心音在慢性心力衰竭诊疗中的应用研究进展

Advances in application of heart sounds in diagnosis and treatment of chronic heart failure

心音是心脏机械运动所产生的振动信号,能够直接反映心脏血流动力的改变,本文综述了心音在慢性心力衰竭中的应用研究进展,包括心音在左心室功能障碍评估与慢性心衰辅助诊断、慢性心衰分型鉴别、心衰治疗指导和预后预测方面的应用,最后梳理了心音在心血管疾病中的研究现状,展望了未来的研究方向和趋势,为心音在临床诊疗中的应用提供参考。

Heart sounds are the vibrations generated by cardiac mechanical movement and can directly reflect the changes of cardiac hemodynamic features.Herein the research advances in application of heart sounds in chronic heart failure(CHF)are reviewed from the aspects of the assessment of left ventricular dysfunction,auxiliary diagnosis of CHF,classification of heart failure phenotypes,treatment guidelines and prognosis prediction for CHF.Finally,the research status of heart sounds in cardiovascular diseases is summarized,and the future research direction and trend are also prospected,aiming to provide a reference for the application of heart sounds in clinical diagnosis and treatment.
