New technical approach can enhance diagnosis of pulmonary hypertension

The management and prognosis of pulmonary hypertension heavily relies on whether the pathology is localized in pulmonary arteries or veins. In particular, at early stages, it is challenging to distinguish pulmonary arterial hypertension (PAH) from the rare subtype of pulmonary veno-occlusive disease (PVOD) because clinical presentations of PAH and PVOD can be similar. A new study in The American Journal of Pathology, published by Elsevier, reports gene expression analysis of lung explant tissue can accurately differentiate PAH from PVOD.
