NPPB and COVID-19: Mc Rae et al. presented a biomarker, i.e., C-reactive protein (CRP), N-terminus pro B type natriuretic peptide (NT-proBNP), myoglobin (MYO), D-dimer, procalcitonin (PCT), creatine kinase-myocardial band (CK-MB), and cardiac troponin I (cTnI) based COVID-19 severity score to predict mortality in COVID-19 patients [29].
