About this study
Official title: Using the Stress Ventricular Function Assessment to Evaluate the Long-term Prognosis and Treatment Outcome in Patients With Pulmonary Hypertension
This study investigated clinical parameters, laboratory data, imaging studies to evaluate patients with suspected pulmonary hypertension.
Read the detailed description
Left and right ventricular ejection fraction (LV/RV EF) at rest and immediately after exercise treadmill test (ETT) were measured by nuclear medicine study in consecutively symptomatic patients with suspected pulmonary hypertension, along with other clinical variables were correlated with right heart catheterization parameters.
