My friend also had a reading of 0 calcium and had a massive heart attack a year later.
“My friend also had a reading of 0 calcium and had a massive heart attack a year later.”
I had a frighteningly high score on my CAC test (1200!), so my PCP referred me to a large heart-health hospital for a (color doppler) stress test (for what it’s worth, my treadmill performance was 50% higher than normal for my age group).
The chief cardiologist saw no abnormalities in any aspect of my heart circulation, valve performance, etc., and said that if I maintained proper weight, good BP, and took statins (I’m not - they caused crippling muscle cramps - but I’m doing other things), that my heart attack risk should be normal for my age.
He said that while CAC is a valuable indicator, it’s not an absolute...he said he’s got patients with a 0 CAC score who have overt cardiac disease and patients with a 5000 CAC score with no heart problems. He mentioned something about genetic polymorphisms but got called away before I could ask him to elaborate.
