摘要: 旨在研究不同体尺伊犁马之间心脏结构和功能参数的内在联系,提高运动马选育效率。本研究使用彩色多普勒超声系统测定健康状况良好的30匹2岁伊犁马的心脏结构和功能参数,分析伊犁马体高、体长、胸围、管围等体尺与心脏结构和功能参数的相关性并拟合线性模型。结果表明,伊犁马体重、体表面积、体长、胸围与舒张末期左心房内径(LADd)呈极显著正相关(P<0.01);体重、体表面积、胸围与二尖瓣内径(MVD)、舒张末期肺动脉内径(PAd)呈显著正相关(P<0.05);体长与MVD呈极显著正相关(P<0.01),与收缩末期左心室游离壁厚度(LVFWs)、左心室心肌质量(LVM)呈显著正相关(P<0.05);体高与左心室长轴径(LVLD)呈极显著正相关(P<0.01);管围与收缩末期左心房内径(LADs)、MVD呈显著正相关(P<0.05)。其他各体尺与心脏结构间相关性均不显著(P>0.05)。体重、体表面积、体长、胸围与舒张末期左心室容量(EDV)、收缩末期左心室容量(ESV)呈显著正相关(P<0.05);体表面积、胸围与左心室射血分数(EF)呈显著负相关(P<0.05);体高与EDV、每搏量(SV)呈极显著正相关(P<0.01),与心输出量(CO)呈显著正相关(P<0.05);管围与左心室心肌质量指数(LV MASS-I)呈显著负相关(P<0.05)。共拟合12个线性回归方程,R2值(决定系数)均高于0.9,达到极显著水平,均可用于生产实践中。伊犁马体长与体高对心脏结构和功能参数的影响较大。对不同体尺的伊犁马间的心脏结构和功能参数进行相关性及回归分析,为马匹心脏评估提供理论依据。

Abstract: The study aimed to study the internal relationship between cardiac structure and function parameters of Yili horses with different body sizes and improve the efficiency of sports horse selection. In this study, the cardiac structure and function parameters of 30 healthy 2-year-old Yili horses were measured by color Doppler ultrasound system. The correlation between body height, body length, thoracic circumference, pipe circumference and cardiac structure and function parameters of Yili horses was analyzed and the linear model was fitted. The results showed that the weight, body surface area, body length and thoracic circumference of Yili horses were positively correlated with LADd (P<0.01). Body weight, body surface area, thoracic circumfere-nce were positively correlated with MVD and PAd (P<0.05). Body length was positively correlated with MVD (P<0.01), LVFWs and LVM (P<0.05). Body height was positively correlated with LVLD (P<0.01). Pipe circumference was positively correlated with LADs and MVD (P<0.05). There was no significant correlation between other body size and cardiac structure (P> 0.05). Body weight, body surface area, body length, thoracic circumference were positively correlated with EDV and ESV (P<0.05). Body surface area and thoracic circumference were negatively correlated with EF (P<0.05). Body height was positively correlated with EDV,SV (P<0.01) and CO (P<0.05). Pipe circumference was negatively correlated with LV MASS-I (P<0.05). A total of 12 linear regression equations were fitted, and the R2 values (coefficient of determination) were all higher than 0.9, reaching the extremely significant level, which could be used in production practice. The body length and body height of Yili horses have great influence on the cardiac structure and function parameters. Conducting correlation and regression analysis of cardiac structure and function parameters among Yili horses of different body sizes can provide theoretical basis for cardiac evaluation of horses.
