Background
Chronic inflammation contributes to the progression of isoproterenol (ISO)‐induced heart failure (HF). Caspase‐associated recruitment domain (CARD) families are crucial proteins for initiation of inflammation in innate immunity. Nonetheless, the relevance of CARDs in ISO‐driven cardiac remodelling is little explored.
