概括

左心室血栓 (LVT) 在ST段升高心肌梗塞 (STEMI) 后发生在17.6%的患者中,尽管进行了初级皮肤穿冠状动脉干预 (PCI). 前部STEMI,减少喷射率和墙壁运动得分指数 (WMSI) 是关键的风险因素.

科学领域:

心脏病学心脏病学
医疗成像医学成像
干预心脏病学干预心脏病学

背景情况:

左心室血栓 (LVT) 是急性ST段升高心肌梗塞 (STEMI) 后的潜在并发症.
在初级穿皮冠状动脉干预 (PCI) 时代,LVT的发病率和风险因素需要持续评估.

研究的目的:

确定急性STEMI后的LVT的频率和识别独立风险因素.
评估各种心电图和心声图参数的诊断能力,以预测LVT.

主要方法:

一项针对131名急性STEMI患者进行的前性研究,这些患者接受了初级PCI治疗.
跨胸腔心声学 (TTE) 用于检测LVT.
分析包括心电图 (Q波,ST偏差,QT分散) 和心声图 (射出分数,体积,墙壁运动得分指数) 参数.

主要成果:

背脊伤的发生率为17.6%.
前部STEMI,较高的墙壁运动得分指数 (WMSI),增加的病理Q波,动脉瘤形成和较低的射出分数 (EF) 是 LVT 的重要危险因素.
在WMSI中,用于检测LVT的诊断功率最高 (AUC为0.910).

结论:

在STEMI后,LVT仍然是一个显著的并发症,即使是初级PCI.
前部STEMI位置,特定的心电图发现,心声谱异常 (WMSI,动脉瘤,低EF) 是LVT的独立预测因素.
WMSI是一个强大的工具,用于识别患有STEMI后LVT风险的患者.

关键词:

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
