Frequent high-intensity exercise entails cardiac remodeling both in humans and animals. In dogs, especially those used for top-level competition, it is of great interest to learn whether they develop the so-called athletic heart syndrome. In order to improve the clinical monitoring on behalf of the veterinarians who tend to these animals, professor at the Faculty of Veterinary Science at the CEU Cardenal Herrera University (CEU UCH) of Valencia, Milagros Benito, has proposed a cardiac assessment protocol based on an electrocardiographic and echocardiographic examination of these dogs before and after a racing effort, seeking an early detection of the cardiac indicators that differentiate athletic heart syndrome from other cardiac diseases.
