Abstract: Cardiac fibrosis is a vital pathological feature of various cardiovascular diseases, including myocardial infarction and heart failure. However, there have been few clinical interventions to treat cardiac fibrosis. Noncoding RNAs (ncRNAs) are a class of RNAs that do not encode proteins. ncRNAs participate in various cellular biological processes and regulate gene expression at transcription, post-transcription and epigenetic levels. Recent studies demonstrate that ncRNAs participate in the regulation of cardiac fibrosis by affecting the proliferation and transition of cardiac fibroblasts. ncRNAs can be used as potential intervention targets and biomarkers for cardiac fibrosis, provide new strategies and approach for treating and preventing fibrosis associated cardiovascular diseases. This review summarizes the function and mechanisms of ncRNAs in cardiac fibrosis.
