A review of chest X-ray in pulmonary hypertension: correlation of right descending pulmonary artery diameter with mean pulmonary artery pressure

Background: Pulmonary hypertension is a condition which there an increase in mean pulmonary artery pressure measured at ≥25 mmHg. The gold standard diagnosing this right heart catheterization. Enlargement of descending on chest radiographs sign hypertension. However, the value radiographic measurements reported was diverse. study analyzes correlation between (RDPA) diameter and means catheterization to understand whether RDPA X-ray could be predictor determining severity hypertension.Methods: Thirty-five subjects were reviewed compare from posteroanterior projection mPAP them analyzed using Pearson's test. cut-off point defined ROC curve.Result: revealed high positive (p<0.001; r=0.824). 21.8 mm (sensitivity 81% specificity 85.7%; AUC =0.9)Conclusion: measurement x-ray positively correlates with pressure. Therefore, can predict
