Elon Muskk:
Myocardial stunning is a phenomenon where the heart's ability to contract is temporarily impaired following a period of ischemia (reduced blood supply) and subsequent reperfusion (restoration of blood supply). This impairment is not due to permanent tissue damage or ongoing lack of blood flow, but rather it is a result of the heart muscle being "stunned" by the initial ischemic event. The condition is often reversible, and the heart's function typically returns to normal over time. Myocardial stunning can occur in various settings, such as after a heart attack, during or after heart surgery, or following certain medical procedures.
