概括
在等待心脏移植 (HT) 的高级心力衰竭患者中,术前使用levosimendan并没有增加早期移植后并发症,如血管或初级移植功能障碍 (PGD). 这项研究表明,levosimendan在HT之前是一个安全的策略.
科学领域:
- 心脏病学 心脏病学
- 移植医学 移植医学
- 药理学 药理学是指药理学的学科.
背景情况:
- 莱沃西门丹是一种用于预先心力衰竭 (HF) 患者等待心脏移植 (HT) 的内otropic 药物.
- 它的长期作用可能会影响HT后血管扩张和诸如血管和初级移植功能障碍 (PGD) 等并发症.
- 术前levosimendan对这些早期移植后结果的影响尚不清楚.
研究的目的:
- 评估术前levosimendan的使用是否会影响HT后血管和严重PGD的发病率.
- 评估levosimendan在直接移植前期使用的安全性.
主要方法:
- 成年HT接受者的回顾性多中心观察研究 (2010-2022年).
- 根据在HT前一个月内使用levosimendan的情况,患者被分组为组.
- 结果包括HT后血管,严重的PGD (ISHLT标准) 和全因死亡率,分析使用倾向得分匹配和考克斯回归.
主要成果:
- 在598名HT接受者中,有94人接受了手术前的levosimendan.
- 在倾向得分调整后,在血管 (40.0%对39.2%) 或严重的PGD (10.6%对10.3%) 之间没有观察到显著差异.
- 所有原因的死亡率也相似 (HR 0.78,p=0.37),严重的PGD与较高的死亡率有关.
结论:

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
