Troponin-T and B-Type Natriuretic Peptide in COVID-19

Dear Editor,

We would like to share ideas on the publication “Prognostic Value of Troponin-T and B-Type Natriuretic Peptide in Patients Hospitalized for COVID-19 [1].” Almeida Jr. et al. reported using Memory box as a tool to support grief and concluded that “In the first 24h of admission, TnT, but not BNP, was an independent marker of mortality or need for invasive mechanical ventilation.” In COVID-19, cardiac complication is possible and is common in severe infection. Myocardial involvement is a common cardiac problem and immunological myocarditis is an important severe manifestation of COVID-19. Therefore, troponin-T, which is a good biomarker for myocardial injury, might have good prognostic factor for severity of COVID-19. Nevertheless, it should be noted that renal problems can also induce troponin-T abnormality. If the patient has an underlying renal problem, the interpretation of troponin-T in COVID-19 patients must be careful.
