Contrast Echocardiography During Exercise to Assess Pulmonary Blood Volume
Assessment of Pulmonary Blood Volume Using Contrast Echocardiography During Exercise
Source: ClinicalTrials.gov · Last updated 20 Aug 2026
Brief summary (registry, in English)
The purpose of this study is to evaluate whether pulmonary blood volume (PBV) derived from contrast echocardiography can serve as a non-invasive surrogate for invasive pulmonary artery wedge pressure (PAWP) during exercise. Also, to compare changes in PBV with exercise in patients with and without heart failure and pulmonary vascular disease.

Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.
Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Prior adverse reaction to echo contrast administration
Other
- Patient inability or unwillingness to undergo echocardiography including a contrast method, or if echocardiography would, in the opinion of the investigator, somehow compromise the quality of data acquisition for the clinical case.
Who the study is looking for
- Patients referred to the cardiac catheterization laboratory for invasive exercise right heart catheterization for evaluating exertional dyspnea. Investigators will include patients with normal or low EF, and across the spectrum of pulmonary hypertension severity.
