Covid19, Coronavirus Infection, SARS-CoV Infection
Conditions
Brief summary
While many people with COVID-19 suffer from respiratory disease, there is growing evidence that the virus also affects other organs. The purpose of this study is to better understand the effects of COVID-19 on the lungs and other organs. The study investigators have developed new techniques in Magnetic Resonance Imaging (MRI) to scan the lungs, heart, brain and liver. The study investigators hope to learn more about how the virus causes inflammation in these organs and how this inflammation changes over time as people recover from COVID-19 illness. The study aims to enroll 228 people in Alberta. Participants will undergo one or more MRI scans and have blood testing at one or more time points to assess for inflammation, kidney function, liver function and possible heart injury. Participants will also undergo testing to assess sense of smell, cognition (thinking and memory), spirometry (breathing test for lung function) and and exercise tolerance (walk test). The study investigators hope this study will help us learn more about the long-term risks of COVID-19 disease.
Detailed description
Participants with newly or recently diagnosed COVID-19 infection (inpatients and outpatients) will undergo multi-organ MRI (heart, brain, lungs, liver), blood work, and functional testing at one or more time points. Functional testing will include olfaction testing, cognitive testing, spiromety, and a walk test.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Native myocardial T1 relaxation time | 12 weeks post COVID-19 diagnosis | Myocardial T1 is a surrogate marker of myocardial edema and the most sensitive MRI measure of acute myocarditis. We will show that myocardial T1 at baseline is significantly higher than myocardial T1 at 12 weeks follow-up. At 12 weeks, we will also compare native myocardial T1 in patients with baseline elevated troponin to those with baseline normal troponin as well as healthy controls |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Compare 12-week cognitive testing to the corresponding findings on MRI of brain, heart and lung at baseline | 12 weeks post COVID-19 diagnosis | Compare 12-week cognitive testing (NIH toolbox score) to the corresponding findings on MRI of brain, heart and lung at baseline |
| Compare 12-week spirometry to the corresponding findings on MRI of brain, heart and lung at baseline | 12 weeks post COVID-19 diagnosis | Compare 12-week spirometry (FEV1, FVC and FEV1:FVC) to the corresponding findings on MRI of brain, heart and lung at baseline |
| FLAIR imaging | 12 weeks post COVID-19 diagnosis | Similar within group and between group comparisons of MRI derived lung water content, liver water content, and the presence of brain inflammation on FLAIR imaging |
| Compare 12-week cognitive testing in patients with normal smell and/or normal appearing brainstem on MRI to patients with no or impaired smell and/or injury to brainstem on MRI | 12 weeks post COVID-19 diagnosis | Compare 12-week cognitive testing in patients with normal smell and/or normal appearing brainstem on MRI to patients with no or impaired smell and/or injury to brainstem on MRI |
| Compare MRI measures of organ dysfunction at 12-24 weeks in survivors according to severity of prior COVID-19 illness: (i) hospitalized, (ii) symptomatic, not hospitalized and (iii) asymptomatic | 12-24 weeks post COVID-19 diagnosis | Compare MRI measures of organ dysfunction at 12-24 weeks in survivors according to severity of prior COVID-19 illness: (i) hospitalized, (ii) symptomatic, not hospitalized and (iii) asymptomatic |
| Compare 12-week walk test results to the corresponding findings on MRI of brain, heart and lung at baseline | 12 weeks post COVID-19 diagnosis | Compare 12-week walk test results (distance and time) to the corresponding findings on MRI of brain, heart and lung at baseline |
