Myocardial Blood Flow Quantified Using Stress Cardiac Magnetic Resonance After Mild COVID-19 Infection
Authors' conclusion
This study suggests that there are no significant abnormalities in rest or stress myocardial perfusion, and thus microvascular function, in individuals after mild COVID-19 infection.
Study context
- Population
- Individuals after mild COVID-19 infection (none hospitalized)
- Participants
- 30 vs 26
- Exposure
- Prior mild COVID-19 infection vs matched controls
- Prior COVID-19n = 30
- Controlsn = 26reference
- Outcome
- Myocardial blood flow (stress and rest myocardial blood flow (MBF)) and myocardial perfusion reserve by stress CMR
Methodological detailsmatched controls, Median time from infection to cardiac magnetic resonance (CMR) 5.6 (IQR: 4-8) months
- Matched controls
- Median time from infection to CMR 5.6 (IQR: 4-8) months
Main finding
As reported in the abstract
rMBF, sMBF and myocardial perfusion reserve
- No significant differences in rMBF, sMBF or myocardial perfusion reserve between the groups
- Prior COVID-19 vs Controls: P = 0.16
- Prior COVID-19 vs Controls: P = 0.91
- Prior COVID-19 vs Controls: P = 0.13
- Values mean ± SD as printed; unpaired t-tests
Observational data: associations, not effects.
Further findings
Symptoms (chest pain, shortness of breath, syncope, palpitations)
P < 0.001
