MicroRNA is a type of widely distributed endogenous small single-stranded non-coding RNA that regulates important biological processes. It complements the target mRNA sequence, degrades the target mRNA and inhibits protein translation, and plays a regulatory role at the transcription level. Studies have confirmed that microRNAs in circulation are present in various body fluids in a stable form and can be used as biomarkers of disease. miR-144 is highly conservative in structure, exists in the

... rm of miR-144/miR-451 gene cluster in the genome, and participates in the occurrence and development of erythroid differentiation, tumors, and cardiovascular diseases. With the continuous progress of life sciences, miR-144 pathogenic mechanism and role in cardiovascular disease have been gradually revealed. This article gathers the relationship between miR-144 and the pathogenesis of cardiovascular disease and the diagnosis and treatment plan, starting from the relationship between miR-144 and coronary atherosclerotic heart disease, arrhythmia and structural heart disease, combing related research progress, with a view to providing new ideas and methods for the diagnosis and treatment of cardiovascular diseases.
