Morphological predictors of arterial remodeling in coronary atherosclerosis

Abstract

Background — Although arterial remodeling in atherosclerotic arteries affects luminal patency, the role of plaque components has not been systematically studied. Methods and Results — Coronary segments (n=2885) were harvested from the hearts of 36 patients who died of severe coronary artery disease after perfusion fixation. Remodeling was determined by morphometric analysis of 657 sections selected as reference segments and 1318 segments with atheromatous plaques. Atherosclerotic plaques were identified as fibroatheroma, thin-cap fibroatheroma, intraplaque hemorrhage with or without rupture or erosion, or total occlusion. Plaque components consisted of calcification, lipid core, macrophage burden, and fibrosis. There was no correlation between plaque area and lumen size in proximal arteries, unlike middle and distal segments, which demonstrated a significant correlation. Marked expansion of the internal elastic lamina (IEL) occurred in plaque hemorrhages with or without and thin-cap fibroatheroma (vulnerable plaque), whereas in erosions and total occlusions there was shrinkage of the IEL. Macrophage burden, lipid core size, calcium (in fibrous plaque and lipid core), and medial atrophy were all associated with positive remodeling; fibrous areas, however, were negatively associated with remodeling. Conclusions — Inflammation, calcification, and medial thinning are primary determinants of positive remodeling, which appears to be a feature of plaque instability.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
