Pulmonary hypertension (PH) is an enigmatic vascular disorder characterized by
pulmonary vascular remodeling and increased pulmonary vascular resistance,
ultimately resulting in pressure overload, dysfunction, and failure of the right
ventricle. Current medications for PH do not reverse or prevent disease
progression, and current diagnostic strategies are suboptimal for detecting
early-stage disease. Thus, there is a substantial need to develop new diagnostics
and therapies that target the molecular origins of PH. Emerging investigations
have defined metabolic aberrations as fundamental and early components of disease
manifestation in both pulmonary vasculature and the right ventricle. As such, the
elucidation of metabolic dysregulation in pulmonary hypertension allows for
greater therapeutic insight into preventing, halting, or even reversing disease
progression. This review will aim to discuss (1) the reprogramming and
dysregulation of metabolic pathways in pulmonary hypertension; (2) the emerging
therapeutic interventions targeting these metabolic pathways; and (3) further
innovation needed to overcome barriers in the treatment of this devastating
disease.
