Outcomes of Cardiovascular Magnetic Resonance Imaging in Patients Recently Recovered From Coronavirus Disease 2019 (COVID-19)
Question: What are the cardiovascular effects in unselected patients with recent coronavirus disease 2019 (COVID-19)?
Findings: In this cohort study including 100 patients recently recovered from COVID-19 identified from a COVID-19 test center, cardiac magnetic resonance imaging revealed cardiac involvement in 78 patients (78%) and ongoing myocardial inflammation in 60 patients (60%), which was independent of preexisting conditions, severity and overall course of the acute illness, and the time from the original diagnosis.
Meaning: These findings indicate the need for ongoing investigation of the long-term cardiovascular consequences of COVID-19.
Association of Cardiac Infection With SARS-CoV-2 in Confirmed COVID-19 Autopsy Cases
Question: Can severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) be documented in cardiac tissue of coronavirus disease 2019 (COVID-19) autopsy cases?
Findings: In this cohort study of 39 autopsy cases of patients with COVID-19, cardiac infection with SARS-CoV-2 was found to be frequent but not associated with myocarditis-like influx of inflammatory cells into the myocardium.
Meaning: Among individuals with cardiac infection, overt myocarditis was not observed in the acute phase, but the long-term consequences of this cardiac infection needs to be studied.
