N-Terminal proBNP Levels and Tissue Doppler Echocardiography in Acute Rheumatic Carditis
Figure 5
Receiver-operating characteristic (ROC) curve for plasma NT-proBNP in the diagnosis of acute rheumatic carditis. The area under the curve was 0.978. A cut of value of 265 fmol/mL has a sensitivity of 93% and specificity of 92.9% in detecting acute rheumatic carditis.
