Insights

Traditional Chinese Medicine (TCM) pulse analysis reveals associations between radial artery pulse wave variables and cardiovascular changes in hypertension. These findings support TCM pulse diagnosis for assessing arterial stiffness and heart conditions.

Area of Science:

  • Cardiovascular Physiology
  • Traditional Chinese Medicine (TCM)
  • Biomedical Engineering

Background:

  • TCM pulse diagnosis is a traditional method for assessing health.
  • Hypertension leads to arterial stiffness and cardiac target-organ damage.
  • Understanding the pathophysiological mechanisms linking TCM pulse to cardiovascular changes is crucial.

Purpose of the Study:

  • To explore the cardiovascular pathophysiological mechanisms of TCM pulse.
  • To detect correlations between radial artery pulse wave variables and pulse wave velocity/echocardiographic parameters.
  • To investigate these associations in healthy individuals, hypertensive patients, and those with hypertensive heart disease.

Main Methods:

  • Recruited 200 Chinese subjects across three groups: healthy control, hypertension, and hypertensive heart disease.
  • Collected TCM pulse images (Guan position, left hand), pulse wave velocity, and echocardiographic data.
  • Utilized linear and stepwise regression analysis to assess associations, adjusting for confounding factors.

Main Results:

  • Decreased t1, t5 and increased h1, h3/h1 pulse wave variables correlated with arterial stiffness in the total population.
  • Decreased t3 and h5 correlated with arterial stiffness within specific groups.
  • The dicrotic wave height (h5) was the most relevant variable, showing associations with interventricular septal thickness, posterior wall thickness, ejection fraction, and ventricular diameters.

Conclusions:

  • Radial artery pulse wave variables are associated with arterial stiffness and echocardiographic changes in hypertension.
  • These findings provide an experimental basis for understanding the cardiovascular pathophysiological mechanisms of TCM pulse variables.
  • TCM pulse analysis offers a potential non-invasive method for cardiovascular risk assessment.

Assessment of radial pulse

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Wave Parameters

The simplest mechanical waves are associated with simple harmonic motion and repeat themselves for several cycles. These simple harmonic waves can be modeled using a combination of sine and cosine functions. Consider a simplified surface water wave that moves across the water's surface. Unlike complex ocean waves, in surface water waves, water moves vertically, oscillating up and down, whereas the disturbance of the wave moves horizontally through the medium. If a seagull is floating on the...

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Velocity and Acceleration of a Wave00:51

Velocity and Acceleration of a Wave

A wave propagates through a medium with a constant speed, known as a wave velocity. It is different from the speed of the particles of the medium, which is not constant. In addition, the velocity of the medium is perpendicular to the velocity of the wave. The variable speed of the particles of the medium implies that there must be acceleration associated with it. 
The velocity of the particles can be obtained by taking the partial derivative of the position equation with respect to time....

Pulse01:16

Pulse

When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...

Pulse

The pulse is one of the most fundamental physiological indicators of the body's cardiovascular health. It is the rhythmic expansion and contraction of the arterial walls in response to the pressure generated by the heart's pumping action.
Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...
