Insights

Preserved endothelial function aids spontaneous healing in cervicocephalic arterial dissections (CCAD). Increased arterial stiffness is linked to ischemic presentation in CCAD patients.

Area of Science:

  • Vascular Biology and Medicine
  • Cardiovascular Research
  • Neurology and Stroke

Background:

  • Spontaneous cervicocephalic arterial dissections (CCAD) are influenced by arterial wall properties.
  • Endothelial function and arterial stiffness are key mechanical and physiological properties.
  • Assessing these properties may elucidate CCAD behavior and outcomes.

Purpose of the Study:

  • To investigate the impact of endothelial function and arterial stiffness on CCAD clinical characteristics and outcomes.
  • To utilize brachial flow-mediated dilation (FMD) and brachial-ankle pulse wave velocity (PWV) as measures.
  • To correlate FMD and PWV findings with CCAD presentation, healing, and recurrence.

Main Methods:

  • Retrospective analysis of 146 CCAD patients from a single-center database (April 2011 - December 2021).
  • Assessment of endothelial function via brachial flow-mediated dilation (FMD) and arterial stiffness via brachial-ankle pulse wave velocity (PWV).
  • Comparative and multivariable analyses to determine associations between FMD/PWV and clinical outcomes.

Main Results:

  • Normal FMD levels were significantly associated with spontaneous dissection healing (adjusted OR: 4.52).
  • The highest PWV tertile was strongly associated with ischemic stroke presentation (adjusted OR: 17.05).
  • While trends suggested higher recurrence and aneurysmal enlargement in specific PWV groups, frequencies were too low for multivariable analysis.

Conclusions:

  • Preserved endothelial function is a positive predictor of spontaneous arterial healing in CCAD.
  • Increased arterial stiffness, as measured by PWV, is significantly associated with an ischemic presentation in CCAD.
  • These vascular properties offer insights into CCAD pathophysiology and patient risk stratification.

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)...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

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 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...
