About this study
Official title: Analysing the Test-Retest Reliability of Cardiopulmonary Exercise Testing With Echocardiography
CPETecho is progressively employed in diagnostic settings for pathophysiological detection, offering comprehensive assessment of both pulmonary and cardiac functions. This technique evolves from its invasive counterpart, where a diagnostic catheter is employed for hemodynamic monitoring, by substituting the invasive component with non-invasive echocardiography. Nevertheless, data on the test-retest reliability of CPETecho remain sparse, a factor critical in differentiating between measurement effects and actual therapeutic impacts.

Questions about this trial
What is this clinical trial studying?
A study testing CPETecho in people with Dyspnea; Cardiac, run by Ziekenhuis Oost-Limburg at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 15 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Philippe Bertrand, MD, PhD (0032471626094, philippe.bertrand@zol.be), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Correlation coefficient (ICC) (time frame: Up to 2 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2025.
