“…Changes in LVID and LV mass are considered relevant, as they have strong positive correlations with aerobic capacity and are associated with better performance in thoroughbred horses [1]. The relationship between heart size and race performance was addressed in several studies [1][2][3]5]. Moreover, similar to what was found in racing breeds, higher LVIDd and SV in Arabian horses may lead to improved performance [4].…”

“…Cardiac remodeling in horses can be assessed by echocardiography, a procedure that accurately identifies training-associated changes [1][2][3][4][5]. Long-term intensive training leads to a cardiac adaptation known as "athlete's heart", which comprises two distinct morphologies [6].…”

“…This was explained by the different characteristics of the training program, as well as its intensity, volume, and duration [2,[6][7][8][10][11][12][13]. Additionally, disparities in body size, age, gender, and possibly between breeds make it difficult to extrapolate results and comparisons [2,5,8,[14][15][16].…”

Cardiac adaptation to conditioning in horses was evaluated after empirical training based on trainers’ experience. Twelve purebred Arabian horses, aged (mean ± SD) 28.42 ± 3.75 months, which did not perform any type of exercise prior to the research, were submitted to treadmill conditioning for six weeks. The conditioning program was based on the velocity run by the horse at which the blood lactate concentration, determined in an incremental exercise test (IET), reached 2 mmol/L (V2). The velocity at which the blood lactate concentration reached 4 mmol/L (V4) was also determined. The echocardiograms were performed at rest with pulsed-wave and tissue Doppler imaging in B- and M-modes. All procedures were carried out before and after the conditioning period. The results showed increases in V2 (from 5.2 ± 0.3 to 6.7 ± 0.4 m/s) and V4 (from 5.8 ± 0.4 to 7.6 ± 0.5 m/s) (p < 0.0001). There were also increases in the left ventricle internal diameter at diastole (LVIDd), left ventricle mass (LV mass), and stroke volume (SV), while no changes were observed in the LV free wall thickness and mean and relative wall thicknesses. The conditioning protocol, which was completed by all horses, proved to be safe and efficient, as it improved the aerobic capacity of the animals. Finally, the cardiac remodeling that occurred was mainly associated with the effect of physical training.

“…Namun, bukan jenis kelamin (Al-Haidar et al, 2017). Kuda jantan memiliki hasil pengukuran ventrikel yang lebih besar dibandingkan kuda betina (Fintl et al, 2020). Ketebalan dinding interventricular, atrium kanan, dan kiri lebih besar pada kerbau betina dibandingkan kerbau jantan (Bhasin et al, 2017).…”

Badak sumatera berada di ambang kepunahan akibat perburuan dan kehilangan habitat. Badak sumatera yang keluar dari habitatnya (doomed) dan terisolasi diselamatkan dan ditranslokasi ke Suaka Rhino Sumatera (SRS) Taman Nasional Way Kambas Lampung dalam rangka melindungi dan membiakkan mereka untuk konservasi. Salah satu penyebab kematian badak sumatera dewasa adalah gangguan jantung (kardiomiopati, miokarditis, infark jantung) dan kegagalan kardiovaskuler akibat penyakit paru-paru maupun gastrointestinal. Tujuan dari studi ini adalah menentukan teknik pemeriksaan ekokardiografi transthoraks pada badak sumatera, melihat struktur internal jantung dan mengetahui dimensi ukuran jantung badak sumatera. Ekokardiografi transthoraks dilakukan pada badak sumatera di Suaka Rhino Sumatera menggunakan transduser phased-array dengan frekuensi 3.5 MHz yang diletakkan di sela iga/intercostae parasternal thoraks sisi kiri (left parasternal) dan kanan (right parasternal). Pada pemeriksaan ekokardiografi, seluruh badak sumatera pada posisi berdiri dalam kondisi sadar tanpa anestesi. Gambaran ekokardiografi Brightness-mode pada badak sumatera paling jelas didapatkan dari sudut pandang left parasternal pada intercostae ke-3 dan ke-4 baik gambaran long axis maupun short axis. Gambaran ekokardiografi yang didapatkan dari sudut pandang left parasternallong axis dan right parasternallong axis berupa four chamber (atrium kanan, atrium kiri, ventrikel kanan, ventrikel kiri), sedangkan five chamber (empat ruang jantung dan aorta) didapatkan dari sudut pandang right apical dan left apical. Dimensi jantung berdasarkan pengukuran dengan Motion-mode adalah IVSd 2,12 ± 0,25 cm; LVIDd 9,70 ± 0,82 cm; LVPWd 1,82 ± 0,12 cm; IVSd/LVPWd 1,20 ± 0,21 cm; bobot ventrikel kiri 1723,90 ± 311,45 g; RWT 0,38 ± 0,05; IVSs 2,83 ± 0,30 cm; LVIDs 5,41 ± 0,96 cm; LVPWs 3,28 ± 0,3 cm; EDV 952,69 ± 231,36 mL; ESV 185,38 ± 90,93 mL; SV 767,31 ± 150,92 mL; CO 38769,19 ± 8222,88 mL/menit; EF 81,95 ± 5,55%; FS 41,96 ± 8,24%.
