Main Methods:

  • Review of foundational concepts in biomechanics, specifically stress and strain.
  • Description of established and emerging techniques for measuring vascular stiffness.
  • Analysis of mechanical factors contributing to vascular pathologies.

Main Results:

  • Clear definitions of key terms in vascular mechanics are provided.
  • The relationship between stress, strain, and vascular function is detailed.
  • Methods for quantifying vessel wall stiffness are presented.

Conclusions:

  • A solid grasp of vascular mechanics is essential for clinical cardiology.
  • Accurate measurement of vessel stiffness aids in risk assessment.
  • Understanding mechanical principles can guide the prevention and treatment of vascular catastrophes.
