Prevalence of feline cardiomyopathy phenotypes and arterial thromboembolism

Abstract

The aim: To investigate the prevalence of cardiomyopathy (CMP) phenotypes and the weight of cardiogenic arterial thromboembolism (ATE) as a complication in cats. To determine the influence of age, breed and sex on the frequency of detection of CMP and ATE. Animals: One hundred and seventeen cats with various phenotypes of cardiomyopathies. Materials and methods: the database of the veterinary center was analyzed. From 1066 studied cats, 117 stories of animal diseases were selected, in which the diagnosis of cardiomyopathy was established. Results: In the experimental group, the prevalence of CMP was 11 % (HCMP - 94 %; DCMP - 3.4 %; RCMP - 2.6 %). Males were affected more often and had a more severe course. As the age of the animals increased, the relative frequency of heart failure increased slightly, but CMP was diagnosed more often in young animals. The Scottish Straight, Scottish Fold, European Shorthaired, European Longhaired, British Longhaired, and Canadian Sphynx can be considered susceptible breeds in Vinnytsia. There have been no cases of cardiomyopathy in Maine Coons. 57 % of cats with HCMP phenotype were asymptomatic. Arterial thromboembolism occurred in 14.5 % of animals with various CMP phenotypes. The lethality of ATE before discharge was 17.6 %, euthanized (different time period after the incident) 29 %. Conclusion: HCMP phenotype is the most common. Probably, genetic factors related to sex and breed have a significant influence on the development of cardiomyopathy. More often, CMP phenotypes were diagnosed in younger animals. Heart failure develops more often in older animals. The number of animals with ATE and HCMP phenotype is high, but relative to the number of animals with heart failure, cats with DCMP were more prone. ATE occurred more often in females. Thromboembolism is more common in the European Longhair breed.
