概括

突然心脏死亡 (SCD) 和晚期心力衰竭 (HF) 占过导管大动脉置换 (TAVR) 后死亡的显著部分. 识别风险因素,如心律失常和特定的程序发现,可以帮助减轻这些风险.

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:

心脏病死亡的长期负担,特别是从晚期心力衰竭 (HF) 和突然心脏病死亡 (SCD) 来说,经过透气管大动脉置换 (TAVR) 后的死亡并不确立.
当代TAVR结果需要持续评估,特别是关于特定的死亡原因.

研究的目的:

确定使用新一代设备进行TAVR的患者中SCD和HF相关死亡的发生率和预测因素.
为了确定患者的特征和程序因素与增加的SCD风险和TAVR后HF死亡相关.

主要方法:

分析了5421名连续接受TAVR治疗的患者,这些患者使用气球可扩展或自扩展门.
随访时间中位数为2年,以评估死亡原因,包括心血管死亡,先进的HF和SCD.
多变量分析以确定与HF相关的死亡和SCD的独立预测因素.

主要成果:

在随访期间,976例死亡中,心血管原因占50.8% (总体为18.0%).
晚期HF (11.6%) 和SCD (7.5%) 是TAVR后死亡率的重要贡献者.
HF死亡的预测因素包括心房动,先前的起器,减少的射出分数,胸前方法和新发的LBBB;SCD的预测因素包括糖尿病,CKD,门内TAVR,非转靠近和周围手术室心律不整.

结论:

在当代TAVR之后,先进的HF和SCD占死亡人数的很大一部分.
鉴定出了HF死亡 (如心律失常,失同) 和SCD (如门内手术,周围手术心律失常) 的潜在可修改的风险因素.
这些发现突出了风险减轻策略的目标,以改善TAVR后的结果.

关键词:

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Cardiomyopathy 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...
