I want to thank everyone in this thread for your posts and the excellent references that are included. I just had a CT evaluation and my Agatston score was 2082! It put me at the 97th percentile for someone my age (65). I just found my score from July of 2005. At that time, I was 50 years old and my score was 544. That placed me at the 90th percentile. But hey, at least I'm a top achiever in something...
The new score was a little frightening, but reading your stories, I've mellowed out a little. I'm doing everything I can to stay healthy. I eat a reasonable diet, keep my blood pressure under control, take a statin, don't smoke, and minimize alcohol consumption. I exercise most days of the week and try to avoid stressful situations.
I did have one stent placed in an OM artery in 2006. Over the years, I've had coronary catheterizations done to rule out additional blockages, and they've all indicated the plaque is primarily in the artery wall, and not causing issues.
I've been living very well with high calcium scores for 15 years. And I'm feeling pretty darn good now. So if you get diagnosed with a high score, don't panic, take care of yourself and hopefully you can stay healthy too.
I just want to back up the advice you got above from @654321, because you have not mentioned tests for parathyroid gland function. That gland controls calcium levels in the blood as it relates to calcium needs of various tissues in your body. I add my support for testing your parathyroid, starting with a simple lab test on blood drawn in the laboratory. The test gave me a lot of confidence in my primary care physician and cardiologist.
