I would just like to add don't wait for the pain in the jaw I have had 2 heart attacks and never experienced jaw pain. For me it is always arm and shoulder pain that radiates to back and accross shoulder blades and cold sweats. I almost always have these same symptons sometimes not the sweating and sometimes have dry heaves. I have had 2 heart attacks and lost track of stints but over 17. Now have pacemaker and feeling better
