Finding better ways to predict survival in patients with pulmonary arterial hypertension.

Who could benefit from this research

What this research studies

This research focuses on improving survival predictions for patients with pulmonary arterial hypertension (PAH) by identifying clinical markers that reflect how well the right ventricle adapts to increased pressures in the pulmonary arteries. The study will analyze data from over 100 patients who have undergone various heart assessments, including right heart catheterization and echocardiograms. By exploring accessible metrics that can serve as indicators of right ventricular adaptation, the research aims to enhance existing clinical risk scores and provide more accurate prognoses for patients with PAH.
