My cardiologist said that the Calcium is not simply deposited in your arteries because it happens to be in your bloodstream and goes THERE instead of your bones; it’s a very complex reaction which has more to do with the make-up of the atherosclerotic plaque itself.
In other words, you don’t get osteoporosis from calcium getting re-routed somewhere else, nor is calcium in the coronary arteries a consequence of that. Hope this helps!
