@seniormed one issue to keep in mind when relying on the heart scan is that it doesn't measure something called soft plaque. I guess the only take-away is that the scan is only a part of necessary testing. I mistakenly thought the scan was the definitive answer to arterial plaque health question. As @seniormd recommended, there are numerous other tests necessary for a firm answer to the question.

@seniormed
I do plan on asking Dr for that. Thank you.
