概括
冠状动脉旁路移植 (CABG) 手术减少左心室 (LV) 纵向功能. 然而,这种下降是通过改善手术期间LV周围应变和旋转来补偿的.
科学领域:
- 心脏病学 心脏病学
- 心脏外科手术 心脏外科手术
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 在冠状动脉旁路移植 (CABG) 可以损害左心室 (LV) 纵向功能.
- 对这种功能衰退的补偿机制尚不清楚.
- 心肌应变分析为LV收缩模式提供了详细的视图.
研究的目的:
- 通过在内CABG后的心肌张力分析来调查LV收缩模式的手术内变化.
- 为了确定LV纵向功能减少的补偿机制.
主要方法:
- 一项前性观察性研究,涉及30名接受内CABG的患者.
- 经食道回声心脏图用于评估三个时间点的LV功能:麻醉前,心肺旁路后和关闭后.
- 分析包括LV喷射分数,全球纵向应变 (GLS),全球环形应变 (GCS),全球辐射应变 (GRS),顶点和基点旋转以及LV扭曲.
主要成果:
- 与绕道前测量相比,CABG后GLS显著下降.
- 手术后GCS,LV顶旋转,基底旋转和LV扭转显著改善.
- 在手术期间,没有观察到LV喷射分数或GRS的显著变化.
结论:
- 内手术内CABG导致LV纵向功能的减少.
- 这种减少被LV周围应变和旋转的改善所补偿.
- 对应变和旋转的术后评估为心脏力学提供了宝贵的见解.

Cardiomyopathy VII: Pre and Post Operative Nursing Management
16
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy III: Hypertrophic Cardiomyopathy
16
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
