Since the post you referred to is kind of old and I know the book swilkins1974 referred to, it's "Beat the Heart Attack Gene: The Revolutionary Plan to Prevent Heart Disease, Stroke, and Diabetes" by Bradley Bale , Amy Doneen, et al.

I have a story like many here -- unexpected crazy high CAC score despite good lifestyle and normal LDL over my entire life. The only red flag was a family history. I read the book swilkins1974 mentioned and it was very informative. I wish I had read it decades earlier. I also wish I hadn't bought into the seemingly implicit message that if you maintain a healthy lifestyle and have normal LDL you won't get atherosclerosis. I did nothing and my doctor did nothing until I had a CAC score in the 98th percentile at 60 years old. I did so much to protect my health and that book made me realize that I should not have, and frankly my doctor should not have, ignored the family history. In my worst moments, I am a little bit bitter about it.
