WebThe detection of dysfunctional, hibernating myocardium that can be improved by revascularization is important in the management of patients with ischemic heart disease. Hibernating myocardium results from the functional adaptation of the myocardium to reduced resting myocar-dial perfusion. PET with F-18 FDG is widely used in the WebMar 1, 2005 · In conclusion, hibernating myocardium is characterized by a delicate balance of matched reductions in myocardial blood flow and function. However, the acute perfusion-contraction matching during short-term hibernation is not necessarily sustained over more than several hours.
