Khassafi et al. identify molecular subgroups of right ventricular (RV) dysfunction using transcriptomic analysis of RV samples from individuals with compensated RV hypertrophy or decompensated RV failure and two rat models of RV dysfunction. Several extracellular matrix genes found to be deregulated in decompensated RV subgroups were validated at the protein level in two independent cohorts of individuals with pulmonary arterial hypertension, revealing their predictive biomarker potential in maladaptive RV development.
