Key result
Doppler echocardiographic measurements of diastolic function in healthy dogs were significantly influenced by body weight, heart rate, and age, with body weight affecting the largest number of parameters.
Why the study?
The study was conducted to obtain reference values for diastolic cardiac function parameters in healthy dogs and evaluate differences across age, weight, and sex.
How do age, gender, and weight influence transthoracic echocardiographic evaluation of diastolic parameters in healthy dogs?
Cross-Sectional (n=82)

How do age, gender, and weight influence transthoracic echocardiographic evaluation of diastolic parameters in healthy dogs?
Body weight, heart rate, and age significantly influence non-invasive echocardiographic diastolic parameters in healthy dogs, providing reference ranges for veterinary cardiology.
Body weight, heart rate, and age should be considered when interpreting canine diastolic parameters; extends reference data but leaves diagnostic thresholds open.
The aim of this study was to obtain reference values for diastolic cardiac function parameters in healthy dogs and to ascertain if significant differences exist between dogs of various age, weight and sex. The study was performed on 82 healthy dogs of different age and breed. Eleven param- eters were analyzed: peak velocity during early diastolic filling, acceleration time of early diastol- ic filling, deceleration time of early diastolic filling, total time of early diastolic filling, peak veloc- ity during late diastolic filling, acceleration time of late diastolic filling, deceleration time of late diastolic filling, total time of late diastolic filling, total time of early and late diastolic filling, ratio of peak velocities during early and late diastolic filling, isovolumetric relaxation time. The Dop- pler measurements used for general assessment of diastolic function in healthy dogs were signifi- cantly influenced by body weight, heart rate and age. No significant differences were found be- tween males and females. This study described the value of non-invasive echocardiographic assessment of diastolic function in healthy dogs.

Garncarz et al. (2018) conducted a cross-sectional in Healthy dogs (n=82). Age, body weight, and heart rate was evaluated on Echocardiographic measurements of transmitral and left ventricular outflow tract diastolic function. Doppler echocardiographic measurements of diastolic function in healthy dogs were significantly influenced by body weight, heart rate, and age, with body weight affecting the largest number of parameters.
