Mild COVID-19 infection was not linked to longer-term heart damage, according to a JACC Cardiovascular Imaging study late last week. University College London researchers matched 74 SARS-CoV-2–seropositive and 75 seronegative healthcare workers, comparing cardiovascular health (6 months post-diagnosis for the COVID group). Cardiovascular magnetic resonance imaging and blood tests showed no difference between groups regarding inflammation, scarring, aortic stiffness, serum biomarkers, or the left ventricle size, muscle mass, or ability. Because of this, the researchers do not recommend screening non-hospitalized asymptomatic COVID-19 patients for longer-term heart issues. They also note that some of the COVID patients' abnormalities may not have been caused by COVID-19.
