慢性心力衰竭(CHF)患者1/4以上均死于心源性猝死(SCD)。埋藏式心脏复律除颤器(ICD)随着心血管循证医学的快速发展其适应征在近年来得到了显著的拓展,包括对CHF患者SCD的一、二级预防。对于同时具有ICD及心脏再同步化治疗指征的患者,两者联合应用可进一步改善患者的预后。积极探讨如何对CHF患者进行SCD的危险分层,从中识别出哪些患者能从ICD中获益具有重要的现实意义。 More than a quarter of patients with chronic heart failure (CHF) die of sudden cardiac death (SCD). Buried cardioverter defibrillators (ICDs) With the rapid development of cardiovascular evidence-based medicine, their indications have been significantly expanded in recent years, including primary and secondary prevention of SCD in CHF patients. For patients with both ICD and cardiac resynchronization therapy indications, the combination of the two can further improve the patient’s prognosis. It is of great practical significance to explore how to stratify the risk of SCD in CHF patients and identify which patients can benefit from ICD.
