Summary

This study reveals that tongue color indicates cardiac function. Purplish tongues correlate with poorer cardiac performance, while pale-red tongues suggest healthier heart function in patients.

Area of Science:

  • Cardiology
  • Traditional Chinese Medicine (TCM)
  • Biomedical Engineering

Context:

  • Tongue diagnosis is a key element in Traditional Chinese Medicine.
  • Cardiac function assessment traditionally relies on electrocardiograms and echocardiograms.
  • Integrating TCM tongue diagnosis with objective physiological measurements offers a novel approach to cardiovascular health assessment.

Purpose:

  • To investigate the correlation between tongue appearance and objective cardiovascular function parameters.
  • To evaluate cardiac diastolic and systolic function, arterial compatibility, and total arterial resistance in relation to tongue color.
  • To establish a potential diagnostic indicator for cardiac health based on tongue presentation.

Summary:

  • A study involving 116 patients examined cardiac function using impedance cardiography, carotid arteriography, and electrocardiography, correlating findings with five tongue color classifications.

  • Results indicated that the pre-ejection period (PEP) was higher in the purplish tongue group, with lower PEP/LVET, heart index (HI), stroke volume (SV), stroke volume index (SVI), and cardiac index (CI).
  • Cardiac function indices were ranked: pale red tongue > red tongue > dark-red tongue > pale tongue > purplish tongue, suggesting a gradient of cardiovascular health associated with tongue color.

    • Impact:

    • Provides objective evidence supporting the use of tongue color as a non-invasive indicator of cardiovascular health.
    • Offers potential for early detection and risk stratification of cardiac dysfunction through simple visual tongue assessment.
    • Highlights the value of integrating traditional diagnostic methods with modern biomedical technology for comprehensive patient evaluation.
