Abstract: The use of a Wnt inhibitor Wnt-C59 in the preparation of a drug for treating SCN5A mutation-induced dilated cardiomyopathy (DCM) is provided. With SCN5A genotype detection as a breakthrough point, a Wnt pathway-specific inhibitor Wnt-C59 is used to inhibit the abnormal activation of the Wnt?-Catenin pathway caused by SCN5A gene mutation, thereby improving the prognosis of cardiac function in a patient with SCN5A gene mutation-induced DCM. In experiments, aging and adriamycin-induced DCM models are constructed, and the therapeutic effect of Wnt-C59 on DCM is detected through indexes such as changes in cardiac function and activation of related signal molecules, which provides a theoretical basis for use of Wnt-C59 in the clinical treatment of DCM. A new treatment method for SCN5A mutation-induced DCM is provided to bring dawn to such patients and has promising application prospects.
