I went through a similar process, was prescribed and had some extremely serious side effects that put me in the hospital. When in the hospital, they did an angiogram and it came back completely clear. The angiogram is the Gold standard. I’m very skeptical now of the CAC. I do not believe it to be relevant for people who exercise heavily and have normal numbers for BMI, blood pressure, etc. I was very anxious about all of this for 4 months until last week when I had the emergency angiogram.
