Why? Just why?
“A CAC score of 1–10 represents minimal calcified plaque and should not be considered diagnostic of coronary artery disease.”
— SCCT/AHA/ACC Expert Consensus, JACC Imaging, 2018"
1. A 3 CAC is near the measurable floor and treated the same as a 0 by most physicians. In fact it recently surveyed that 65% - 70% physicians treat it the exact same as a 0 regarding statin recommendations. You can look that one up on your own. Actually, you can look up both surveys.
2. A 3 does NOT equal a 3% risk over 10 years. Where did you get that number? MESA shows for a CAC of 1-10 that it indicates a 1-1.3% risk over 10 years, with a 0 score as high as 0.8%. Essentially no difference. And 3, if actually valid, is at the very bottom of that range.
3. CAC has a statistical variability of plus/minus 2%-5%. Up to HALF of those who get a second CAC after showing 1-10 score measure 0 on the next scan. My point is that we're in the noise here.
The test VERIFIED that I have no meaningful disease whatsoever. And that's a 5-10 year indicator. I like the verification.
The goal of my post was to WARN patients about what happened to me. As we've seen in the responses, many experienced the same thing...a PA/Doc putting them on statins without considering the one test that diagnosis actual disease. Remember, I had to self-educate before I realized that my artificially high clinical blood pressure alone put me over the threshold of "recommending a statin" using the blunt force ASCVD. I did the CAC to satisfy my own curiosity. A lifetime of CAC tests is about equal to ONE MAMMOGRAM SERIES worth of radiation. No measurable cancer risk. Thankfully it serendipitously showed the PA that she tried to "put me on a program of statins" without justification. I didn't throw it in her face. I simply asked for a CAC referral, and she interpreted the results. She knows what she did. Hopefully she learned from it. Hopefully docs who read but didn't post, and who aren't as caring or careful as you, also learned from this discussion. I do genuinely appreciate your input on this.
