“…However, there are few studies on wild animals using VHS as a diagnostic tool. Felkai et al (2014) described the presence of residual pleural effusion, heart increase and cardiomegaly, associated to increases in the VHS values in Cercopithecus neglectus, confirmed later by echocardiographic examination. The VHS values found in our assessments (mean 9.25±0.32v, between males and females) were similar to those assessed for the Callithrix jacchus (9.42±0.44v), described by Wagner & Kirberger (2005).…”

“…These reference data are scarce for nonhuman primates. Only Felkai et al (2014) describe a CTR of 0.68 (68%) for Cercopithecus neglectus with an acquired heart disease associated to 7-10% fractional shortening. In our studies, we observed strong interaction between the VHS and CTR values (y = 0.1069x -0.4346. r=0.78), a relationship that has not yet been discussed in the literature for nonhuman primates.…”

RESUMO.-[Índice cardiotorácico e vertebral heart size (VHS) para a padronização do tamanho cardíaco do macaco-prego (Cebus apella Linnaeus, 1758) em imagens radiográficas computadorizadas.] Para a avaliação do VHS e ICT foram utilizadas radiografias toráci-cas computadorizadas de 10 macacos-prego (05 machos e 05 fêmeas) clinicamente saudáveis, oriundos do Centro de Triagem de Animais Silvestres de São Luís-MA-CETAS. Foram tomadas radiografias em projeções laterolaterais e dorsoventrais, para cálculo do Vertebral Heart Scale (VHS) e Índice Cardiotorácico (ICT). O VHS evidenciou valores médios de 9,34±0,32v (machos) e 9,16±0,34v (fê-meas), não ocorrendo diferença estatística entre machos e fêmeas (p>0,05). O ICT evidenciou valores médios de 0,55±0,04 (machos) e de 0,52±0,03 (fêmeas), não sendo verificada diferença estatística entre sexos (p>0,05). Verificou-se correlação positiva entre VHS e ICT (r=0,78). Os diâmetros torácico e cardíaco demonstraram valores médios de 5,70±0,48cm e 3,16±0,40cm nos machos, The VHS and CTR were assessed using computerized thoracic radiographs of ten clinically healthy tufted capuchin monkeys (five males and five females) from the Wild Animal Screening Center in São Luís (Centro de Triagem de Animais Silvestres de São Luís-MA--CETAS). Radiographs were taken in laterolateral and dorsoventral projections to calculate the cardiothoracic ratio (VHS) and vertebral heart size (CTR). The VHS showed mean values of 9.34±0.32v (males) and 9.16±0.34v (females) and there was no statistical difference between males and females (p>0.05). The CTR showed mean values of 0.55±0.04 (males) and 0.52±0.03 (females) and there was no statistical difference between the sexes (p>0.05). There was positive correlation between VHS and CTR (r=0.78). The thoracic and heart diameters showed mean values of 5.70±0.48cm and 2.16±0.40cm in the males, respectively. In the females they measured 5.32±0.39cm and 2.94±0.32cm. There was no statistical difference between the sexes. Our results show that the high correlation found between VHS and CTR permitted the verification with similar clinical precision between the two methods to estimate alterations in the heart silhouette by radiographic examination of tufted capuchin, making it an easy technique to apply that can be considered in the investigation of heart problems for this wild species.

“…Published data dealing with CTR measurements in non-human primates are rather scarce. The species Cercopithecus neglectus has been reported to have a CTR value of 0.68; however, these have recorded the incidence of heart disease (13) . When the CTR data found in HNP are compared with that of humans, it is evident that values higher than 0.55 are already accepted to be indicative of cardiomegaly (14) .…”

Heart Measurements of Non-Human Primates by Radiographic Techniques

Thoracic Radiology is a diagnostic technique used to study several aberrations, including cardiac abnormalities, which can be determined by VHS (vertebral heart size). The heart length and width are measured, and the CTR (cardiothoracic ratio) is calculated, by comparing the heart width to the thoracic diameter. This study aimed at measuring the cardiac silhouette of non-human primates (PNH) belonging to the genus Sapajus sp., and the Alouatta guariba species through VHS and CTR. From among the eight animals assessed, it was evident that in both the Sapajus sp. and the Alouatta guariba, the highest HSV change index was observed, depending upon the age of the animal. However, although the individuals of the Alouatta guariba species are bigger in size and heavier, the animals of the genus Sapajus sp. have a larger heart size in proportion to their body. ResumoO uso da radiologia torácica surge como forma de diagnóstico para inúmeras anormalidades, inclusive cardíacas, as quais podem ser avaliadas por métodos VHS (vertebral heart size), realizado a partir da mensuração do comprimento e largura do coração e CTR (cardiothoracic ratio), o qual compara a largura do coração, pelo diâmetro torácico. Assim, objetivamos mensurar a silhueta cardíaca de primatas não humanos (PNH) do gênero Sapajus sp. e espécie Alouatta guariba por meio do VHS e CTR. Dos oito animais avaliados, percebeu-se que tanto nos Sapajus sp. e nos Alouatta guariba, o índice de maior alteração do VHS foi encontrado pela idade do animal. E que apesar dos animais da espécie Alouatta guariba serem maiores e mais pesados, proporcionalmente ao corpo, os animais do gênero Sapajus
