Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who have had a moderate to severe COVID-19 infection confirmed by RT-PCR.

Probably not a fit

Patients with contraindications to MRI or significant diseases that could affect their ability to participate may not benefit from this study.

What this trial studies

The C-MORE study is a prospective observational study that aims to characterize the prevalence of multi-organ injury among COVID-19 survivors after hospital discharge. It will utilize advanced magnetic resonance imaging (MRI) technology to assess the lungs, heart, brain, liver, and kidneys of 616 patients at 3, 6, and 12 months following the onset of COVID-19 symptoms. Additionally, the study will evaluate the impact of these injuries on quality of life, exercise tolerance, and mental health. By examining the relationship between persistent multi-organ damage and various factors, the study seeks to provide a comprehensive understanding of the long-term consequences of COVID-19.

Why it matters

Potential benefit: If successful, this study could lead to improved management and rehabilitation strategies for COVID-19 survivors experiencing multi-organ complications.

How similar studies have gone: Other studies have indicated the potential for multi-organ effects in COVID-19 patients, but this specific approach using longitudinal MRI assessments is relatively novel.
