<s>[INST] I am a 40 year old woman, sedentary (aka lazy), 135 lb.s. On Friday night had some kind of heart thing - it hit nearly every symptom of a heart attack. It was not anxiety, it would go away for 10 - 15 minutes and then come back - lasted hours - gradually getting worse. In retrospect should have gone to er, but didn t (I also had over 20 gall bladder attacks before I got it removed - who has time???) Monday - 4pm doctor s office took bp 139/98. My normal bp is 90ish/60ish. Went to doctor Wednesday (today) and it was 105/70...The nurse practitioner ran the EKG and it was normal. She didn t say much, ordered blood tests (but not many), chest x-ray and Echo. But she also looked like she didn t believe me. Now my chest is getting tight again. [/INST] Hi,If ECG was normal, then it wasn't a heart attack, it may be angina, or other pain related to stomach or spine. Don't worry. Just wait your echo appointment, talk to your doctor to have a stress test as well, it will show, if there are some heart problems.Take careCome back if you have any further questions </s>
