, can be used as the indicator in the differential diagnosis of dyspnea because of its highly sensitivity and specificity.
