LV dysfunction in patients with COVID-19 stratified by high-sensitivity (HS) troponin level. The presence or absence of LV dysfunction, defined by LV ejection fraction (LVEF) < 50% or regional wall motion abnormalities, is shown in the group of patients with high-sensitivity troponin < 50 ng/L (left; n = 43) and ≥50 ng/L (right; n = 50). Of the 24 patients with some form of LV dysfunction in the elevated troponin group, nine underwent follow-up echocardiography, with the majority (n = 8) demonstrating resolution of LV abnormalities with the exception of one patient with previously documented LV dysfunction.
