Insights

Increased carotid and brachial artery intima-media thickness (IMT) correlate with diffuse coronary artery disease. These measurements may help predict the extent of atherosclerosis, offering insights into prognostic value.

Area of Science:

  • Cardiovascular Medicine
  • Medical Imaging
  • Atherosclerosis Research

Background:

  • Intima-media thickness (IMT) is a marker of subclinical atherosclerosis.
  • Carotid intima-media thickness (cIMT) and brachial artery IMT (bIMT) are established measures.
  • The relationship between IMT and diffuse coronary artery disease requires further clarification.

Purpose of the Study:

  • To investigate the association between increased cIMT and bIMT and diffuse coronary artery involvement.
  • To compare IMT in patients with diffuse versus focal coronary lesions.
  • To assess the correlation of IMT with overall atherosclerotic burden and lesion length.

Main Methods:

  • Eighty-eight patients with significant coronary artery lesions (≥50%) were analyzed.
  • A novel score was developed to quantify diffuse coronary involvement based on lesion length and narrowing.
  • Measurements of cIMT and bIMT were obtained and compared between patient groups.

Main Results:

  • Both cIMT and bIMT were significantly higher in patients with long coronary lesions compared to those with focal lesions (P < .001).
  • Patients with long coronary lesions exhibited a higher rate of total coronary involvement (P < .001).
  • cIMT showed a stronger correlation with total coronary atherosclerotic burden (r = .495, P < .001) and longest lesion length (r = .489, P < .001) than cardiovascular risk factors.

Conclusions:

  • Increased cIMT and bIMT are associated with diffuse coronary artery disease.
  • IMT measurements demonstrate prognostic value in assessing atherosclerotic burden.
  • These findings may enhance the understanding of IMT's role in predicting cardiovascular outcomes.

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...

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...

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...

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
