He would not have got angioplasty unless there was some narrowing or blockage of the coronary arteries would he? Very unethical of the docs to do otherwise. I think it is possible to have muscle spasms and/or cardiac problems. It has been my experience that the heart is always ruled out as precautionary measure and that of course the angiography is best as it represents a 'map' of the arteries so to speak.
