Cardiomyocyte regeneration after infarction: changes, opportunities and challenges.

Myocardial infarction is a cardiovascular disease that poses a serious threat to human health. The traditional view is that adult mammalian cardiomyocytes have almost no regenerative ability, but recent studies have shown that they have regenerative potential under specific conditions. This article comprehensively describes the research progress of post-infarction cardiomyocyte regeneration, including the characteristics of cardiomyocytes and post-infarction changes, regeneration mechanisms, influencing factors, potential therapeutic strategies, challenges and future development directions, and deeply discusses the specific pathways and targets included in the regeneration mechanism, aiming to provide new ideas and methods for the treatment of myocardial infarction.
