Insights

Simple aortic plaques (SAP) are linked to intracranial atherosclerosis, a stroke risk factor. Detecting SAP during transesophageal echocardiography may indicate advanced vascular disease and aid in stroke prevention strategies.

Area of Science:

  • Cardiovascular Medicine
  • Neurology
  • Vascular Biology

Background:

  • Aortic plaques are associated with cerebrovascular events.
  • Intracranial atherosclerosis is a significant risk factor for stroke.

Purpose of the Study:

  • To investigate the relationship between aortic plaques and intracranial atherosclerosis.
  • To determine if aortic plaque characteristics predict intracranial atherosclerosis.

Main Methods:

  • Retrospective review of 922 stroke patients undergoing transesophageal echocardiography and cerebral angiography.
  • Classification of aortic plaques as simple (SAP) or complex (CAP).
  • Assessment of intracranial (IC) or extracranial (EC) atherosclerosis via angiography.

Main Results:

  • Aortic plaques were found in 26% of patients.
  • Simple aortic plaques (SAP) were significantly associated with intracranial atherosclerosis (OR=1.94).
  • SAP independently predicted IC atherosclerosis in logistic regression analysis.

Conclusions:

  • Simple aortic plaques may serve as a marker for advanced vascular disease.
  • Detection of SAP during echocardiography has clinical implications for identifying patients at risk for stroke due to concomitant intracranial atherosclerosis.

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...

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)...
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Atherosclerosis IV: Nursing Management

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...
