Detailed Answer:
Hello!
I read carefully your query and understand your concern.

The situation you described above (hibernating myocardium and no irreversible structural damage to myocardium) is seen when there is a low blood flow in heart ,insufficient to complete the needs of myocardium for oxygen.
This is called Myocardial Ischemia and it occurs when blood flow to your heart muscle is decreased by a partial or complete blockage of your heart's arteries (coronary arteries). The decrease in blood flow reduces your heart's oxygen supply.
A sudden, severe blockage of a coronary artery may lead to a heart attack.

But it isn't a heart attack because the blood supply is sufficient to keep the heart cells alive.
If there is complete blockage of heart's arteries ,the area supplied from this artery will die and it is called Heart attack.

So with the sentence ''There is no irreversible structural damage to myocardium '' means that the episode of myocardial ischemia that happened didn't cause damages in heart muscle,the blood supply even why decreased was enough to keep heart cells alive.
So it wasn't a heart attack (total blockage of an coronary artery ) but it was an myocardial ischemia (partial blockage of an coronary artery).
The same situation is observed in a totally blockage of an coronary artery (heart attack) if there is an immediate treatment and intervention and the revascularization of the blocked artery is achieved soon.

Hibernating myocardium or stunned myocardium is a state when the affected area of the myocardium doesn't contract normally.This state is seen in chronic ishcemia (in decreased blood supply to the heart) or the time after the reperfusion of the area.
Hibernating myocardium is ischemic myocardium supplied by a narrowed coronary artery in which ischemic cells remain viable but contraction is chronically depressed.

So:There was no heart attack ,but an episode of myocardial ischemia.
There was no damage to the heart tissue but the affected area of the myocardium has a depressed contraction because as a result of decreased blood supply the affected cells don't function normally.

Hope it was of help.
Let me know if you have other questions or doubt to clarify.I will be happy to assist you further.

Kind Regards!

Dr. Rovena Muralti,
Thank you, so kindly for contributing to my questions.

I did have a 95% blockage and had a stent put in with great results.
There was a 41% infraction and now a 70% infraction.

I did read in the records a stunt myocardial. So I googled it and found hibernating myocardial.
I thought I had a heart attack, but reading about hibernating or stunt it seems I did not have a heart attack.

Brief Answer:
You are welcome!

Detailed Answer:
Hello again!

You are welcome.It is my pleasure to answer your questions.

The fact that you have chronic ischemic heart disease and you have a stent put in ,explains stunned myocardium.
The fact that you have a stent put on and there is no irreversible structural damage to myocardium is a good thing.This means that you have ischemic disease that explains stunned myocardium but your heart muscle isn't damaged.

The blood supply from the blocked artery (95%) was very decreased but it was sufficient to keep the cells alive (but not sufficient to provide a normal function of these cells which explains stunned myocardium).
If this artery was totally blocked (100%) then the heart muscles supplied from it would have died and you would have suffered a heart attack.

Hope my answer has helped.
Take care!
