Yes! I found out I had a CAC of 1100 when I was 61, six years later it is 1300. As long as your husband is asymptomatic there is nothing more to do than what you are doing right now. It is stressful at first, but you learn to live with it. Enjoy life and work on that bucket list.

For 6 yrs my cardiologist ordered a stress test every year that always showed everything was fine. They would not give me a catherization because the stress test always said everything is normal. Went back and saw another doctor in the group after yet another stress test. He looked at the results and said what are you doing here, everything is fine. Told him over the past 6 years I was dizzy and had passed out in shower in gym several times after a workout. That is the reason why so many stress tests, that always showed everything was fine. He ordered a calcium score test and when I went back for results he told me this test probably saved my life. My score was 960 and because it was high he was able to order a catherization for the next day.. results were that my left aortic was 87 % blocked and the inserted 2 stents. The doctor said it is called the “Widow Maker”. I was a walking time bomb for all the years the stress test said everything was fine !!

Was his pth tested?

My CAC Score went from 378 to 798 in 4 years. I am 79 but no heart symptoms, am active and overall very healthy. Passed two stress tests with flying colors. Then had them test me for Lipoprotein (a) [Lp a] and it was over the roof high at 283 nmol/L. Luckily, my high sensitive CRP is very low which says low inflammation so that is helpful to lower my risks. I take a lot of supplements and have a strong immune system. You might want to get your Lp a tested. The two together is very high risks but there are diet and lifestyle changes that look attractive until an FDA approved medicine is available; probably not until 2026.

In mid- to long-term follow-up, statin therapy increases the CAC score as documented by serial non-contrast cardiac CT, suggesting that the plaque-stabilizing effect of statins may be reflected in a higher CAC score [8,9].

I agree with your cardiologist, no need for angiogram.
Don’t go for calcium score test again , statins increase calcium score .

I’m nearly the same as your husband: 68 years old, non smoker, bmi of 24, on statin (80 mg) for 20+years and zetia for more than 15, and my calcium score is 843. Passed the stress test ecg, and echocardiogram with no findings.

My MD added Repatha after the calcium score which has dramatically lowered my LDL and Lipo(b), and I exercise daily, eat a plant based diet, and hold my breath
