Abstract: Hypertrophic cardiomyopathy is one of the most common primary heart diseases in cats, which is characterized by left ventricular hypertrophy. Myocardial fibrosis is a cardinal pathological change in cats with hypertrophic cardiomyopathy, which can lead to cardiac dysfunction and rhythm disturbance, and it is an important factor contributing to poor prognosis of cats with cardiomyopathy. There is an urgent need to develop novel drugs targeting cat hypertrophic cardiomyopathy and cardiac fibrosis. This review summarizes the pathological characteristics of cat hypertrophic cardiomyopathy as well as most updated research progress on the pathogenesis of cat myocardial fibrosis, aiming to find a breakthrough point for new therapeutic drug development for cat hypertrophic cardiomyopathy.

Key words: hypertrophic cardiomyopathy, myocardial fibrosis, fibroblast, myofibrolast
