概括
高风险穿皮冠状动脉干预 (SHiPCI) 的单次接入比双次接入更安全,并发症较少. 这种用于Impella辅助无保护左主PCI (UPLM-PCI) 的技术导致较少的不良事件和严重出血.
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:
- 高风险穿皮冠状动脉干预 (SHiPCI) 单次接入技术为传统的双重接入提供了潜在的替代方案.
- 有限的数据存在,主要来自回顾性病例研究,需要进一步调查SHiPCI的疗效和安全性.
研究的目的:
- 为了比较高风险穿皮冠状动脉干预 (SHiPCI) 的单次接入和Impella辅助无保护左主PCI (UPLM-PCI) 的双重接入之间的程序并发症和临床结果.
主要方法:
- 一个单一中心的回顾性观察性研究包括从2018年到2023年接受高风险无保护左主PCI (UPLM-PCI) 的患者.
- 患者的倾向性得分在单次访问 (SHiPCI) 和双次访问Impella辅助的UPLM-PCI组之间与1:1匹配.
- 主要结局是住院死亡率,严重出血,血管接入部位并发症和输血的复合.
主要成果:
- 在每个组中,有50名患者被匹配 (单次与双重访问).
- 单次访问组的初级复合结果率明显较低 (14%对32%,p=0.033).
- 在单次接入组中,主要出血率明显较低 (2%对17%,p=0.014).
结论:
- 与Impella辅助的UPLM-PCI双接入相比,SHiPCI的复合结局率较低,主要是由于大出血减少.
- 建议通过前性随机对照试验进行进一步验证,以确认SHiPCI的有效性和安全性.

Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
Cardiomyopathy V: Interprofessional Care
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...
