WebMyocardial hibernation represents a state of persistent regional contractile ventricular dysfunction in patients with chronic ischemic heart disease that is reversible with … WebMyocardial hibernation is viewed as a protective mechanism that helps to maintain myocardial integrity and viability by down-regulating contractile function as an adaptation to reduced blood flow. Myocardial flow is considerably heterogeneous. Consequently, oxygen supply to the myocardium is also heterogeneous.

WebApproximately 50% of the patients with chronic obstructive coronary artery disease resulting in chronic contractile dysfunction have hibernating myocardium and may benefit from … 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. WebHibernation is a condition of sustained reduction of contractile function in hypoperfused but viable myocardium, which improves upon reperfusion. Stunning is characterized by spontaneously reversible postischemic dysfunction despite completely restored perfusion. syntax to set background image in html
