Good morning,
I would absolutely demand an angiogram and I'll give you my reason.
I am not overweight, work out 3-4x a week, total cholesterol of 102 (all cholesterol types are, and have been, well in line). EKGs, stress tests, etc always came out perfect. I've been a vegetarian for over 10 years. The model of good health, right? Wrong.
Took a calcium heart scan and my score was 2397!
Long story longer - after an angiogram it was discovered that I had 4 arteries over 90% blocked each. Cardiologist said a fatal heart attack was imminent.
Ended up having quadruple bypass surgery, which saved my life.
Please demand an angiogram.
