Pulmonary perfusion analysis of cardiac magnetic resonance imaging in patients with previous COVID-19 may help phenotype patients with advanced cardiopulmonary disease. Lung perfusion analysis was performed and results were correlated with clinical data in patients who were treated for COVID-19 at Johns Hopkins institutions. Older age and hospitalization for COVID-19 were found to be related to worse pulmonary perfusion, as measured by the perfusion parameter 50% max intensity, suggesting that one long-term sequela of severe COVID-19 that requires hospitalization, particularly in older patients, is a global bilateral decrease in the speed at which the lungs are perfused.
