Non-coding RNAs in cardiac remodeling and heart failure.

Heart failure is a leading cause of death in industrialized nations especially in an aging population. The recent improvements in cardiac revascularization therapy reduced death rates because of myocardial infarction but steadily increased the number of individuals developing cardiac remodeling and heart failure in the future. Conceptual novel approaches entering the clinics to treat cardiac remodeling and heart failure remain scarce. MicroRNAs emerged as powerful and dynamic modifiers of cardiovascular diseases. In this review, the current approaches using microRNAs as novel diagnostic and therapeutic strategies for cardiac remodeling and heart failure are highlighted. Other gene regulatory mechanisms presented include long (>200 bp) noncoding RNAs that function as an additional regulatory machinery of the genome controlling both transcriptional and post-transcriptional events also in the cardiovascular system.
