Feline hypertrophic cardiomyopathy

Feline hypertrophic cardiomyopathy (HCM) is a condition where a cat’s heart muscle, especially the walls of the left ventricle, becomes abnormally thick. This thickening can reduce the heart’s ability to pump blood effectively and may lead to symptoms like difficulty breathing, lethargy, or even sudden collapse. Sometimes, cats show no signs. HCM is a common heart disease in cats, often inherited, and diagnosis involves ultrasound imaging. Treatment may include medications to improve heart function and decrease the risk of blood clots. Regular veterinary check-ups are important for managing and monitoring the condition.
