概括
接受冠状动脉旁路移植 (CABG) 的需要透析的患者面临显著更高的死亡率和不良事件. 动脉移植在这些高危人群中没有生存益处,因此需要透析特定的风险模型.
科学领域:
- 心血管外科心血管外科
- 腎臟病學 (nephrology) 是一種醫學專業.
- 研究成果 研究成果 研究成果
背景情况:
- 在透析依赖 (DD) 患者中冠状动脉旁路移植 (CABG) 提出了相当大的挑战和较差的结果.
- 尽管手术的进展,DD患者仍然是一个高风险群体,存活时间有限.
- 了解接受CABG的DD患者的具体风险和益处至关重要.
研究的目的:
- 将透析依赖 (DD) 和非透析依赖 (NDD) 患者之间的CABG结果进行比较.
- 在DD患者中确定死亡率和主要心脏和脑血管不良事件 (MACCE) 的预测因素.
- 评估动脉移植的有效性和EuroSCORE II在这个人群中的预测准确性.
主要方法:
- 追溯队列研究比较97名DD患者与488名NDD对照从2010年至2015年.
- 主要终点:所有原因的死亡率. 二级终点:MACCE. 这就是第二个终点.
- 平均随访时间为5.4年;分析包括风险因素识别和EuroSCORE II绩效评估.
主要成果:
- 在DD患者中,术后死亡率显著增加 (10.3%与3.1%相比),整体5年生存率降低 (40.8%与82.1%相比).
- 透析依赖增加了8.4倍的死亡风险和2.6倍的MACCE风险.
- 动脉移植并没有改善DD患者的存活率;EuroSCORE II显示长期存活的差异差.
结论:
- 透析依赖是CABG后不良结果的强有力的独立预测因素.
- 目前的风险分层模型,如EuroSCORE II,对于预测DD患者的长期存活率是不充分的.
- 对于这种高风险人群,急需开发透析特异性风险模型和量身定制的手术策略.

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...

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,...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
