Again. Calcium buildup in arteries causes more deaths than anything else.
Nope, even that part is not correct. Calcium in arteries indicates established, already existing CVD. Calcified plaques are more stable than non-calcified plaques (non calcified plaques cause STEMIs and strokes). At best, the calcium in arteries is a
correlation of underlying established disease. It is not
causal.
I've read that cholesterol itself its not measure of how bad you're arteries are, but the build up that you mention here.
The cholesterol contained in your lipid panel shows the concentration of lipids in the blood. It doesn’t say anything about the current state of your arteries. The non HDL-c (LDL-c + triglycerides/5) is a surrogate marker for apoliprotein-B, a protein present on all artery clogging particles in the blood. It’s like how your a1-c test is a bio marker for overall blood sugar levels. CVD takes decades of elevated Apo-B to manifest, which is why short term studies and anecdotal CAC scores are useless.
