  • Interestingly, this winter cardioprotective phenotype is associated not only with suppression of metabolic demand, but also with a fuel shift from myocardial carbohydrate to fatty acid (FA) metabolism. (duke.edu)
  • We feel that developing strategies to help 'switch' myocardial metabolism to resemble that naturally occurring in mammalian hibernators represents a transformative approach that could ultimately have an important positive impact in patients undergoing cardiac surgery and transplantation, as well as in victims of cardiac arrest, stroke, trauma and hypothermia, in addition to fundamentally advancing the field of nuclear receptor biology and myocardial substrate metabolism under extremes of physiology.
