Time---the longer the heart muscle goes w/out oxygenated blood, the more damage gets done.

Actually the lenght of time during which the heart muscle is deprived of blood and of course oxygen can determine the amount of damage, however it may also depend on the location of the blocked or damaged blood vessel to determine the size of the area.

A cardiac catheterization with a v-gram can determine where the heart attack occured and help in determining the extent of damage by the ventricular wall motion and ejection fraction( the amount of blood pumped from the left ventricle with each beat).

Where the damage is, the amount of time the heart is without blood supply to that certain area.

Once heart tissue is infarcted, it's dead. If it's merely ischemic, it still has a chance at recovery.
The difference between the two is the amount of time the tissue goes without sufficient oxygen.

Which blood vessel becomes blocked. If it is a main artery to the heart like the left anterior descending artery, than a large amount of heart muscle will die. If the blocked artery is only a small branch, then only a small amount will die.

i was tought the amount of damage definately depends on how much time there is between the start of the MI and how quickly it is treated/the person gets to the ER.

Infarction.
Myocardioal Infarction. It's dead tissue and to determine the amount of dead tissue and how deep, doctors may do an MRI with contrast.
