Hibernating myocardium
Hibernating Myocardium
Hibernating myocardium (pronunciation: hi·ber·nat·ing my·o·car·di·um) is a term used in Cardiology to describe a state in which heart muscle cells reduce their function and metabolism to survive under conditions of insufficient blood supply, a condition known as Ischemia. The term is derived from the Latin hibernare, meaning "to pass the winter", and the Greek myo, meaning "muscle", and kardia, meaning "heart".
Overview
Hibernating myocardium is a condition that can occur when the heart muscle (Myocardium) does not receive enough oxygen due to a reduced blood flow (Ischemia). This can be caused by a narrowing or blockage of the coronary arteries (Coronary Artery Disease). The affected heart muscle may appear to be permanently damaged in medical imaging tests, but it is actually in a state of "hibernation" - it has reduced its function and metabolism in order to survive.
Clinical Significance
The concept of hibernating myocardium is important in the management of Coronary Artery Disease and Heart Failure. It is a potentially reversible cause of heart failure and may improve with treatments that restore blood flow, such as Coronary Artery Bypass Grafting (CABG) or Percutaneous Coronary Intervention (PCI).
Diagnosis
Diagnosis of hibernating myocardium can be challenging. It is often identified during a Stress Test, where the heart is made to work harder and beat faster. During this test, areas of the heart that are hibernating may not function properly. Other diagnostic tests include Echocardiography, Cardiac MRI, and Positron Emission Tomography (PET).
Treatment
Treatment of hibernating myocardium aims to restore blood flow to the heart muscle. This can be achieved through medications, Percutaneous Coronary Intervention (PCI), or Coronary Artery Bypass Grafting (CABG).
