Does Extreme Stress Cause Heart Attack?

Hi, can u have a heart attack From being extremely upset and under stress. I seem to be having what seems to be heart burn everyday, and several times a day. I eat Tums but doesn't seem to really work. I am having some personal issues at the moment,and very stressed. I get some heaviness in chest. I do have high blood pressure, I DO NOT smoke. Never have. I have heard of broken heart syndrome?????? Is that true??
