A chest X-ray is abnormal in the majority of patients with pulmonary hypertension (PH); however, there is no correlation between the severity of PH and the findings on a chest X-ray. Findings of PH on a chest X-ray include pulmonary artery dilatation and right-sided enlargement of the heart. A chest X-ray may suggest that there is no compromise of the left heart if normal and allows for initial assessment of lung disease that can lead to group 2 and group 3 PH, respectively.

Chest X Ray

Findings of PH on a chest X-ray include:[1][2][3]

  • Hilar pulmonary arterial dilation
  • Loss of peripheral blood vessel markings
  • Enlarged right atrium, right ventricle and pulmonary arteries in advanced diseases.[4]

Shown below are chest X-ray images of patients with PH.
