Cardiovascular diseases (CVDs) are a group of non-communicable disorders of the heart and blood
vessels. Although lifestyle changes as well as pharmacological treatments and surgical interventions are available
in many countries, CVDs are still considered the number one cause of mortality worldwide. Hence, considering
that most CVDs are caused by genetic and environmental imbalances, micro-RNAs (miRNAs or miRs)
appear as a plausible therapeutic option for CVDs as they are able to regulate a wide number of genes due to
multiple target sites in different genes. Since miRNA-30 and -145 have been shown to play critical roles in the
cardiovascular system, acting as important regulators of many functions and biological processes, this review
focuses on summarizing recent findings on their involvement in CVDs, mainly as targets for therapeutic intervention.
Therefore, the biology, mechanisms of action and data on what has been discovered so far regarding
miRNA-30 and 145 as therapeutic targets for CVDs are presented.
