Insights

Peak plaque structural stress (PSS) predicts cardiovascular events by assessing plaque vulnerability. This biomarker offers improved risk stratification for patients with atherosclerosis, guiding better treatment decisions.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Atherosclerosis is a leading cause of global mortality, primarily driven by coronary plaque rupture or erosion.
  • Current imaging techniques have limitations in accurately predicting major adverse cardiovascular events (MACE) at the individual plaque level.
  • Improved biomarkers are crucial for enhancing risk stratification in patients with coronary artery disease.

Purpose of the Study:

  • To review the methods for calculating plaque structural stress (PSS).
  • To explore the determinants of PSS and its correlation with cardiovascular events.
  • To discuss the potential of PSS as a prognostic tool in coronary artery disease.

Main Methods:

  • Review of existing literature on PSS calculation and validation.
  • Analysis of imaging modalities used for PSS modeling.
  • Examination of experimental and clinical data linking PSS to disease progression.

Main Results:

  • Peak PSS correlates with acute coronary syndrome presentation, plaque rupture, and MACE.
  • PSS integrates plaque architecture, material properties, and hemodynamics for comprehensive risk assessment.
  • PSS provides prognostic information beyond traditional imaging methods.

Conclusions:

  • PSS is a promising biomarker for improving risk stratification in atherosclerosis.
  • Understanding PSS can refine treatment strategies and enhance prediction of future cardiovascular events.
  • Further research into PSS modeling and clinical application is warranted.

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
