概括
心房动 (AF) 常见于跨导管大动脉置换 (TAVR) 患者,永久心脏起器植入 (PPI) 率高. 基线右捆分支块和门类型预测PPI,这不会影响长期死亡率.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 心脏电生理学 心脏电生理学
背景情况:
- 心房动 (AF) 是通过导管的大动脉置换 (TAVR) 的患者经常出现的心律失常.
- 有限的数据存在于永久心脏起器植入 (PPI) 的预测因子在TAVR患者与AF.
- 了解这些因素对于优化患者护理和结果至关重要.
研究的目的:
- 为了确定TAVR患者中AF的患病率.
- 在这个队列中确定30天PPI的预测因子.
- 调查PPI与3年死亡率之间的关联.
主要方法:
- 一项历史性队列研究包括1579名在2008年至2022年期间接受TAVR的患者.
- 排除标准包括先前的大动脉生物假体或心脏起器.
- 单变量和多变量分析评估了30天的PPI和3年死亡率.
主要成果:
- 在1579名患者中,有405人 (25.6%) 患有AF. 30天的PPI比率为21.7%.
- 右捆分支块 (RBBB) 和CoreValve/Evolut类型是PPI的重要预测因素.
- PPI与3年死亡率的增加没有显著关联.
结论:
- 在TAVR患者中,AF很普遍,PPI率很高.
- 在AF患者中,PPI的预测因子与鼻节律患者的预测因子相似,包括RBBB和门类型.
- 在TAVR患有AF的患者中,高PPI率似乎不会影响长期死亡率.

01:30Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:29Cardiomyopathy V: Interprofessional Care
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
