I have a 255 CAC score - just found out six months ago after some blood tests that showed high glucose, high cholesterol/LDL, and a terrible family history of heart disease- and also passed a stress test and told I had no blockages. I decided I should have a CT angiogram (non-invasive X-Ray of the arteries) to make sure which came back a couple of days ago that I have an approximate 50 percent blockage in my LAD. The cardiologist also ran a blood flow test (FFRct) and it showed restricted blood flow in that area. I will be seeing the cardiologist at UCLA tomorrow to go over what this all means but I'm glad I went beyond my standard of care cardiologist who told me I was fine after the stress test and instead, saw a research cardiologist who specialized in CAC.
