Assessment of AVMC severity. Male BALB/c mice were infected with CVB3 on day 0. The survival rates (A) and bodyweight changes (B) of mice in the control (n = 10) and AVMC (n = 18) groups were monitored daily until day 7. C Values of HW/BW in two groups were recorded on day 7. D Representative images of myocardial histopathology H&E staining in two groups (magnification × 200 and × 400). E Cardiac pathological scores in two groups. Each point represents an individual mouse. ^*P < 0.05, ^**P < 0.01, compared to control group
