Risk factors, clinical signs, and survival in cats with a clinical diagnosis of idiopathic hypertrophic cardiomyopathy: 74 cases (1985-1989).

摘要: Population characteristics, risk factors, and survival characteristics were evaluated in 74 cats with hypertrophic cardiomyopathy (HC) seen at North Carolina State University veterinary teaching hospital from 1985 to 1989, compared 82 clinically normal cats. The mean (+/- SD) age of HC was 6.5 (4.0) years. Neutered males significantly greater (odds ratio 3.1) than neutered females. Breed, body weight, or coat color not determined be factors for HC. Tricolor underrepresented, probably reflecting the male predisposition a true reduction associated color. Forty-one without clinical signs heart disease (murmur and/or gallop sound only), 24 congestive failure, 9 had systemic arterial embolism, 3 which concomitant failure. median time 61 HC, information could obtained that euthanatized on day 1, 732 days. Survival affected by diagnosis, breed, sex. However, important determining prognosis; rates 200 beats/min survived longer (median 1,830 days) those equal = 152 days). Cats signs, failure 92 days, days embolism. Analysis revealed no significant difference between 2 groups signs; however, all embolism only 60% dead 6 months after diagnosis.
