概括
超动态左心室 (LV) 缩功能影响了18.2%的败血症患者,并与2.37倍的短期死亡风险增加有关. 这种状况的特点是高LV喷射率 (LVEF),在败血症管理中需要进一步的临床关注.
科学领域:
- 心脏病学 心脏病学
- 关键护理医学 关键护理医学
- 内部医学 内部医学
背景情况:
- 败血症是一种危及生命的器官功能障碍,其原因是宿主对感染的反应失调.
- 左心室 (LV) 缩功能在败血症中的特征,特别是高动态的LV缩功能,以及它们的预后影响尚未完全理解.
- 超动态的 LV 缩功能,定义为高的 LV 喷射分数 (LVEF),在败血症患者中不一致报告.
研究的目的:
- 系统地审查和元分析患有败血症的成年患者中高动态LV缩功能的患病率.
- 调查高动态LV缩功能与败血症患者的短期死亡率之间的关联.
- 探索二次结果,包括心率,LV终端-透气直径 (LVEDD) 和E/e'比.
主要方法:
- 在MEDLINE,科克伦控制试验中央注册表和Embase的系统文献搜索.
- 包括四项研究进行元分析.
- 使用70%的LVEF截止值来定义高动态LV缩功能的定义.
主要成果:
- 在败血症患者中,高动态 LV 系统功能的综合患病率为 18.2% (95% CI 12.5,25.8).
- 超动态 LV 缩功能与较高的短期死亡率显著相关 (OR 2.37;95% CI 1.47,3.80).
- 患有高动态LV缩功能的患者表现出更高的心率和LVEDD,但与正常LV功能患者相比,E/e'比率没有显著差异.
结论:
- 超动态 LV 缩功能是相当大比例的败血症患者的显著发现.
- 这种情况独立地与败血症短期死亡风险的大幅增加有关.
- 这些发现突显了评估LV缩功能在败血症中对于风险分层和管理的重要性.

Pathophysiology of Heart Failure
1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Imbalances in Cardiac Output
1.4K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
