Pulmonary Vascular Remodeling in Pulmonary Hypertension Due to Chronic Heart Failure

Abstract

Medial hypertrophy of muscular pulmonary arteries is more common and severe than expected in patients with CHF, even in patients without at-risk PHT. This structural change could explain why PHT, even in range of values not excluding HT, is a risk factor for right ventricular failure after HT and influences post-HT haemodynamic behaviour.
