In this prospective study of patients who were presented with NSTEMI or STEMI, we found that the NR3C2 rs2070950 and rs4635799 gene polymorphisms were significantly associated with the left ventricular remodeling, and the rs5522 gene polymorphism was significantly associated with cardiac conduction disorders in the post-AMI period. Here, NR3C2 is linked to heart conduction disease.
