目的：确定健康成年缅因猫M型超声心动图参数的参考值，并与未隔离的健康成年家猫的M型超声参数进行比较。设计前瞻性研究：动物-105只健康成年缅因猫。过程-在3年的时间里，对缅因猫进行了M型超声心动图检查(包括标准的右侧胸骨旁经胸骨技术)，收集健康个体的M型超声心动图参数值，并计算平均值与报道的健康成年家猫的M型参数进行比较。结果：缅因州猫的平均+/-SD体重显著大于家猫。缅因猫左室舒张末期内径(LVIDd)、收缩末期内径(LVIDs)、收缩末期室间隔厚度(IVSS)、收缩末期左室后壁厚度(LVPWs)、收缩末期左房内径(LAD_1)和主动脉根部内径(Ao)的平均值与健康家猫有显著差异。两组之间检测到的最大差异涉及LVIDd、LAD和Ao的值。线性回归分析显示体重与LVIDd、LVPWs、IVSS、IVSS、Ao、LAD(S)和舒张末左室后壁厚度之间存在微弱但显著的相关性。结论和临床相关性-缅因州孔猫的几个M型超声心动图参数与家猫不同；在解释该品种的超声心动图结果时，应考虑这些差异，以区分该品种的心脏健康和疾病。
Objective - To determine reference values for M-mode echocardiographic parameters in nonseclated healthy adult Maine Coon cats and compare those values with data reported for nonseclated healthy adult domestic cats.Design - Prospective study.Animals - 105 healthy adult Maine Coon cats.Procedure - Over a 3-year period, M-mode echocardiographic examinations (involving a standard right parasternal transthoracic technique) were performed on Maine Coon cats as part of prebreeding evaluations' values of M-mode parameters in healthy individuals were collected, and mean values were calculated for comparison with those reported for healthy adult domestic cats.Results - The mean +/-SD weight of Maine Coon cats was significantly greater than that of domestic cats. Mean values of left ventricular internal dimension at end diastole and end systole (LVIDd and LVIDs, respectively), interventricular septal thickness at end systole (IVSs), left ventricular posterior wall thickness at end systole (LVPWs,), left atrial dimension at end systole (LAD,), and aortic root dimension (Ao) in Maine Coon cats differed significantly from values in healthy domestic cats. The greatest differences detected between the 2 groups involved values of LVIDd, LAD,, and Ao. Linear regression analysis revealed a weak but significant correlation between weight and each of LVIDd, LVPWs, IVSs, IVSs, Ao, LAD(s), and left ventricular posterior wall thickness at end diastole.Conclusions and Clinical Relevance - Values of several M-mode echocardiographic parameters in Maine Coon cats differ from those reported for domestic cats; these differences should be considered during interpretation of echocardiographic findings to distinguish between cardiac health and disease in this breed.
