Interestingly, We found that cTnI was strongly positively correlated with CRP (r = 0.704, p = 0.042) and LDH (r = 0.738, p = 0.037), and related literature [26–29] had reported that both LDH and CRP can be used as powerful predictors for early identification of patients with severe COVID-19. The gene discussed is TNNI3; the disease is COVID-19.
