Abstract (original English)

Myocardial infarction (MI) remains the leading cause of death worldwide. Cardiomyocytes, being terminally differentiated cells, have limited regenerative capacity. Following an MI, myocyte necrosis and ventricular dilation can lead to heart failure. While current treatments for heart disease-such as pharmaceuticals, coronary interventions, coronary artery bypass grafting, cellular therapy, and heart transplantation-offer some relief, their effectiveness is limited, particularly in patients with severe myocardial damage. Recent advancements in cardiac tissue engineering have introduced a range of materials aimed at repairing the heart, with conductive hydrogels emerging as a promising approach. These materials, which include metallic nanomaterials, conductive polymers, carbon-based conductive materials, and other specialized types of conductive substances, exhibit excellent electrical conductivity, tunable mechanical properties, and biomimetic features. As a result, they are increasingly being considered for myocardial repair. This review explores the application of conductive hydrogels in treating myocardial infarction, highlighting recent research in various types of conductive hydrogels. These are categorized by their nanomaterial composition, including hydrogels designed for cell culture scaffolds, patch-type hydrogels, and injectable conductive hydrogels. Additionally, elec
