The occurrence of myocarditis was associated with increased creatinine serum (p < 0.001), increased NT-proBNP (p < 0.001), increased hs-troponin (p < 0.001), a decreased mean GLS (p = 0.004), and the need for mechanical ventilation (p < 0.001) (Table 4). This evidence concerns the gene NPPB and myocarditis.
