概括

结节在支架边缘比本土血管更常见,增加了支架后发生重大心脏不良事件的风险. 这凸显了在支架安置时考虑负荷的重要性.

科学领域:

心血管研究的心血管研究.
干预性心脏病学干预性心脏病学
医学成像医学成像

背景情况:

冠状动脉支架可以改变局部血管动态.
支架边缘和化结节 (CN) 形成之间的确切关系需要进一步研究.

研究的目的:

为了研究与本地化病变相比,在支架边缘出现化结节 (CNs) 的频率.
为了确定与在支架边缘的CN发展相关的因素.
评估支架边缘CNs对主要心脏不良事件 (MACE) 的临床影响.

主要方法:

光学连贯断层扫描 (OCT) 用于在801名患者中评估989个支架边缘化病变和354个无支架本地化病变.
病变的分类是基于CN的存在或不存在以及它们是否位于支架边缘或本土血管.
进行了统计分析,包括几率比率 (ORs),以确定CN存在和MACE的预测因素.

主要成果:

在支架边缘化病变 (15.7%) 与本地化病变 (5.1%) (P<0.001) 相比,化结节 (CNs) 的患病率明显高.
支架边缘位置,较大的负荷 (长度,弧度,厚度) 和较大的缩 - 扩张角度变化预测了CN的存在.
支架边缘的CN与MACE的更高率 (15.9%与6.5%,P=0.01) 相关,主要是由目标病变再血管化驱动的.

结论:

支架边缘似乎会导致化结节的发展.
支架边缘CN的存在与严重心脏不良事件的风险增加有关,无论病变治疗状态如何.

Notch Signaling Pathway

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
