Patient-Level Perivascular Adipose Tissue Density Aggregation and Plaque Progression: Plaque-Free vs Plaque-Adjacent Segments.
BACKGROUND Perivascular adipose tissue (PVAT) density on coronary computed tomography angiography (CTA) reflects pericoronary inflammation, but measurements adjacent to existing plaques may be confounded by local inflammatory signaling from the plaque itself-a form of reverse causation. Whether systematically comparing...
