The Claim
Sheet-like calcification at the outer border of human carotid plaques is exclusively associated with the fibrous cap atheroma phenotype.
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.
In human carotid artery plaques, a specific sheet-like calcium pattern at the outer edge is consistently found only in plaques with a fibrous cap atheroma structure.
See the scientific wording
In human carotid plaques, sheet-like calcification at the outer border is exclusively associated with fibrous cap atheroma phenotype, suggesting this specific calcification pattern may coexist with high-risk features despite its structural appearance.
White blood cells invade the plaque and break down the protective fibrous cap, making it thin and weak. At the same time, these cells trigger bone-like cells to form a flat layer of calcium on the outer edge of the plaque. This calcium layer forms only when the cap is already thin and inflamed, so the plaque looks stable on the outside but is still dangerous inside.
What the research says
1 studyThe study found that all 11 segments with sheet-like outer border calcification were classified as fibrous cap atheroma, a high-risk phenotype. This 100% association indicates this calcification pattern is not protective and may coexist with inflammation-driven instability.
