INTRODUCTION/OBJECTIVES: The objectives were to conduct a survey of cardiologists on their recent experiences with cats that have dilated cardiomyopathy (DCM) and to retrospectively review individual cases of feline DCM.
ANIMALS, MATERIALS AND METHODS: Part one: A survey was distributed to cardiologists with questions regarding caseload and clinical management of cats with DCM diagnosed over the past two years. Part two: Cardiologists completing the survey were invited to submit data from cats recently diagnosed with DCM. Data on signalment, clinical signs, diet, echocardiographic measurements and outcome were recorded.
Part one: From 52 completed surveys, many cardiologists responded that measuring and supplementing taurine and recommending a diet change in cats with DCM are common practices. Few (15%) cardiologists reported an increase in the number of feline DCM cases over the past two years, although some had cases that improved even if taurine deficiency was not present. Part two: Twenty of 37 (54%) cats ate low pea/lentil (low PL) diets, and 14/37 (38%) ate high PL diets at the time of diagnosis; three had incomplete diet information. Two of 13 cats (15%) in which taurine was measured had levels below the reference range. After adjusting for other variables, cats eating high PL diets that changed diets after diagnosis had a significantly longer survival time than that of cats eating high PL diets that did not change diets after diagnosis (P = 0.025).
Additional research is warranted to determine whether there could be a possible association between diet and DCM in cats.
简介/目的：目的是对心脏病专家进行一项关于他们最近接触患有扩张型心肌病（DCM）的猫的经验的调查，并回顾个别猫 DCM 病例。
动物、材料和方法：第一部分：向心脏病专家分发了一份调查问卷，内容涉及过去两年中诊断出患有 DCM 的猫的病例量和临床管理。第二部分：完成调查的心脏病专家受邀提交最近诊断出患有 DCM 的猫的数据。记录了一般信息、临床症状、饮食、超声心动图测量值和结果。
第一部分：在 52 份完成的调查中，许多心脏病专家表示，测量和补充牛磺酸以及建议改变患有 DCM 的猫的饮食是常见做法。尽管有些猫的牛磺酸缺乏症没有得到纠正，但病情却有所改善，但只有 15%的心脏病专家报告过去两年中猫 DCM 病例有所增加。第二部分：20/37（54%）只猫吃低豌豆/扁豆（低 PL）饮食，14/37（38%）在诊断时吃高 PL 饮食；3 只猫的饮食信息不完整。在测量牛磺酸的 13 只猫中，有 2 只（15%）的牛磺酸水平低于参考范围。在调整其他变量后，吃高 PL 饮食且在诊断后改变饮食的猫的生存时间明显长于吃高 PL 饮食且在诊断后未改变饮食的猫（P=0.025）。
需要进一步研究以确定猫的饮食与 DCM 之间是否存在可能的关联。
