No concise answer available; the heart muscle once damaged, scars. However we now have evidence that it isn't that it "doesn't heal" it heals too slow to help us ---new findings show that help will come in the form of stem cells that rebuild the muscle!Here is the article;-DrRich
The news media has been reporting all week that scientists now have evidence that damaged heart muscle can repair itself. This is true, but any clinical benefit that might derive from this new knowledge is a long way off.
As reported by investigators from the New York Medical College in the January 3, 2002 issue of the New England Journal of Medicine, after a heart transplant, heart muscle cells from the recipient (i.e., the person receiving the heart transplant) can migrate to the transplanted heart, and can grow and replicate themselves there. This observation constitutes new knowledge, since it has always been thought that heart cells are incapable of regenerating themselves in any way. Based on this new observation, scientists are now speculating that there might be such a thing as a heart stem cell. (Stem cells are primitive cells that can differentiate into one of several types of tissue.)This finding is

Heart muscle cells are considered "Post-mitotic cells" - that means they do not undergo mitosis to replicate themselves. Since they cannot replicate, they cannot repair the heart when it is damaged. So, the answer is (2) "doesn't repair itself".
Best wishes and good luck.
