I was diagnosed with 1,005 atherosclerosis end of January (2025). At 64, it shocked the heck out of me. I haven't smoked in more than 25 years, but the diagnosis was enough to shock me into action. Excercise (walks 3-4 miles non stop per day, a bit of light weights, and diet (as best I could, mainly fish and chicken, salads, with only the odd red meat). I went from 175 lbs (80 kilos) down to a stable 155 lbs (70 kilos) in 5 months. I'm still asymtomatic, but I have been so bummed out by such a diagnosis, that I finally bit the bullet and had a CTA (with contrast dye) - against doctors recommendations due to having no symptoms. Good and bad came out of that. The good was that my LM has very little calcium and no stenosis, the LAD has 10% in one small part and 40% in another small part, while the RCA has 40-50% in one spot. The bad (weirdness) was in just 7 months, despite all the diet and exercise, the CAC score increase by 30%! Now 1,350! What?
