概括
通过心脏植入式电子设备 (CIED) 检测到的心房高频发作 (AHREs) 表明血栓栓塞风险较低. 任何AHRE的存在,无论持续时间如何,都应为对血栓栓塞事件的患者特异性风险评估提供信息.
科学领域:
- 心脏病学 心脏病学
- 电子生理学 电子生理学
- 医疗器械 医疗器械
背景情况:
- 心房高频发作 (AHREs) 经常被心脏植入式电子设备 (CIED) 检测出来.
- 临床指南缺乏对AHREs的普遍定义和预测血栓栓塞事件的明确时间值.
- 这种模糊性需要研究来定义临床上显著的AHREs.
研究的目的:
- 确定通过心脏植入式电子设备 (CIED) 检测到的临床显著心房高频发作 (AHREs) 的最佳时间值.
- 通过对诊断测试准确性的元分析,分析AHRE持续时间和随后的血栓栓塞事件之间的关联.
主要方法:
- 在PubMed/MEDLINE和EMBASE进行了系统的文献搜索,寻找在CIED患者中报告AHREs和血栓栓塞事件的研究.
- 对23项研究进行了随机效应诊断测试准确度元分析,分析了最长的单个AHREs和AHRE负担.
- 进行了敏感性分析,排除了先前心房的患者,只包括了高质量的研究.
主要成果:
- 对于最长的单个AHRE,确定了0.07分钟的最佳持续时间 (灵敏度为65.4%,特异性为52.7%,AUC-SROC为0.62).
- 对于AHRE负担,最佳切断时间为1.4分钟 (灵敏度为58.2%,特异性为57.5%,AUC-SROC为0.60).
- 敏感性分析也得出了类似的结果,加强了主要的发现.
结论:
- 在患有心脏植入式电子设备 (CIED) 的患者中,任何心房高频发作 (AHRE) 的存在,而不是特定的持续时间,与血栓栓塞风险略有增加有关.
- 应考虑AHREs作为一个额外的因素,在CIED患者对血栓栓塞风险的个性化评估.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
