Overview. A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don’t get enough oxygen. This happens when blood flow to the heart muscle is blocked.
Hereof, can a damaged heart repair itself?
But the heart does have some ability to make new muscle and possibly repair itself. The rate of regeneration is so slow, though, that it can’t fix the kind of damage caused by a heart attack. That’s why the rapid healing that follows a heart attack creates scar tissue in place of working muscle tissue.
