Insights

Measuring carotid plaque burden, including total plaque area (TPA) and total plaque volume (TPV), offers superior risk stratification and atherosclerosis research capabilities compared to intima-media thickness (IMT). Vessel wall volume (VWV) is a viable alternative for those without plaque.

Area of Science:

  • Cardiovascular Imaging
  • Atherosclerosis Research
  • Vascular Biology

Background:

  • Carotid plaque burden measurement, including total plaque area (TPA) and total plaque volume (TPV), is crucial for understanding atherosclerosis.
  • Current methods like carotid intima-media thickness (IMT) have limitations in comprehensively assessing plaque burden.

Purpose of the Study:

  • To delineate the applications of measuring carotid plaque burden using TPA, TPV, and vessel wall volume (VWV).
  • To highlight the advantages of plaque burden measurement over IMT in clinical practice and research.

Main Methods:

  • Review of current literature and clinical applications of carotid plaque burden quantification.
  • Comparison of plaque burden metrics (TPA, TPV, VWV) with carotid intima-media thickness (IMT).

Main Results:

  • Plaque burden measurement is vital for atherosclerosis risk stratification and patient management.
  • It facilitates research into atherosclerosis genetics, biology, and the efficacy of novel therapies.
  • Vessel wall volume (VWV) serves as an effective alternative to IMT for individuals without detectable plaque.

Conclusions:

  • Measurement of carotid plaque burden (TPA, TPV, VWV) is a superior method for atherosclerosis assessment compared to IMT.
  • These advanced imaging techniques should be integrated into clinical practice and research for improved patient outcomes.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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)...

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...
