Peak hs-cTnT concentrations during hospitalization predicted the presence of abnormal cardiac findings 3 months after COVID-19 among survivors (geometric mean [95% CI]): 17 (13–23) ng/L and 11 (9–14) ng/L, p = 0.034, for patients with and without cardiac abnormalities respectively). Here, TNNT2 is linked to Abnormal heart morphology.
