Insights

Polyvascular atherosclerosis, affecting multiple vascular beds, is often underdiagnosed. Combined coronary, carotid, and cerebral computed tomography angiography (CCC CTA) with lipid profiling aids in early detection of this widespread disease.

Area of Science:

  • Cardiovascular Medicine
  • Radiology
  • Preventive Cardiology

Background:

  • Atherosclerosis commonly affects multiple vascular territories simultaneously, contributing to multimorbidity and adverse outcomes in aging populations.
  • Current guidelines lack specific recommendations for detecting polyvascular disease, leading to underdiagnosis.
  • Early, noninvasive screening is crucial for identifying widespread atherosclerosis.

Purpose of the Study:

  • To evaluate the utility of combined coronary, carotid, and cerebral computed tomography angiography (CCC CTA) with lipid profiling for detecting polyvascular atherosclerosis.
  • To assess the prevalence of atherosclerosis in coronary, extracranial carotid, and intracranial arteries.
  • To explore the relationship between polyvascular disease and lipid profiles.

Main Methods:

  • Subset analysis of a prospective registry (BHC-C, NCT05961748) including 719 Chinese patients.
  • Patients underwent one-stop CCC CTA and comprehensive lipid profiling.
  • Analysis included plaque prevalence, stenosis severity, and associations with lipid levels.

Main Results:

  • Coronary atherosclerosis was most prevalent (80.7%), followed by extracranial carotid (77.9%) and intracranial (63.1%) plaques.
  • Moderate-to-severe stenosis (≥50%) was found in 43.1% of coronary, 27.0% of extracranial carotid, and 26.6% of intracranial arteries.
  • Notably, 8.7% of patients had concurrent involvement of all three vascular beds; these patients paradoxically showed lower LDL-C and Lp-PLA2 levels.

Conclusions:

  • CCC CTA combined with lipid panel evaluation can help identify occult polyvascular atherosclerosis.
  • This integrated approach allows comprehensive visualization of multi-bed plaques and risk factor assessment.
  • The findings suggest potential for improved early detection and holistic management of polyvascular disease in primary and secondary prevention.

Blood Studies for Cardiovascular System III: Serum Lipid Profile

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

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)...

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...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
