[Troponin-T and n-terminal pro-brain type natriuretic peptide plasma levels and its relationship with mortality in COVID-19].

Hipertens Riesgo Vasc 2022 Apr 28. Epub 2022 Apr 28.

Hospital Escuela Eva Perón, Granadero Baigorria, Santa Fe, Argentina.

Introduction: Cardiovascular compromise in coronavirus disease 2019 (COVID-19) does not necessarily present with the classic symptoms described in myocarditis. There is growing evidence demonstrating subclinical cardiovascular compromise in the context of the intense inflammation unleashed, the cytokine storm involved, the baseline prothrombotic state, and the consequent endothelial dysfunction. We set out to analyse whether Troponin-T (TT) and the amino-terminal fraction of pro-brain natriuretic peptide (NT-proBNP) determined at hospital admission, are related to mortality during the hospitalization of these patients.
