Heart failure is a clinical syndrome caused by various causes of myocardial damage and cardi-ac function decrease that cannot meet the body's metabolic needs.The proinflammatory cytokines play an im-portant role in the process of occurrence and development of heart failure.The Notch1/Jagged1 signaling path-way is related to the proinflammatory cytokines,inflammatory responses and immune responses.This paper discusses the involvement of the Notch1/Jagged1 signaling pathway in the development and development of chronic heart failure by modulating immune inflammation.
