The results of GSEA indicated that focal adhesion, dilated cardiomyopathy, ECM receptor interaction, TGF-β signaling pathway, GAP junction, pathway in cancer, calcium signaling pathway, MAPK signaling pathway, chemokine signaling pathway, GnRH signaling pathway, and hedgehog signaling pathway were mainly enriched in high-risk group (Fig. 10A). Here, GNRH1 is linked to dilated cardiomyopathy.
