Research Advances and Challenges of miR-223 in Cardiovascular Disease

Cardiovascular disease (CVD) is currently one of the most severe diseases endangering human health, encompassing myocardial ischemia syndrome, myocardial fibrosis, atrial fibrillation, and other conditions. MicroRNAs (miRNAs/miR) are a class of small non-coding RNAs that can bind to specific sequences and subsequently regulate post-transcriptional processing, translation, or epigenetic modifications, thereby modulating gene expression. Studies have found that miR-223 is associated with the occurrence and development of CVD and represents a potential specific therapeutic target. This article summarizes the relevant research on miR-223 in CVD, focusing on myocardial ischemia syndrome, myocardial fibrosis, and atrial fibrillation, and discusses its application prospects and challenges as a specific therapeutic target, providing new ideas for the diagnosis and treatment of CVD.
