Abstract:
:We investigated the accuracy of computed tomographic measurements of main pulmonary artery diameter (MPAD) and of MPAD/ascending aorta diameter (AAD) in predicting moderate or severe pulmonary hypertension in 190 patients with acute pulmonary embolism. A pulmonary artery systolic pressure of > or = 50 mm Hg measured by Doppler echocardiography was considered moderate or severe pulmonary hypertension. A MPAD of > 28.6 mm and a MPAD/AAD ratio of > or = 1.00 measured by computed tomography were considered abnormal. A MPAD of > 28.6 mm had a 75% sensitivity and specificity, a 52% positive predictive value, a 89% negative predictive value, a 3.0 likelihood ratio for a positive test, and a 0.33 likelihood ratio for a negative test in predicting moderate or severe pulmonary hypertension. A MPAD/AAD ratio of > or = 1.00 had a 59% sensitivity, a 82% specificity, a 55% positive predictive value, a 84% negative predictive value, a 3.3 likelihood ratio for a positive test, and a 0.50 likelihood ratio for a negative test.
