WebDiscussion. The term ‘myocardial hibernation’ was first coined by Rahimtoola when commenting on the results of the large randomised trials of coronary artery surgery.1 He envisaged a state of chronic coronary hypoperfusion, insufficient to cause necrosis but leading to a prolonged reduction in myocardial contractility; this could occur even in the … WebDuring hibernation, body temperature drops to only a few degrees above ambient temperature. The suppression of whole-body energy expenditure is associated with regulated, but not passive, reduction of cellular metabolism. The heart retains the ability to beat constantly, although body temperature drops to less than 10 °C during hibernation.
