The Claim
In adults with elevated coronary artery calcium (CAC >100 Agatston units), higher levels of high-density lipoprotein cholesterol (HDL-C >40 mg/dL for men, >50 mg/dL for women) are associated with a 38% lower risk of atherosclerotic cardiovascular disease but not with reduced mortality, indicating that HDL-C may have a more specific role in preventing heart attacks than in extending life in this population.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
For people with already high calcium buildup in their heart arteries, having higher levels of 'good' cholesterol seems to lower their chance of having a heart attack or stroke—but it doesn’t seem to help them live longer.

In adults with elevated coronary artery calcium (CAC >100 Agatston units), higher levels of high-density lipoprotein cholesterol (HDL-C >40 mg/dL for men, >50 mg/dL for women) are associated with a 38% lower risk of atherosclerotic cardiovascular disease, but not with reduced mortality, suggesting HDL-C may play a more specific role in preventing heart attacks than extending life in this population.
What the research says
1 studyThe study found that adults with clogged heart arteries who have higher 'good cholesterol' (HDL) are less likely to have heart attacks, but it didn’t help them live longer — just like the claim says.
