This study measured normal ventricular wall thickness in one-year-old dogs, establishing reference values. Ventricular wall thickness correlated with heart weight but not significantly with body weight or blood pressure.

Area of Science:

  • Veterinary Cardiology
  • Comparative Anatomy

Background:

  • Establishing normal physiological parameters is crucial for diagnosing cardiac conditions.
  • Ventricular wall thickness is a key indicator of cardiac health and function.

Purpose of the Study:

  • To determine the normal ventricular wall thickness in one-year-old mongrel dogs.
  • To investigate the correlation between ventricular wall thickness, body weight, heart weight, and arterial blood pressure.

Main Methods:

  • Direct measurement of ventricular wall thickness in 50 mongrel dogs (one year old).
  • Selection of 34 dogs within a specific weight range (8-12 kg) for calculating mean values.
  • Statistical analysis to assess correlations between ventricular thickness and physiological parameters.

Main Results:

  • Provided mean and standard deviation values for left and right ventricular wall thickness at various sites.
  • Found significant correlation between ventricular wall thickness and heart weight.
  • Observed minimal correlation with body weight and no significant correlation with arterial blood pressure.

Conclusions:

  • Established reference values for ventricular wall thickness in one-year-old dogs.
  • Highlighted the stronger relationship between ventricular thickness and heart weight compared to body weight.
  • Indicated the need for further research on aging effects and criteria for ventricular hypertrophy.
