摘要
本研究旨在通过评估血液中的肉碱含量，对肥厚型心肌病（HCM）早期心肌能量代谢发生变化这一假设进行前瞻性研究。本研究共纳入了 14 只患有 HCM B1 期的客户饲养猫和 22 只临床健康猫。测量了两组猫血清中的总肉碱、游离肉碱、酰基肉碱和酰基肉碱/游离肉碱比率（AF 比率）。两组之间的总肉碱、游离肉碱和酰基肉碱浓度没有明显差异。然而，HCM 组的 AF 比值明显低于对照组（P=0.02）。早期 HCM 猫的血清 AF 比值较低，这可能表明其心肌能量代谢发生了改变。
A pilot study investigating serum carnitine profile of cats with preclinical hypertrophic cardiomyopathy.
This study aimed to prospectively investigate the hypothesis that myocardial energy metabolism changes in the early stages of feline hypertrophic cardiomyopathy (HCM) by evaluating the blood carnitine profiles. Fourteen client owned cats with HCM stage B1 and 22 clinically healthy cats were included in this study. Total-carnitine, free-carnitine, acylcarnitine, and acylcarnitine/free-carnitine ratio (AF ratio) in serum were measured in both groups. No significant differences were observed in total-carnitine, free-carnitine, and acylcarnitine concentrations between the groups. However, the AF ratio in the HCM group was significantly lower than that of the control group (P=0.02). The lower serum AF ratio in cats with early-stage HCM, may suggest an alteration in their myocardial energy metabolism.
期刊介绍：
JVMS is a peer-reviewed journal and publishes a variety of papers on veterinary science from basic research to applied science and clinical research. JVMS is published monthly and consists of twelve issues per year. Papers are from the areas of anatomy, physiology, pharmacology, toxicology, pathology, immunology, microbiology, virology, parasitology, internal medicine, surgery, clinical pathology, theriogenology, avian disease, public health, ethology, and laboratory animal science. Although JVMS has played a role in publishing the scientific achievements of Japanese researchers and clinicians for many years, it now also accepts papers submitted from all over the world.
