Can you have a massive heart attack with no heart damage?

Yes, it is possible to have a massive heart attack but be left with no or minimal heart damage. Heart attacks caused by sudden blood clot formation in a coronary artery that completely blocks blood flow would lead to heart damage if blood flow were not rapidly restored. However, if the person with the blockage gets prompt angioplasty with a stent or a drug to dissolve the clot, major heart damage can be avoided.
