Abstract

Little is known about the echocardiographic measurements in the Philippine native horse. To establish baseline references for echocardiographic measurements and values for the Philippine native horses, 29 apparently healthy animals, aged one month to 10 years old with body weights ranging from 19.9-344.7 kg were used in the study. The horses were distributed by sex (15 males and 14 females) and by age (< 1 year old - 6 animals, 1-3 years old - 11 animals, and > 3 years old - 12 animals). Using a 3.5 MHz convex scanner, BM-modes of the heart were obtained through right parasternal short axis views at the level of the ventricles, atria and aorta. Echocardiographic parameters were subjected to Student t-test or one-way ANOVA and correlation analysis. Fractional shortening and ejection fraction were observed to be higher in female than in male Philippine native horses. Differences were also observed in several parameters between age groups. High correlations were found between most echocardiographic parameters and body weights in both male and female Philippine native horses. Most echocardiographic parameters in Philippine native horses were affected by age and body weight, indicating that growth and size of the horse were important factors to take into consideration when performing echocardiography.
