Furthermore, there was no statistically significant differences for EF and FS between pre-treatment (mean EF 69.3±3%, FS 38.6±2.4%) and post-treatment (mean EF 69.6 ±2.8%, FS 38.8±2.3%) measurements in the study group (p=0.768 for EF, p=0.698 for FS), in moderate/severe carditis group (p=0.59 for EF, p=0.29 for FS) and mild/no carditis group (p=0.922 for EF, p=0.748 for FS).
