Key result
In healthy small breed dogs, mitral peak A velocity positively correlated with age and mitral E/A ratio positively correlated with body weight, while other Doppler parameters were negatively correlated.
Why the study?
The study aimed to evaluate and correlate age and body weight with pulsed-wave Doppler echocardiographic indices in small breed dogs.
Observational (n=13)
No
This study establishes baseline correlations between age, body weight, and pulsed-wave Doppler echocardiographic indices in healthy small breed dogs to inform future pathophysiological studies.
May guide mitral reference ranges in healthy small dogs; leaves open validation in clinical or other breeds.
The study aims to evaluate and find the correlation of age and body weight of pulse wave Doppler echocardiographic indices of mitral velocity, tricuspid velocity, pulmonary and aortic velocity in 13 apparently healthy small breed dogs aged 1 to 9 years and weighing 6.5 to 15 kg were subjected to pulsed-wave Doppler echocardiography examination. Except for a positive correlation with age by Mitral peak A velocity and a positive correlation with body weight by Mitral E/A ratio, all other parameters are negatively correlated with age and body weight. The findings can be used to further determine the pathophysiological affections in future studies on small breed dogs.

Prabha Sharma (2021) conducted an observational in Healthy small breed dogs (n=13). Age and body weight was evaluated on Correlation of age and body weight with pulse wave Doppler echocardiographic indices. In healthy small breed dogs, mitral peak A velocity positively correlated with age and mitral E/A ratio positively correlated with body weight, while other Doppler parameters were negatively correlated.
