Hyperglycaemia to heart failure: molecular pathophysiology, clinical manifestations, and novel therapeutic targets for diabetic cardiomyopathy

Peer-reviewed articles, original research papers, and review articles focusing on molecular mechanisms, signaling pathways, and therapeutic interventions related to DCM were included. Studies involving both experimental models and human subjects were considered. Data were extracted regarding metabolic alterations, key signaling cascades (NF-κB, PARP1, GLUT4, AT1R), and their association with cardiac remodeling, fibrosis, and functional impairment. The information was synthesized to illustrate the progression from metabolic imbalance to clinical manifestations and to identify promising molecular targets for therapy.
