Why the study?
Some patients experience persistent cardiac symptoms after hospital discharge following COVID-19 infection, but the long-term cardiac involvement in these patients remains unknown.
Does prior moderate or severe COVID-19 infection cause persistent cardiac imaging abnormalities in patients with persistent cardiac symptoms at 1 year?

Persistent symptoms may reflect subclinical LV dysfunction and fibrosis at 1 year; leaves open need for prospective CMR-outcome studies.
Does prior moderate or severe COVID-19 infection cause persistent cardiac imaging abnormalities in patients with persistent cardiac symptoms at 1 year?
Patients with persistent cardiac symptoms 1 year after COVID-19 hospitalization show evidence of reduced LVEF, increased ECV, and focal LGE on CMR compared to controls.
