Insights

Patients with primary antiphospholipid syndrome (APS) show impaired endothelial function and increased atherosclerosis markers. These findings suggest endothelial damage and support considering vasoprotective therapies for APS.

Area of Science:

  • Cardiovascular Medicine
  • Immunology
  • Rheumatology

Background:

  • Primary antiphospholipid syndrome (APS) involves thrombotic events and pregnancy complications, linked to antiphospholipid antibodies.
  • Antiphospholipid antibodies can activate endothelial cells and are associated with atherosclerosis.
  • Endothelial dysfunction and early atherosclerosis are potential complications in primary APS.

Purpose of the Study:

  • To assess endothelial impairment in primary APS patients.
  • To evaluate early signs of atherosclerosis in primary APS.
  • To compare vasodilation, von Willebrand factor, and carotid artery intima-media thickness (IMT) between primary APS patients and healthy controls.

Main Methods:

  • Measured flow-mediated (endothelium-dependent) and nitrate-mediated (endothelium-independent) vasodilation.
  • Assessed von Willebrand factor antigen levels.
  • Determined carotid artery intima-media thickness (IMT).

Main Results:

  • Significantly lower flow-mediated vasodilation in primary APS patients compared to controls (3.43% vs. 7.96%).
  • Significantly higher von Willebrand factor antigen levels in primary APS patients (157.91% vs. 125.87%).
  • Significantly larger carotid artery IMT in primary APS patients (0.714 mm vs. 0.58 mm).

Conclusions:

  • Primary APS is associated with ongoing endothelial damage.
  • Patients with primary APS exhibit accelerated atherosclerosis.
  • Vasoprotective therapy may benefit patients with primary APS.

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 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...
Atherosclerosis I: Introduction01:30

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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of 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...

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)...
