概括
在接受左心房附属体关闭 (LAAC) 的患者中,自发回声对比度 (SEC) 较高与血栓栓塞事件和设备相关血栓 (DRT) 的风险增加相关. 结合SEC等级和心房动 (AF) 类型可以更好地预测这些不良结果.
科学领域:
- 心血管医学 心血管医学
- 干预心脏病学 干预心脏病学
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
背景情况:
- 在心房 (AF) 中,自发回声对比 (SEC) 是已知的中风风险因素.
- 不同的SEC等级对左心房附属体关闭 (LAAC) 后的结果的影响尚未得到充分证实.
研究的目的:
- 调查手术前自发回声对比度 (SEC) 和左心房附带关闭 (LAAC) 后的临床结果之间的关联.
- 为了确定SEC等级是否可以独立预测LAAC后的不良事件.
主要方法:
- 对1276名连续接受LAAC.患者的分析.
- 患者被分为SEC 0+,SEC 1/2+和SEC 3/4+分层,这些分层是基于跨食道心声学.
- 在SEC组中比较临床结果,包括缺血性中风,短暂缺血性发作,全身栓塞和与设备相关的血栓 (DRT).
主要成果:
- 与较低等级相比,最高的SEC等级 (3/4+) 与缺血性中风/暂时性缺血性攻击/全身血栓塞的发生率显著更高 (P=0.009对于SEC 0+和3/4+).
- 无论是SEC 1/2+ (8.4%) 还是SEC 3/4+ (12.4%) 组,与SEC 0+组 (2.8%) 相比,与设备相关的血栓 (DRT) 的风险明显增加 (P < 0.001).
- 对SEC等级和AF类型的综合评估显示,SEC 3/4+与非气囊性AF独立预测了血栓栓塞事件 (aHR:2.52) 和DRT (aHR:2.89).
结论:
- 增加自发回声对比度 (SEC) 级别与左心房附属物关闭 (LAAC) 后发生血栓栓塞事件和设备相关血栓 (DRT) 的风险更高有关.
- SEC等级和心房动 (AF) 类型的组合作为这些不良结果的独立预测因素.
- 需要进一步的研究,以优化对接受LAAC的严重SEC患者的治疗策略.

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
