KLF15 and myocardial infarction: Currently, the association between circadian rhythm, KLF15, and myocardial infarction is unclear, thus this paper reviews how circadian rhythm influences the role of KLF15 in myocardial infarction, aiming to reveal the association between circadian rhythm, KLF15, and myocardial infarction, and to explore the underlying mechanisms, to provide new theoretical insights and therapeutic strategies for the clinical treatment of myocardial infarction.
