Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals diagnosed with COPD and evidence of pulmonary artery enlargement.
✕Probably not a fit
Patients with severe cardiovascular disease or those requiring high levels of supplemental oxygen may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to investigate heart function in individuals with chronic obstructive pulmonary disease (COPD), focusing on how the right ventricle responds to pulmonary hypertension during both rest and exercise. By utilizing right heart catheterization and imaging techniques, the researchers will identify patterns of right ventricular dysfunction. The findings could lead to improved treatment strategies for COPD patients by enhancing our understanding of their cardiovascular health.
Why it matters
Potential benefit: If successful, this study could lead to better treatment options for patients with COPD and associated right ventricular dysfunction.
How similar studies have gone: While there is ongoing research in this area, this specific approach to understanding right ventricular dysfunction in COPD through exercise and imaging is relatively novel.
