Hey all,

I'm just wondering if anyone can explain the key difference btwn myocardial stunning and ischemic preconditioning?

From what I know, preconditioning is just training the cardiac myocytes rely on less oxygen.

Myocardial stunning involves ischemia for a short period of time before any irreversible damage occurs.

So does this mean stunning is a pathological event, whereas preconditioning is a protective event? Is there actually a difference?

Thanks!
