Cardiopulmonary Rehabilitation in COVID-19 Longhaulers
Purpose
This study will test the efficacy of treadmill exercise combined with supplemental oxygen during exercise and recovery for the treatment of persistent post-acute COVID-19 symptoms. Participants will be pseudo-randomized (stratified by age) to one of four conditions for 8 treatment sessions: 1) treadmill exercise plus supplemental oxygen, 2) treadmill exercise plus air, 3) supplemental oxygen only, 4) air only. All participants will then cross-over and receive 16 additional sessions of treadmill exercise plus supplemental oxygen.

Inclusion Criteria
- Between the ages of 18-60 - Contracted COVID-19 between February - July 2020 - Has been clinician-diagnosed with COVID-19 based on PCR/antigen testing, antibody testing, or clinical symptoms - Is currently experiencing one or more of the following symptoms, which began only after contracting COVID-19 : dyspnea, cough, chest pain, tachycardia or other arrhythmias, hypertension, hypotension, blood pressure lability, oxygen desaturation, exercise/activity intolerance, fatigue, or dizziness. - Has been cleared by a physician for exercise and supplemental oxygen. - Has the capacity to provide written, informed consent - Able to complete questionnaires in English
Exclusion Criteria
- History of any of the following per the American College of Sports Medicine exercise testing guidelines (American College of Sports Medicine et al., 2018) to be determined during a screening consultation: 1. Acute myocardial infarction within the past two days 2. Ongoing unstable angina 3. Uncontrolled cardiac arrhythmias 4. Active endocarditis 5. Symptomatic severe aortic stenosis 6. Decompensated heart failure 7. Active pulmonary embolism, pulmonary infarction, or deep venous thrombosis 8. Active myocarditis or pericarditis 9. Acute aortic dissection 10. Physical disability that precludes safe and adequate testing - Participants who demonstrate orthostatic intolerance or oxygen desaturation (<90%) during the exercise tolerance test will no longer be eligible for the study because it is not safe for them to exercise on a treadmill.

- Crossover Assignment
- Intervention Model Description
- This study entails 24 treatment sessions. The first 8 sessions involve four experimental conditions: 1) exercise + oxygen (treatment), exercise + air (active control), oxygen only (active control), air only (placebo). Pre-treatment testing will then be repeated, after which all participants will crossover to 16 sessions of exercise + oxygen.

- Masking Description
- All participants will be blind to whether they receive supplemental oxygen or air during the first 8 sessions.
Arm Groups
Arm | Description | Assigned Intervention |
---|---|---|
Experimental Treadmill Exercise with Supplemental Oxygen |
Participants will receive 24 sessions (2 x week for 12 weeks) of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes. |
|
Sham Comparator Treadmill Exercise with Air |
Participants will receive 8 sessions (2 x week for 4 weeks) of treadmill exercise combined with air delivered via nasal cannula during exercise and 5-minutes of recovery. They will then cross-over to 16 sessions of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes. |
|
Sham Comparator Supplemental Oxygen Only |
Participants will receive 8 treatment sessions (2 x week for 4 weeks) of 6 liters per minute of continuous oxygen via nasal cannula for 30 minutes at rest. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three minutes. They will then cross-over to 16 sessions of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three to five minutes. |
|
Placebo Comparator No Intervention |
Participants will receive 8 treatment sessions (2 x week for 4 weeks) of air via nasal cannula for 30 minutes at rest. Heart rate, rhythm, and oxygen saturation will be continuously monitored, and blood pressure readings will be obtained every three minutes. They will then cross-over to 16 sessions of treadmill exercise combined with 6 liters per minute of supplemental oxygen via nasal cannula during exercise and 5-minutes of recovery. The first treadmill session will last 25% longer than the exercise tolerance test, but at a lower intensity, such that 80-100% of peak exercise intensity calculated from the exercise tolerance test MET is achieved within three sessions, after which time and intensity will be increased by no more than 0.5 METS, as tolerated based on symptoms and vitals.

Detailed Description
This study will test the efficacy of a COVID-19 specific cardiopulmonary rehabilitation protocol for treatment of persistent post-acute COVID symptoms and to study the impact of cardiopulmonary improvement on cognition, mental health, and function. Participants (N=36) with persistent post-acute COVID symptoms will undergo pre-treatment neurocognitive, orthostatic tolerance, and exercise tolerance tests before being pseudo-randomized (stratified by age and sex) to one of four conditions (all of which occur twice a week): 1) 8 sessions of treadmill exercise plus supplemental oxygen, 2) 8 sessions of treadmill exercise plus air, 3) 8 sessions of supplemental oxygen only, and 4) 8 sessions of air only. The pre-treatment testing will be repeated, after which all participants will receive 16 additional sessions of treadmill exercise plus supplemental oxygen, followed by post-treatment testing. All participants will complete baseline measures of physical and mental health, physical function, emotional wellbeing, and coping. A brief symptom measure will be collected daily and physical function, mental health, and emotional wellbeing will be assessed weekly.
