Roles of microRNAs in cardiorenal syndrome

Cardiac and kidney diseases are intimately linked through numerous pathophysiological pathways, frequently exerting reciprocal influences on one another. This interconnection often culminates in heightened morbidity and mortality rates within the clinical spectrum of cardiorenal syndrome (CRS). CRS is categorized into five types based on the primary organ involved and the chronicity of the condition. Each type of CRS encompasses a complex array of pathophysiological mechanisms. In recent years, the field of microRNAs (miRNAs) has risen to prominence, playing a crucial role in the pathogenesis of a multitude of diseases. By uncovering novel therapeutic targets through the study of miRNAs that influence the expression of the CRS genes, the prognostic outcomes for patients could be significantly improved. This article provides a comprehensive review, examining the pathophysiological underpinnings of CRS, miRNAs alterations and their associated mechanisms in various forms of CRS, as well as the potential of miRNAs in precision medicine and the use of miRNAs for the diagnosis of the disease.
