Why the study?
Is the thickening of the media of pulmonary muscular arteries in pulmonary hypertension the result of vasoconstriction, medial hypertrophy, or both?

In patients with congenital heart disease and pulmonary hypertension, thickening of pulmonary muscular arteries is primarily driven by medial hypertrophy, though vasoconstriction also plays a significant role in certain cases.
No takes yet. Share an insight, caveat, or question.
Supports medial hypertrophy predominance in congenital PH; leaves open vasoconstriction-targeted therapies for prospective validation.
