概括

使用Impella进行高风险穿皮冠状动脉干预 (HR-PCI) 的机械循环支持显示,在非Impella队列中,类似的住院主要不良心脏事件 (MACE),但90天的MACE较少. 结果不支持在HR-PCI中常规使用Impella.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
医疗器械医疗器械

背景情况:

在高风险穿皮冠状动脉干预 (HR-PCI) 中,Impella机械循环支持的疗效仍然不确定.
像PROTECT III这样的先前研究表明,Impella的治疗结果有所改善,但没有直接与没有支持的HR-PCI进行比较.

研究的目的:

通过使用PROTECT III纳入标准,比较了接受Impella支持的HR-PCI患者和没有接受Impella支持的患者的结果.
在HR-PCI中评估Impella的安全性和有效性,通过将非Impella队列与PROTECT III注册表中的Impella队列进行比较.

主要方法:

追溯分析将非Impella HR-PCI队列与PROTECT III注册表中的Impella队列进行比较.
使用逆倾向权重来平衡两个组之间的基线特征.
主要终点是住院和90天的主要不良心脏事件 (MACE).

主要成果:

在住院MACE (3.0%对4.8%,p=0.403) 中没有发现显著差异.
非Impella组的90天MACE显著减少 (7.5%对13.8%,p=0.033).
在非Impella组中观察到急性损伤率较高 (10.5%与5.4%,p=0.023),血管并发症或出血没有差异.

结论:

在相同的HR-PCI标准下,非Impella队列与Impella队列相比,在医院内经历了类似的MACE,但90天的MACE较少.
没有与使用Impella相关的周围手术伤害.
这些发现不支持Impella在所有高风险皮肤冠状动脉干预患者的常规使用.

关键词:

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
