In this insightful episode of Parallax, Dr Ankur Kalra explores the emerging field of cardiac epigenetics with Dr Manuel Rosa-Garrido, assistant professor of medicine at the University of Alabama in Birmingham. Their conversation examines how the three-dimensional organization of DNA within the cell nucleus influences heart disease development beyond traditional genetic sequencing.

Dr Rosa-Garrido shares his pioneering work using Hi-C technology to map genome structure, revealing that DNA arrangement plays a crucial role in cardiac pathology. The discussion covers key concepts including chromatin loops, topologically associating domains, and compartmentalization—explaining how these structures regulate gene expression and how their disruption contributes to cardiovascular disease.

The episode explores practical implications for clinical practice, from early biomarker identification to potential CRISPR-based therapies that could target chromatin structure. Dr Rosa-Garrido outlines how this research could transform cardiovascular care within the next decade, offering new approaches to both inherited cardiomyopathies and environmentally-influenced conditions like atherosclerosis.

Valuable insights for cardiologists interested in precision medicine and the evolving understanding of how genetic architecture influences cardiovascular risk and treatment strategies.
