Abstract

Objective:

Pulmonary artery hypertension is difficult to diagnose because of its nonspecific symptoms. Although echocardiography and more accurately catheterization can recognize the pulmonary artery pressure, chest X ray is widely used because of its availability. The objective of this study was to evaluate the accuracy of Chest radiography parameters for estimation of pulmonary artery pressure.



Methods & Materials:

This cross-sectional study included 81 subjects with a definite diagnosis of pulmonary artery hypertension. Mean pulmonary artery pressure (mPAP) was determined by Catheterization. Hilar widening, projection of the right side of the heart border (PRHB), hilar widening+PRHB and the ratio of these parameters to the thoracic diameter were compared to mPAP to evaluate correlations.



Results:

Average mPAP was 74.7±21 (ranging from 28 to 120 mmHg). Spearman's test revealed significant correlation between mPAP and hilar widening (r=0.489, P=0.000), hilar/thoracic ratio (r=0.482, P=0.001<) , hilar widening + PRHB (r= 0.517, P=0.001<) and hilar+PRHB/thoracic ratio(r:463, P=0.001<).



Conclusion:

Hilar widening and hilar/thoracic ratio on the chest radiography is a proper parameter for estimation of the pulmonary artery pressure.
