Yup. That's what a heart attack does...damages the heart. When I had those worst pain you could ever imagine heart attack symptoms the angio showed no heart damage, so no heart attack, no blockages, so no stents needed, but the arteries and veins were swollen and a pulminary vein was being pinched closed every beat which was caused by a reaction to a med. Same symptoms and, I'm told, feeling of a heart attack. I've had all sorts of painful stuff...broken bones, etc...but that was all childs play compared to the heart. Felt like God himself was trying to crush me with his hands. I wish I could have passed out.
