“…The mean VHS of all groups of dogs in the present study was greater than the upper limit for nor- mal heart size in most canine breeds (VHS ≤ 10.5) [6]. Values of VHS higher than the above upper limit have been reported for boxers (11.6 ± 0.8), cavalier king Charles spaniels (10.6 ± 0.5), Labrador retrievers (10.8 ± 0.6), whippets (11.0 ± 0.5) and greyhounds (10.5 ± 0.1) [4,15,20], but no boxers, cavalier king Charles spaniels, Labrador retrievers, whippets or greyhounds were included in the present study. The mean VHS of our dogs with cardiac or mixed origin of cough was significantly higher compared with the mean VHS of the dogs with a non-cardiac origin of cough.…”

“…The VHS is the vertebral scale sum of the long and short axes, each measured caudally from the cranial edge of the 4th thoracic vertebra. Normal VHS values have been established for cats [16] and ferrets [26] as well as for different canine breeds [4,15,20]. Furthermore, this method is largely employed for radiographic evaluation of the heart in dogs with different cardiovascular disorders.…”

ABSTRACT. The objective of the present study was to evaluate the usefulness of the vertebral heart score (VHS) in coughing dogs with chronic degenerative mitral valve disease (MVD). Survey thoracic radiographs of 90 dogs with a history of cough and clinical and echocardiographic evidence of MVD were evaluated by 2 independent observers. The observers were asked to first determine the origin of the cough as cardiac, non-cardiac or mixed and then to measure the VHS. Agreement regarding diagnosis of the origin of cough was obtained (kappa=0.64) in 69 dogs. Of these 69 dogs, 28 (41%), 32 (46%) and 9 (13%) had a cough of cardiac, non-cardiac and mixed origin, respectively. The dogs with a cough of non-cardiac origin had a significantly lower VHS (mean ± SD, 11 ± 0.9) compared with those of dogs with a cough of cardiac or mixed origin (12.8 ± 1 and 12.9 ± 0.9, respectively). Receiver operating characteristic curve analysis showed that a VHS ≤ 11.4 is fairly accurate for exclusion of a cough of cardiac origin in dogs with MVD. The results indicate that the VHS may be an additional tool for differentiating the origin of cough in dogs with MVD. KEY WORDS: canine and feline, cardiology, echocardiography, heart, radiology.J. Vet. Med. Sci. 71(1): 9-13, 2009The term "cardiac cough" is frequently used in the clinical setting as well as in veterinary textbooks to define the origin of cough in dogs affected by cardiac disorders. Chronic degenerative mitral valve disease (MVD) with associated mitral regurgitation (MR) is the most common canine cardiovascular disease [5] and coughing is the most common presenting complaint in dogs with MVD [10]. This symptom may be related to different pathophysiological mechanisms secondary to cardiac dilatation and dysfunction caused by MVD. Among the main consequences of MVD are dorsal elevation and compression of the trachea and/or dorsal elevation of the left main stem bronchus by the dilated left atrium, pulmonary congestion and pulmonary interstitial and/or alveolar transudate secondary to increased pulmonary capillary pressure [10]. The above mechanisms may be responsible for cough in dogs with MR [2]. Nevertheless, cough can be a consequence of different respiratory disorders that may concurrently affect dogs with MVD [1]. In particular, the same dogs (i.e., small or middle-sized, aged dogs) most commonly affected by MVD are predisposed to some respiratory disorders leading to cough (e.g., chronic bronchitis, lower airway collapse and interstitial lung disease) [12,21,24]. Thus, both respiratory and cardiac diseases may contribute to cough in some cases.The vertebral heart score (VHS) is a method for objectively evaluating the dimensions of the cardiac silhouette in thoracic radiograms and was first described by Buchanan and Bücheler in the dog [7]. Using this method, the cardiac long and short axis are measured on the lateral thoracic view and are then compared with the thoracic spine. The VHS is the vertebral scale sum of the long and short axes, each measured caudally from the crania...

“…Research has demonstrated that Greyhounds have hematologic and biochemical differences from other breeds, some of which are not widely known in the veterinary field. [1][2][3] Greyhounds have physiologic differences including a larger heart size, 4,5 a higher vertebral heart score, 6 high glomerular filtration rate, 7 high arterial blood pressure, 4,5 and relative aortic stenosis. 8 To date, research has focused mainly on the physiologic and clinicopathologic peculiarities of Greyhounds, but there is little published data for disease prevalence in the breed.…”

Background: Adoption of retired racing Greyhounds has become increasingly popular during the past decade. To date, research has focused on the physiologic and clinicopathologic peculiarities of Greyhounds but there is little published information on disease prevalence in the breed.Objective: The objective of this study is to determine the prevalence of disease in retired racing Greyhounds. Animals: In this study, 747 Greyhounds were used. Methods: A standardized survey method was used, and survey responses were collected by an Internet survey. Owners could answer a survey for every Greyhound that they had owned since January 1, 2005.Results: Of the 692 eligible participants, 441 (63.7% response rate) completed surveys for 747 Greyhounds. The mortality rate for Greyhounds within the 2-year period was 15% (113 of 747 died). The most common cause of death reported was cancer (66 dogs, 58%), and the most common type of cancer listed as the cause of death was osteosarcoma (28 dogs, 25%). The most commonly reported groups of diseases or disorders were skeletal (232 dogs, 33%), skin (197 dogs, 28%), digestive (132 dogs, 18%), cancer (94 dogs, 13%), and endocrine (85 dogs, 11.9%). Forty-five percent of Greyhounds diagnosed with cancer and 6% of the overall population had osteosarcoma.Conclusions and Clinical Importance: The results of this study can be used by veterinary researchers to continue to investigate the most common diseases in this population. As more retired racing Greyhounds enter the pet population, the results of this study will help educate veterinarians and owners about the most prevalent diseases in the breed.

ÖZETRadyografik Kardiyomegali, toraks röntgenlerinde kalp siluetinin normal referans değerlerin üstünde olması anlamına gelmektedir. Kardiyomegali tek başına bir hastalık belirtisi olmayıp, altta yatan diğer hastalıklar sonucunda da oluşabilmektedir. Toraks röntgenlerinde rastlanan Radyografik Kardiyomegali bulgusu genelde kalp hastalıkları ile ilişkilendirilmekte, çoğu kez kalp hastalıkları dışındaki durumlar göz ardı edilmektedir. Bu derleme; Radyografik Kardiyomegali'nin saptanmasıyla başlayan tanısal ve klinik yaklaşımları ve teşhise kadar uzanan süreci klinisyen gözüyle değerlendirmektedir.Anahtar Kelimeler: Kardiyomegali, köpek, radyografi, teşhis RADIOGRAPHIC CARDIOMEGALY IN DOGS: FROM RADIOGRAPHY TO CLINICAL APPROACH ABSTRACTRadiographic cardiomegaly means that the heart silhouette is above the normal reference values in thorax radiographs. Cardiomegaly is not a symptom of a disease alone, but it can also occur as a result of other underlying diseases. Although physicians usually rule out secondary disease related to radiographic cardiomegaly, cardiomegaly sign in chest X-rays are usually associated with heart diseases. This review consider the diagnostic and clinical approaches starting with the detection of radiographic cardiomegaly and the process leading up to the diagnosis.
