Liver enzymes (AST and ALT) and CRP were markedly increased in ASS patients with myocarditis compared with those without myocarditis [97.5 (40.0–194.0) vs 27.5 (21.0–34.25) U/l, 136.5 (32.25–194.0) vs 212.5 (12.0–33.25) U/l and 7.0 (1.7–15.75) vs 1.85 (0.5–2.86) mg/l, respectively (P = 0.007, P = 0.006 and P = 0.011, respectively). This evidence concerns the gene GPT and myocarditis.
