P1790 Is there any role of exercise Doppler echocardiography to unmask pulmonary hypertension (PH) in patients with systemic sclerosis and baseline echocardiographic measurements for PH in the gray zone?

Background The usefulness of exercise Doppler echocardiography (EDE) is uncertain in identifying patients with pulmonary hypertension (PH). Recently the cut off value for the definition of PH was changed and was set at the level of mean pulmonary arterial pressure (PAP) >20 mmHg, measured by right heart catheterization (RHC). Purpose We examined whether EDE can unmask the presence of PH in patients with systemic sclerosis (SSc) whose...
