Epigenetics refers to heritable traits that are not a consequence of DNA sequence. Three classes of epigenetic regulation exist: DNA methylation, histone modification, and noncoding RNA action. In the cardiovascular system, epigenetic regulation affects development, differentiation, and disease propensity or expression. Defining the determinants of epigenetic regulation offers opportunities for novel strategies for disease prevention and treatment.
