概括
在左心室辅助装置 (LVAD) 植入之前评估右心室肺动脉 (RV-PA) 合可以预测患者的结果. 较差的RV-PA合表明死亡或右心力衰竭住院的风险更高.
科学领域:
- 心脏病学 心脏病学
- 心血管外科心血管外科
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 右心室 (RV) 功能和肺动脉 (PA) 压力对于左心室辅助器件 (LVAD) 患者的结果至关重要.
- 在这个人群中,RV-PA合的预后意义仍然不清楚.
研究的目的:
- 在接受LVAD植入的患者中调查RV-PA合的预后影响.
主要方法:
- 对72名第三代LVAD患者的回顾性分析.
- 在手术前使用RV自由壁应变 (RVFWS) 和峰值RV缩压 (RVSP) 评估RV-PA合.
- 主要终点:综合所有原因死亡率或右心力衰竭 (RHF) 住院.
主要成果:
- 对于RVFWS/TAPSE的0.28%/mmHg的切线在26.4%的患者中发现了先进的RV-PA脱.
- 晚期RV-PA脱患者的死亡率或RHF住院率明显较高 (89.47%与30.19%,p < 0.001).
- 所有原因的死亡率和RHF住院率在未结合组中也显着更高.
结论:
- 先进的RV功能障碍,由RV-PA脱表明,是LVAD患者不良结果的显著预测因素.
- 评估RV-PA合可能有助于对LVAD候选者的风险分层和管理.

Mitral Stenosis I: Introduction
19
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

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,...
