Ejection fraction and volumetric assessment
LV and RV ejection fraction (EF) were noted in 4 studies
[102,104–106]. In a study of 100 patients, and 50 controls,
patients who recovered from COVID-19 had lower LVEF, RVEF, and higher
left ventricular mass [102]. This was duplicated in another study of
10 patients where 2 had depressed LVEF with apical ballooning suggesting
a takotsubo pattern and 3 patients having mildly reduced EF[104]. In
another study of athletes recovering from COVID-19 compared with
controls, RVEF was significantly reduced in the COVID-19 group
[106].
