Exercise-induced pulmonary hypertension by stress echocardiography: Prevalence and correlation with right heart hemodynamics.

Objectives: The aim of this study was to determine the prevalence of exercise-induced pulmonary hypertension (EIPH) in consecutive subjects referred for stress echocardiography for chest pain or shortness of breath and correlate echocardiographic diagnosis of EIPH with hemodynamics at right heart catheterization (RHC).

Background: Elevated pulmonary pressure can lead to significant morbidity and mortality. EIPH by ehocardiography has been described in patients with connective tissue disease.
