Endothelial dysfunction, an imbalance in blood vessel tone regulation, is key in early atherosclerosis and hypertension. Monitoring this dysfunction is crucial for assessing subclinical atherosclerosis and predicting disease risk.

Area of Science:

  • Vascular Biology
  • Endothelial Function

Context:

  • The endothelium regulates vascular tone via vasodilating and vasoconstricting mediators.
  • An imbalance in these mediators defines endothelial dysfunction.
  • This dysfunction is implicated in atherosclerosis and hypertension pathogenesis.

Purpose:

  • To explain the role of the endothelium in vascular homeostasis.
  • To define endothelial dysfunction and its pathological significance.
  • To highlight the need for improved diagnostic methods for endothelial dysfunction.

Summary:

  • The endothelium produces substances that control vascular tone, structure, permeability, coagulation, and inflammation.
  • Endothelial dysfunction involves an altered balance of these mediators, leading to reduced endothelium-dependent relaxations.

  • It is a critical early event in atherosclerosis and hypertension.

    • Impact:

    • Current testing for endothelial dysfunction includes vasomotion tests and circulating markers.
    • Further development of diagnostic panels is needed to quantify dysfunction, predict risk, and guide therapy.
    • Accurate assessment of endothelial dysfunction aids in managing cardiovascular diseases.
