PH was diagnosed if mean pulmonary artery pressure was >25 mmHg, and mean pulmonary wedge pressure <15 mmHg. Prior to RHC, postero-anterior and lateral digital CXR were obtained, and were examined independently by 5 raters, who were blinded to clinical and hemodynamic data. The radiologic diagnosis of PH was made if a prominent main pulmonary artery was associated with at least one of the following: enlargement of the right ventricle, right descending pulmonary artery >16 mm in diameter, pruning of peripheral pulmonary vessels.Seventy-nine patients (75%) had PH confirmed at RHC. The weighted sensitivity of CXR was 97% (95% confidence interval [CI], 95 to 98%), and the weighted specificity 96% (95% CI, 91 to 99%). The positive likelihood ratio was 25 (95% CI, 11 to 60), and the negative likelihood ratio 0.03 (95% CI, 0.02 to 0.06).CXR is accurate in predicting or excluding PH. It can be used in clinical practice to select patients with clinically suspected PH for hemodynamic ascertainment. ER -
