概括

跨导管大动脉置换 (TAVR) 后的新心脏起器植入并没有显著影响1年的结果,尽管心力衰竭住院病例增加. 这一发现对于理解TAVR并发症和患者管理至关重要.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
心脏外科手术心脏外科手术

背景情况:

需要永久心脏起器植入 (PPI) 的新导电异常是经过过导管大动脉置换 (TAVR) 后已知的并发症.
之前关于TAVR后新型PPI临床影响的研究已经产生了不一致的结果,需要进一步调查.

研究的目的:

通过使用倾向性得分匹配 (PSM) 来比较TAVR患者的1年临床结果,有和没有新的永久心脏起器植入 (PPI).
评估PPI后接受右心室节拍治疗的患者的主要不良心脏事件 (MACE).

主要方法:

这项研究利用了前性观察性 CONDUCT 注册表的数据,招募了接受TAVR的295名患者.
在160名患者 (36名PPI患者,124名无PPI患者) 进行了一到四的倾向分数匹配 (PSM) 分析,以比较结果.
临床结局和主要心脏不良事件 (MACE) 在1年的随访中进行了评估.

主要成果:

一年后,PPI患者呈现了更高MACE的趋势 (22.2%对13.7%),主要是由于心力衰竭住院增加 (11.1%对2.4%).
在PPI和非PPI组之间,所有原因的死亡率,心血管死亡,中风和内心炎的自由性是可比的.
虽然糖尿病患病率和左心室喷射率的基线差异存在,但在PSM后它们减少了.

结论:

尽管在需要PPI的TAVR患者中心力衰竭再住院的发病率较高,但整体1年的临床结果在各组之间是相似的.
这些发现表明,虽然PPI与心力衰竭等特定并发症有关,但可能不会显著改变TAVR后更广泛的1年临床轨迹.

Cardiomyopathy 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,...
