In dogs with heart failure, cell oxygenation and cellular metabolism do not work properly, leading to the production of a large amount of free radicals. In the organism, these free radicals are responsible of major cellular damages: this is oxidative stress. However, a suitable food intake plays an important role in limiting this phenomenon: on the one hand, the presence of essential fatty acids in the composition of membranes decreases sensitivity of cells to free radicals and constitutes a first protection against the oxidative stress; on the other hand, coenzyme Q10, vitamin E, and polyphenols are antioxidant molecules which can help cells to neutralize these free radicals.
在患有心力衰竭的犬类中，细胞氧合作用和细胞代谢无法正常进行，导致大量自由基的产生。在生物体中，这些自由基会造成严重的细胞损伤：这就是氧化应激。然而，适当的食物摄入在限制这种现象方面起着重要作用：一方面，细胞膜成分中必需脂肪酸的存在会降低细胞对自由基的敏感性，并构成对抗氧化应激的第一道防线；另一方面，辅酶Q10、维生素E和多酚都是抗氧化分子，它们可以帮助细胞中和这些自由基。
