概括
左心室 (LV) 血栓的分辨率比以前认为的要慢,显著的栓塞风险持续超过六个月,特别是在未分辨的血栓患者中. 推使用延长抗凝剂.
科学领域:
- 心脏病学 心脏病学
- 心血管成像 - 心血管成像
- 血栓形成研究研究
背景情况:
- 目前对左心室 (LV) 血栓的治疗缺乏可靠的数据,依赖于较旧的心声回声学研究.
- 人们对栓塞风险和血栓演变模式的了解很少.
- 心血管磁共振成像 (CMR) 是检测LV血栓的黄金标准.
研究的目的:
- 使用连续心血管磁共振成像 (CMR) 调查左心室 (LV) 血栓的演变.
- 为了确定与缺乏血栓分辨率相关的因素.
- 为了评估与LV血栓解决状态相关的栓塞风险.
主要方法:
- 对107名患有LV血栓的患者进行了回顾性队列研究.
- 连续的CMR扫描在诊断后平均255天进行.
- 使用里程碑式方法评估栓塞事件的生存分析.
主要成果:
- 在CMR检测后的3,6个月和12个月,显著比例的LV瘤仍未解决 (分别为75%,53%,和37%).
- 与没有解决相关的因素包括心肌梗塞史,LV动脉瘤,缺血性心肌病和较大的血栓体积.
- 血栓事件在6个月以后更频繁,特别是在未解决的LV血栓患者中.
结论:
- LV 血栓的解决率低于之前报告的水平,血栓风险持续超过 6 个月.
- 在序列CMR上未解决的LV血栓与栓风险的增加有关.
- 延长抗凝治疗对于具有LV血栓分辨率差的标志物的患者是有必要的.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...
