概括

在跨导管大动脉置换 (TAVR) 前的高体积指数 (SVI) 表明系统性拥堵,并预测心脏死亡或心力衰竭再入院的风险更高.

科学领域:

心脏病学心脏病学
放射学放射学是一门学科.
血管生物学血管生物学

背景情况:

脏的大小随着血液动力学波动而波动,充当血液体积缓冲器.
已经注意到心力衰竭和脏大小之间的联系,脏大小作为预后因素.
在接受过导管大动脉置换 (TAVR) 的患者中大小的临床意义尚不清楚.

研究的目的:

为了研究在TAVR之前患者的脏体积的预后影响.
为了确定脏体积是否可以预测TAVR后的不良心脏事件.

主要方法:

在2015年至2022年期间接受TAVR治疗的343名患者的回顾性分析.
从TAVR前的腹部CT扫描中测量体积.
索引体积 (SVI) 与2年心脏死亡或心力衰竭再入院之间的关联的评估.

主要成果:

较高的SVI与血体积增加和系统性拥堵相关.
SVI独立地与2年心脏病死亡或心力衰竭再入院的风险更高有关 (HR1.09,p=0.041).
截止值SVI为70.2毫升/平方米,确定患者具有显著更高的不良事件率 (10%对4%,p=0.033).

结论:

升高的基线SVI表明系统性拥堵,并预测TAVR后更糟糕的结果.
在TAVR群体中,SVI可以作为一个有价值的预后标志物.
需要进一步的研究来阐明心脏-脏关系和SVI在TAVR患者中的作用.

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...
