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
