Leg pulse wave analysis offers a new numerical method to assess arterial system health. Higher pulse wave values may indicate better circulation and potentially increased longevity.

Area of Science:

  • Biomedical Engineering
  • Cardiovascular Physiology
  • Medical Diagnostics

Background:

  • Arterial system deterioration is evident but difficult to quantify.
  • Leg pulse waves, measured via electric impedance plethysmography, show potential for assessing circulatory health.
  • Previous work analyzed pulse waves using Fourier analysis and a lumped component model.

Purpose of the Study:

  • To determine if numerical values can be assigned to different types of leg pulse waves.
  • To establish a new tool for analyzing peripheral circulation and atherosclerosis.
  • To provide a method for evaluating therapies affecting the circulatory system.

Main Methods:

  • Mathematical analysis of leg pulse wave data from a previous study.
  • Advanced computer analysis of pulse wave characteristics, including sine amplitude and notch depth.

  • Data from a cohort of generally healthy white males across various age groups (5-91 years).

    • Main Results:

    • Sine amplitude versus age showed a trend intersecting age 100.
    • Pulse wave notch depth versus age also indicated an intersection around age 100.
    • Mathematical and graphic methods confirmed that pulse waves can be numerically quantified, with higher numbers suggesting better circulation.

    Conclusions:

    • The study suggests a potential functional lifespan limit for the untreated circulatory system around age 100.
    • Quantifiable pulse wave analysis can serve as a tool for assessing peripheral circulation.
    • Improving pulse wave numerical values through treatment may enhance circulatory system longevity.
