Plain-English summary

A litter of five 18-month-old mixed-breed cats was found to have hypertrophic cardiomyopathy (HCM), a heart condition that can lead to serious issues. While none of the cats showed obvious symptoms, all had heart murmurs detected during a vet check. Further tests, including echocardiograms, confirmed the presence of HCM. Fortunately, two years after their diagnosis, all the cats remain healthy and show no clinical signs of the disease.

Abstract

A litter of five, 18-month-old, mixed-breed cats were determined to have hypertrophic cardiomyopathy (HCM). Although no overt clinical signs were present in any cat, systolic heart murmurs were present in each. Electrocardiograms were normal, while subjective interpretations of heart enlargement on radiographs were made on four cats. Echocardiographic analyses indicated abnormalities consistent with HCM. Overt clinical signs are absent two years following diagnosis.
