I had a cardiac CT scan to measure coronary calcium index 5 years ago and my level was 0. I had one repeated last week and my number in now 323. I am a non smoker, on low dose BP meds and last BP was 110/70, 65 years old, female, PGF had heart attack, father may have had heart disease but not sure. My cholesterol is good with HDL sometimes as high as 70. I am a recovering alcoholic and that has been the only major change in my habits past 2 years. I am 9 months sober.
