Furthermore, according to HF aetiology, significant correlations between NFAT1 and MEF2 were obtained in both groups (ICM r = 0.382, p<0.05; DCM r = 0.585, p<0.01, respectively), and GATA4 protein only showed a significant correlation with NFAT1 in the ICM (r = 0.373, p<0.05). Here, NFATC2 is linked to hydrops fetalis.
