I think this is a tough call. If you are genuinely doing everything right and not having symptoms, then you could argue that there's little benefit. I thought I was doing everything right, got a CT scan because some calcifications in my iliac arteries showed up on an x-ray, and my CAC score was in the 98th percentile for my age and gender. I have a family history of heart disease. This was frightening. I tried to pin-down exactly what kind of diet I should be on. Honestly, I've made a few tweaks, but I was genuinely doing almost everything right. I did go on statins.

It does weigh on my mind. I think it's a real stressor. Sometimes I complete some job or whatever, and see that the stress of the job was more than I realized. I'm lighter and don't do stress-related things like drink coffee or eat a sweet or wake up stressed out at night. But before I complete the job, I wouldn't have said I was under stress. I think it's like that, but it will never go away. It has gotten better over time.

That said, for me, I think it's been better to know. I've made some modifications to try to improve my chance of survival. I carry aspirin around now. I make sure I have a phone or Apple Watch with me on runs. (I live in a rural area and I got a new iPhone for its ability to make satellite emergency calls. I'd probably still die, but I think I'd at least have hope in my final moments and that seems big.) As I mentioned, I made some tweaks to my diet and went on statins. I always have exercised and enjoy it, but I recognize now I have to be more serious about my consistency.

So you have to decide for yourself whether you believe you can live with the stress of knowing (or now not knowing) and whether you could make positive changes based on the results. If you trust your PCP, then that's a mark in favor of listening to him/her. It's a personal decision.

Good luck!!! Stay positive whatever decision you make!! If you decide to do it and you get a high score, come back and get the great experience and support of the folks on this forum.
