Plaque Volume

Meaning

Plaque volume is a quantitative metric, typically measured via advanced imaging techniques like Intravascular Ultrasound (IVUS) or Coronary Computed Tomography Angiography (CCTA), that represents the total spatial extent of atherosclerotic material accumulated within the lumen of an artery. This measurement is a direct, tangible indicator of the burden of cardiovascular disease and a critical prognostic factor for future cardiac events. Increased plaque volume signifies chronic endothelial injury and lipid deposition, processes often exacerbated by hormonal imbalances, insulin resistance, and systemic inflammation. Reducing this volume is a primary clinical goal in longevity and cardiovascular health management.
