Sensitivity, Specificity, and Diagnostic Accuracy of Noninvasive Assessment of Pulmonary Hypertension by Doppler Echocardiography at Various Cut‐Off Levels

Cut‐off sPAP, mm Hg	Sensitivity, %	Specificity, %	PPV, %	NPV, %	ACC, %
≥26	98.5	28.7	78.1	88.3	79.0
≥31	94.6	58.0	85.3	80.6	84.4
≥36	87.0	79.1	91.5	70.2	84.8
≥41	73.1	91.4	95.6	56.8	78.2
≥46	59.5	97.0	98.1	48.2	70.0

ACC indicates accuracy; NPV, negative predictive value; PPV, positive predictive value; sPAP, systolic pulmonary arterial pressure.
