2.07 Hibernation and Stunning

In this episode, we explore the concepts in myocardial hibernation and stunning. What is the difference between myocardial stunning, hibernation, and scar? What is considered viable and what is not? What cellular adaptations occur in the process of hibernation? What pattern of rest perfusion, stress perfusion, and FDG metabolism on FDG PET imaging would indicate hibernation instead of scar? What would a hypokinetic->better->worse response vs a hypokinetic->better->worse response imply on dobutamine stress echocardiogram? Tune in for answers to these questions.
