This study plans to learn more about heart function among individuals with chronic obstructive pulmonary disease (COPD). In particular, the investigators want to understand the different patterns of right ventricular response during rest and moderate- vs high-intensity exercise. By identifying patterns of right ventricular dysfunction, this study will help identify better treatments for patients with COPD in the future.
This study will determine patterns of right ventricular (RV) response to aerobic exercise in patients with chronic obstructive pulmonary disease (COPD) and will design a targeted exercise intervention to improve RV response. We will study 60 patients with COPD. Participants will complete cardiopulmonary exercise testing (CPET) and transthoracic echocardiography (TTE) during rest, moderate- and high-intensity exercise. A subset of participants (n=16) who have been recommended to undergo clinical right heart catheterization will be recruited for the primary study with additional invasive pressur…
