概括

高级心声回声显示,静心后应变指数 (PSI) 和静心形成,而不是全局应变或射出分数,在儿科扩张性心肌病患者中有效区分心力衰竭的严重程度.

科学领域:

儿童心脏病学儿童心脏病学
心血管成像 - 心血管成像
心脏衰竭病理生理学病理生理学

背景情况:

扩展性心肌病 (DCM) 在儿童中显著损害心脏功能.
目前的心声回声学方法在评估儿科DCM的功能状态方面存在局限性.

研究的目的:

为了确定与儿科DCM患者的功能状态更好地相关联的回声心脏学参数.
为了比较先进的心声回声技术在区分心力衰竭严重性的有效性.

主要方法:

在28名DCM患者 (NYHAII-III类) 和30名对照中使用了先进的心声回声学,包括组织多普勒和2D斑点跟踪.
评估左心室 (LV) 功能,计算全球纵向应变 (GLS),全球区域应变 (GAS),射出分数 (EF),后静脉应变指数 (PSI) 和LV vortex形成时间.

主要成果:

全球菌株 (GLS,GAS) 和射出分量 (EF) 并没有区分NYHAII和III分组.
后静脉应变指数 (PSI) 和静脉形成时间在NYHA II和III病例之间有显著差异.
在33%的NYHA II患者和77%的NYHA III患者中观察到静脉形成;PSI切断>4%预测了92%的敏感性更糟糕的结果.

结论:

心脏失调在儿科DCM症状表现中起着至关重要的作用.
血斑跟踪用于评估LV vortex形成是一个有前途的床边工具,用于评估心力衰竭的严重程度.
为了客观的临床应用,需要进一步标准化血斑跟踪.

Cardiomyopathy II: Dilated Cardiomyopathy

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
