depression
"I had a Septal infarct at age 46 last year which brought on overwhelming depression post recovery. Not knowing I had had the heart attack (put it down to terrible upper epigastric pain). I suffered in bed with my own concoctions and obviously made it through this period.

I went to the doctors two weeks later with a feeling of major depression and did not inform her of the abdominal pain prior to this (didn't feel related). She started me on 50mg Pristiq daily that made me feel much better in one week and my mood continued to improve over the next 3 months to better than I had felt in such a long time. I still take Pristiq (1 year later) because I dread falling back into the major depressive episode I had even if it was related to the Infarct."
