TNNT2 and COVID-19: Log-transformed concentrations of hs-cTnT measured 3 and 12 months after COVID-19 were associated with the presence of cardiac abnormalities (P < 0.001 for both), and this association persisted after adjusting for age and sex (unstandardized beta (B) 0.34 (95% CI 0.13–0.55), at 3 months and B 0.30 (95% CI 0.87 − 0.52) at 12 months).
