【 摘 要 】

References(13)Cited-By(1)Examination of our necropsy records for the period 2005 to 2014 yielded 41 cases of theendomyocardial form of restrictive cardiomyopathy among 327 cats with evidence of heartdisease, and here, we reviewed their epidemiological and clinical features. The medicaldata obtained retrospectively included signalment, presenting complaints, findings ofphysical examination, results of various diagnostic tests, methods of treatment andsurvival times. Except for one Chinchilla Persian cat, all were domestic short-hairedcats. The mean age at death was 7.3 ± 4.5 years (median, 6 years; range, 4 months to 19years), and males accounted for 61% (25/41) of the total. Dyspnea was the most commonclinical sign, being evident in 83% (35/41) of the cats. Hind limb paresis or paralysisdue to aortic thromboembolism was evident in 41% (17/41). Arrhythmias of atrial originwere common. Echocardiography commonly revealed left atrial or biatrial enlargement withsevere endocardial thickening of the left ventricle. Most of the affected cats had a pooroutcome; the disease duration ranged from 1 to 977 days, and the median survival periodwas 30 days.
