Restoring Vagal Nerve Connection May Prevent Cardiac Aging

The Heart-Vagus Nerve Link
Experts at the Sant’Anna School of Advanced Studies in Italy have discovered a potential key to preventing cardiac aging: restoring the connection between the heart and the right vagus nerve. Their research, published in Science Translational Medicine, suggests that maintaining this connection is an anti-aging factor for the heart.
The study highlights the critical role of the vagus nerve, notably the right cardiac vagus nerve, in protecting cardiomyocytes – the muscle cells of the heart – and preserving cardiac longevity, autonomous of heart rate.
Multidisciplinary Approach to Research
This research represents a notably multidisciplinary effort, integrating experimental medicine and bioengineering to advance cardiovascular understanding. The work was spearheaded by the Translational critical Care Unit (TrancriLab) at the Center for Interdisciplinary Research in Health Sciences, led by Professor Vincenzo Lionetti, and the Institute of Biorobotics, directed by Professor Silvestro Micera.
Professor Lionetti explains that the loss of vagal nerve connection accelerates heart aging. Even a partial restoration of this connection can effectively counteract damaging remodeling processes and maintain healthy heart function.
Bioengineering Innovation: A Nerve Conduit
Researchers developed an implantable, bioabsorbable nerve conduit designed to stimulate and guide the natural regeneration of the thoracic vagus nerve at the cardiac level. This conduit provides a scaffold for nerve regrowth.
Implications for Cardiac Surgery and Transplantation
These findings suggest a potential paradigm shift in cardiothoracic and transplant surgery. restoring cardiac vagal innervation during surgical procedures may offer a proactive strategy for long-term cardiac protection, moving away from managing late-stage complications of premature aging towards preventative measures. This approach could considerably improve patient outcomes and quality of life.
