I think I have been having heart mild heart attacks can you help me? 6 years ago I was diagnosed with having had a heart attack and an expanded heart. I have since stopped all of my bad habits but still have chest pain and sweats with confusion and nausea that last for 5 to 15 minutes then go away. I had that happen again 2 days ago and now my chest pain won t go completely away and I keep getting sick to my stomach and breaking out in sweats. Whats going on, I am average weight and 53 years old.
