概括

在接受冠状动脉旁路移植 (CABG) 的患者中,将非心房切割手术切除 (NASA) 添加到左心房尾封闭 (LAAO) 显著降低了术后心房动 (POAF). 这种综合方法也减少了出院后对抗节律失常药物的需求.

科学领域:

心脏病学心脏病学
心脏外科手术心脏外科手术
电子生理学电子生理学

背景情况:

手术后心房动 (POAF) 是心脏手术后的常见并发症.
目前减少POAF的策略包括后心周切除术和肺静脉隔离.
预防性左心房尾闭塞 (LAAO) 越来越多地用于预防POAF相关的中风.

研究的目的:

为了比较POAF发生率在接受预防性LAAO的患者中,有或没有预防性非心房切割手术切除 (NASA).

主要方法:

追溯观察队列研究,将LAAO单独 (n=90) 与NASA+LAAO (n=42) 在首次隔离冠状动脉旁路移植 (CABG) 患者中进行比较.
从2020年7月到2022年11月收集的数据.
住院POAF根据胸腔外科医生协会 (STS) 标准定义;标准的STS结果和医院费用进行了检查.

主要成果:

群体之间没有人口统计学,操作特征或重大并发症的显著差异.
与仅LAAO (41.1%;P <.0001) 相比,NASA+LAAO组 (4.7%) 的住院POAF率明显较低.
在NASA+LAAO组 (7.3%) 与LAAO组 (42.5%;P <.0001) 之间,释放时使用阿米奥达龙的比例明显较低.

结论:

在接受LAAO的孤立CABG患者中,预防性NASA与住院POAF的显著减少有关.
合并的NASA+LAAO方法还减少了对放出后抗失律药物的需求.
需要进一步的随机对照试验来证实这种联合策略的安全性和有效性.

Disturbances in Heart Rhythm

Disturbances in Heart Rhythm

Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Dysrhythmias VI: Management of Dysrhythmias

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...
