The investigators' hypothesis is that Jack Russell Terriers (JRTs), Miniature Pinschers (MPs), and Brussels Griffons (BGs) without underlying cardiac disease have breed-specific vertebral heart size (VHS) reference intervals.
The electronic medical records of IDEXX Telemedicine Consultants were searched for JRTs, MPs, and BGs undergoing radiography from January 1, 2023, through June 30, 2023. The study range was expanded to January 1 2022, through June 30, 2023, for BGs only to improve case volume. Dogs were included if they had 2- or 3-view thoracic radiographs performed and no evidence of cardiopulmonary or systemic disease. The VHS and vertebral left atrial size (VLAS) measurements were performed by the same board-certified cardiologist for all images.
During the study period, a total of 991 JRTs, 750 MPs, and 399 BGs were identified. Of these, 689 JRTs, 512 MPs, and 267 BGs were excluded, leaving 302 JRTs, 238 MPs, and 132 BGs available for analysis. The reference intervals for JRTs were 9.7v to 11.8v for VHS and 1.8v to 2.6v for VLAS. The reference intervals for MPs were 9.6v to 12.2v for VHS and 1.7v to 2.4v for VLAS. The reference intervals for BGs were 9.3v to 11.9v for VHS and 1.7v to 2.4v for VLAS.
Jack Russell Terriers, MPs, and BGs have breed-specific VHS and VLAS reference intervals.
Clinicians should be aware of these results to accurately diagnose cardiac disease in these 3 breeds.
研究者的假设是，无潜在心脏病的杰克罗素梗犬（JRTs）、迷你杜宾犬（MPs）和布鲁塞尔格里芬犬（BGs）具有特定品种的脊椎心脏大小（VHS）参考区间。
检索IDEXX远程医疗顾问公司2023年1月1日至2023年6月30日期间接受X线摄影的JRTs、MPs和BGs的电子病历。仅将BGs的研究范围扩大至2022年1月1日至2023年6月30日，以增加病例数量。纳入的犬只需进行了2视图或3视图胸部X线摄影且无心肺或全身性疾病证据。所有图像的VHS和脊椎左心房大小（VLAS）测量均由同一位获得委员会认证的心脏病专家进行。
在研究期间，共识别出991只JRTs、750只MPs和399只BGs。其中，689只JRTs、512只MPs和267只BGs被排除，剩余302只JRTs、238只MPs和132只BGs可供分析。JRTs的VHS参考区间为9.7v至11.8v，VLAS参考区间为1.8v至2.6v。MPs的VHS参考区间为9.6v至12.2v，VLAS参考区间为1.7v至2.4v。BGs的VHS参考区间为9.3v至11.9v，VLAS参考区间为1.7v至2.4v。
杰克罗素梗犬、MPs和BGs具有特定品种的VHS和VLAS参考区间。
临床医生应了解这些结果，以便准确诊断这3个品种的心脏病。
