We compared the changes in blood test of patients at baseline and onset of myocarditis and found that in addition to the significant decrease in ALC, NLR, C-reactive protein (CRP), lactate dehydrogenase (LDH), interleukin (IL)-6, IL-10, creatine kinase (CK), MB isoenzyme of creatine kinase (CK-MB), and brain natriuretic peptide (BNP) all increased significantly (Table 2). This evidence concerns the gene ALLC and myocarditis.
