Right Ventricular Response to Exercise Among Patients With Chronic Obstructive Pulmonary Disease
(ReV UP COPD)
What this study is about
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.
View original scientific description
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- COPD (determined by ratio of forced expiratory volume in 1 second to forced vital capacity \[FEV1/FVC\] \<0.7)
- Age \>= 40 years
Exclusion criteria
- Exacerbation of COPD in the 3 months prior to enrollment
- Change in COPD therapy in the 3 weeks prior to enrollment
- Requirement of \>6 LPM supplemental oxygen at rest
- Requirement of \>10 LPM supplemental oxygen with exertion
- Active/uncontrolled cardiovascular disease (e.g. hypertension with blood pressure \>150/100 despite antihypertensives; coronary artery disease with angina; left ventricular ejection fraction ≤40%; uncontrolled arrhythmia; pulmonic, mitral or aortic valvular abnormality greater than mild in severity; tricuspid regurgitation greater than moderate in severity)
- Volume overload (jugular vascular distension or greater than trace peripheral edema)
- World Health Organization Functional Class IV
- Known pulmonary hypertension with mean pulmonary artery pressure \>45 mmHg
- Untreated severe obstructive sleep apnea and/or obesity hypoventilation syndrome
- Active malignancy (other than skin)
- Medical conditions that limit exercise on an upright stationary bicycle (e.g. severe osteoarthritis, imbalance/gait instability, etc.)
- Body mass index \<18 or \>35
- Hematocrit \<25% or \>55%
- For subset undergoing right heart catheterization, chronic anticoagulation that is unable to be held for the study visit
- For subset undergoing right heart catheterization or exercise training, forced expiratory volume in 1 second of \<20%
- For exercise training, already engaged in routine exercise training (\>30 minutes at \>3 METs 3 times/week or more)
- For exercise training, inability to complete initial in-person exercise training sessions for approximately 35 minutes 3x/week for 3 weeks (followed by exercise training sessions with an option for hybrid remote/in-person participation)
- For exercise training with an option for hybrid remote exercise training, any medical conditions which threaten the safety of remote exercise training (e.g. imbalance/gait instability, etc.).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
