In this study, we investigated the relationship between blood parameters (liver and kidney function tests, lactate, and D-dimer), infection parameters (CRP, lymphocyte count, ferritin, and albumin), and cardiac parameters (creatine kinase-myocardial band (CK-MB), troponin, and brain natriuretic peptide (BNP)) with intensive care unit (ICU) admission and six-month mortality. This evidence concerns the gene CRP and infection.
