The myocardial microvasculature plays a key role in the pathogenesis of feline hypertrophic cardiomyopathy
This study demonstrates that feline hypertrophic cardiomyopathy is characterized by significant microvascular alterations, including capillary rarefaction, enlarged vessels, and disorganized architecture driven by metabolic stress and vascular developmental pathways, suggesting that microvascular dysfunction is a key driver of the disease's pathogenesis.
