Interpretation of a new biomarker for the right ventricle introduced to evaluate the severity of pulmonary arterial hypertension

Assessment of right ventricular (RV) performance can be a challenge for clinicians and researchers, especially in the diseased heart. In their study on pulmonary arterial hypertension (PAH) in pediatric patients, Yang et al. sought to identify a quantitative measure to predict disease progression and to assist treatment planning.1 The authors defined a potential biomarker (based on MRI and right heart catheterization data) that appears to correlate with clinical worsening, and outperforms several other metrics studied. During follow-up for a period from 1 to 10 years since diagnosis, an upward trend of the new biomarker was found for patients with clinical worsening (N = 8) compared with a well-defined stable subgroup (N = 9).
