Test-Retest Reliability of Cardiopulmonary Exercise Testing With Echocardiography

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.

Inclusion Criteria:

• Capable of performing a maximal exercise test.
• Provide signed and dated informed consent.
