Sorry, I meant mom 655 instead of stressball heart. Also, if you meant the stess test w/dye is the angiogram, then please disregard the previous post. Best wishes.
Stress test even w/dye is not always accurate. You can have a false negative. With your family history I would ask the Doc to do an angiogram or you can also go for a second opinoin. Just my thoughts. Good luck.
The symptoms could be related to heart spasms of the coronary artery system. The condition may not be diagnosed with the tests you have been given unless the symptom occurs during the test. The stress test would be with perfusion to evaluate if there is any induced ischemia (blockage).
Hope this helps, and if you have any further questions or comments you are welcome to respond. Take care,
Ken
