Objective radiographic evaluation of cardiac size in clinically normal Zaraibi goats

Abstract

Radiographic evaluation plays a crucial role in the prediction and diagnosis of cardiac disease. Vertebral heart score (VHS) and cardiothoracic ratio (CTR) provide an objective measure to evaluate cardiac size. The aim of the present study was to establish the normal reference values of VHS and CTR in 25 clinically normal Zaraibi goats with homogenous age and body weight. Complete clinical, electrocardiographic, echocardiographic and radiographic examinations were included. The VHS and CTR were calculated from right lateral inspiratory radiographs. The VHS ranged from 7.3 to 8.8 (mean ± SD 8.0 ± 0.4) vertebrae and the CTR ranged from 17.1 to 24.6 (mean ± SD 20.1 ± 2.2) %. Significant weak correlation was recorded between VHS and CTR. Vertebral heart score and cardiothoracic ratio are clinically useful tool to evaluate cardiac size in Zaraibi goats.

“…The main purpose of CTR measurement in humans is to compare the abnormalities of the left ventricle and systolic dysfunction (29). Studies reporting many types of CTR measurements have previously been published (1,5,26). However, as in the VHS, there is no study in which CTR measurements were made in Wistar rats in the literature review.…”

“…Goats are cheaper to maintain, have few housing and management demands, adapting different agro-climatic conditions and can be raised in landless agricultural laborers. Additionally, it is an excellent animal for physiological, biomedical and translational research (Martini et al 2001;Kelly et al 2007;Turner 2007;Raske et al 2010;Abdelgalil et al 2023).…”
