Abstract：
OBJECTIVE: The inclusion of vertebral heart score (VHS) and, more recently, the inclusion of the vertebral left atrial size (VLAS) in radiographic evaluation have become important screening tools for identifying dogs with occult cardiac disease. Several recent papers have shown there are interbreed variations in the VHS reference range. Our hypothesis is that the Miniature Schnauzer would also have a higher reference range for its VHS.
METHODS: The electronic medical records of IDEXX Telemedicine Consultants were searched for Miniature Schnauzers undergoing thoracic radiographs between March 1, 2022, and February 28, 2023.
METHODS: Dogs were included if they had 3 view thoracic radiographs performed and no evidence of cardiopulmonary disease was detected. Dogs with incomplete radiographic studies or cardiac or extracardiac disease were excluded. The VHS and VLAS measurements were performed by 2 board-certified cardiologists independent of one another.
RESULTS: A total of 1,000 radiographs were obtained of which 272 were included for the study. The overall range for the VHS in this cohort was 9.68 to 12.07 with a median of 10.9. For VLAS measurements, a range of 1.71 to 2.4 was documented with a median of 2.0.
CONCLUSIONS: The VHS for Miniature Schnauzers without cardiac disease was confirmed to be higher than the canine reference range.

摘要：
目的：纳入椎体心脏评分（VHS）和，最近,在影像学评估中纳入椎体左心房大小(VLAS)已成为识别隐匿性心脏病犬的重要筛查工具.最近的几篇论文表明，VHS参考范围存在品种间的差异。我们的假设是，微型雪纳瑞的VHS参考范围也将更高。
方法：在2022年3月1日至2023年2月28日期间，对IDEXX远程医疗顾问的电子病历进行了搜索，以寻找接受胸部X光检查的小型雪纳犬。
方法：如果狗进行了3次胸片检查，并且没有检测到心肺疾病的证据，则将它们包括在内。排除放射学研究不完整或心脏或心外疾病的狗。VHS和VLAS测量由2位相互独立的认证心脏病专家进行。
结果：共获得1,000张X射线照片，其中272张被纳入研究。该队列中VHS的总体范围为9.68至12.07，中位数为10.9。对于VLAS测量，记录的范围为1.71~2.4,中位数为2.0.
结论：经证实，无心脏疾病的小型雪纳犬的VHS高于犬的参考范围。
