The Claim
In human carotid atherosclerotic plaques, segments with little or no calcification are associated with moderate to high levels of leukocyte-driven inflammation and exhibit a fibrous cap atheroma phenotype, which is histologically linked to increased rupture risk.
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.
Human carotid plaques without calcification show higher levels of leukocyte-driven inflammation and a fibrous cap atheroma structure, which are histologically associated with a higher risk of rupture.
See the scientific wording
In human carotid atherosclerotic plaques, segments with little or no calcification are frequently associated with moderate to high levels of leukocyte-driven inflammation and are more likely to exhibit a fibrous cap atheroma phenotype, which is histologically linked to increased rupture risk, suggesting that non-calcified plaques may represent a high-risk subgroup not identifiable by calcification imaging alone.
Immune cells enter the artery wall and release enzymes that break down the protective layer over the fatty core, making it thin and weak. When this layer is thin and the plaque has little calcium, it is more likely to burst and cause a stroke.
What the research says
1 studyPlaques in the neck arteries that don’t show calcium on scans often have lots of immune cells and are more likely to burst — which can cause strokes. So, just looking for calcium misses these dangerous plaques.
