概括

在心力衰竭患者中,左束枝节奏 (LBBP) 与双心室节奏 (BIVP) 相比,提供稳定的参数和更窄的QRS持续时间. 在HFrEF与CLBBB中,LBBP是心脏再同步治疗的安全有效替代方案.

科学领域:

心脏病学心脏病学
电子生理学电子生理学
心脏衰竭管理的管理

背景情况:

减少喷射分数 (HFrEF) 和完整的左捆分支阻塞 (CLBBB) 的心力衰竭带来了重大管理挑战.
双胞胎节拍 (BIVP) 是一种标准疗法,但生理节拍方法正在出现.
左束枝节奏 (LBBP) 是一种新的技术,旨在实现更自然的心室激活.

研究的目的:

在患有HFrEF和CLBBB的患者中,比较LBBP与BIVP的长期疗效和安全性.
评估两个节奏策略之间的关键节奏参数,心脏功能和临床结果.

主要方法:

从2018年4月到2022年10月,对35名HFrEF和CLBBB患者进行了回顾性分析.
患者被分为LBBP (n=18) 和BIVP (n=17) 组.
收集的数据包括节奏参数,QRS持续时间,心声学指数,NT-proBNP,NYHA类,并发症,再入院和死亡率.

主要成果:

与BIVP相比,LBBP组在手术后12个月显示出明显较低的节奏值和阻抗.
在LBBP组的6,12和24个月后,观察到QRS持续时间显著缩短.
在24个月后,LBBP组的LVEDD和LVESD显著降低;响应率,反,NYHA类,NT-proBNP,死亡率或再录取没有显著差异.

结论:

在患有CLBBB的HFrEF患者中,LBBP显示出有利的节奏参数和QRS缩小.
LBBP似乎是心脏再同步治疗的安全有效替代品.
对于这种患者群体来说,LBBP是BIVP的可行补充方法.

关键词:

双管节奏是双管节奏的节奏.完整的左捆分支区块完成左捆分支区块心脏衰竭是因为心脏衰竭.左捆的分支步行步行步行.

Heart Failure Drugs: β-Blockers

Heart Failure Drugs: β-Blockers

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation,...

Heart Failure Drugs: Inotropic Agents

Heart Failure Drugs: Inotropic Agents

Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
