摘 要
猫肥胖症作为一种全球性健康问题，近年来发病率显著上升，尤其在城市宠物猫中更为普遍。肥胖不仅影响猫的代谢功能，还对心血管系统产生深远影响。本研究旨在通过长期观察，探讨肥胖对猫心血管系统的具体影响及其潜在机制。研究选取了100只不同体重的猫作为样本，进行了为期五年的跟踪调查，采用定期体检、血液生化分析及超声心动图等方法，评估其心脏功能和血管健康状况。结果显示，肥胖猫的心脏肥大、血压升高及动脉硬化发生率显著高于正常体重猫，且这些变化与体重指数呈正相关。此外，肥胖猫的血浆脂质代谢异常，尤其是甘油三酯和低密度脂蛋白胆固醇水平显著升高，进一步加剧了心血管疾病的风险。

LONG-TERM OBSERVATION OF THE EFFECTS OF OBESITY ON CARDIOVASCULAR SYSTEM IN CATS
ABSTRACT
Cat obesity, a global health problem, has increased significantly in recent years, especially among urban pet cats. Obesity not only affects the me tabolic function of cats, but also has a profound impact on the cardiovascular system. The aim of this study was to investigate the specific effects of obesity on cat cardiovascular system and its potential mechanisms through long-term observation. A total of 100 cats with different body weights were followed for five years to assess their heart function and vascular health using regular physical examinations, blood biochemical analysis and echocardiography. The results showed that the incidence of heart hypertrophy, elevated blood pressure and arteriosclerosis in obese cats was significantly higher than that in normal weight cats, and these changes were positively correlated with body mass index. In addition, obese cats have abnormal plasma lipid me tabolism, especially significantly elevated levels of triglycerides and low-density lipoprotein cholesterol, further exacerbating the risk of cardiovascular disease.
