概括
冠状动脉鼻腔隔离 (CSI) 与肺静脉隔离 (PVI) 和单独用于高负荷心房动 (AF) 的屋顶线切除相比,没有改善心房律乱无生存率. 这种辅助策略在长期结果方面没有显著的好处.
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:
- 冠状动脉鼻涉及启动和维持心房动 (AF).
- 冠状动脉鼻腔切除可以延长AF周期的长度并终止AF,特别是在持续AF的肺静脉隔离后患者中.
研究的目的:
- 评估冠状动脉鼻隔离 (CSI) 作为高负荷AF的附加废除策略的疗效.
- 进行一项随机对照试验,比较CSI加PVI/屋顶线与PVI/屋顶线单独.
主要方法:
- 100名患有高负荷AF的患者被随机分配到PVI,屋顶线和CSI,或仅PVI和屋顶线.
- 主要结局是单次手术后2年无药无心律失常的生存期.
- 随访包括临床评估和为期7天的霍尔特监测.
主要成果:
- 在CSI组 (62.5%) 和非CSI组 (63.4%) 之间,单次手术的两年无药生存时间没有显著差异.
- 在5年后的多重手术药物辅助存活率没有差异.
- 两组之间并发症的发生率相似.
结论:
- 辅助冠状动脉鼻隔离 (CSI) 不提供额外的好处比PVI和屋顶线移除高负荷AF的de novo治疗.
- 在实现长期心律不律的自由方面,CSI并不优于标准的PVI和屋顶线切除.

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...
