The results showed that the increased hs-cTnI (adjusted HR, 4.74 [95% CI, 3.05–7.35]; P<0.001), CK-MB (adjusted HR, 2.17 [95% CI, 1.56–3.01]; P<0.001), CK (adjusted HR, 1.80 [95% CI, 1.28–2.53]; P<0.001), (NT-pro)BNP (adjusted HR, 5.67 [95% CI, 2.97–10.82]; P<0.001), and MYO (adjusted HR, 2.74 [95% CI, 1.82–4.13]; P<0.001) were still significantly associated with higher risk of all-cause mortality of COVID-19 (Table S8). This evidence concerns the gene TNNI3 and COVID-19.
