概括

对于八十多岁的人来说,在冠状动脉旁路移植 (CABG) 中使用内胸动脉 (ITA) 并没有改善6年后的结果. 仅进行沙芬静脉移植 (SVG) 的策略显示了类似的主要心脏不良事件和死亡率.

科学领域:

心血管外科心血管外科
老年心脏病学老年心脏病学
医疗保健服务研究医疗服务研究

背景情况:

内胸动脉 (ITA) 的使用是冠状动脉旁路移植 (CABG) 质量的基准.
它在接受CABG的八十岁以上患者 (80岁及以上的患者) 的有效性尚未得到充分证实.
这项研究评估了中期结果,比较了老年人群中的ITA加沙发静脉移植 (SVG) 与仅SVG的结果.

研究的目的:

为了比较中期主要心脏不良事件 (MACE) 和接受CABG的80岁以上人群的全因死亡率.
评估内部胸动脉 (ITA) 在当代老年人CABG实践中的使用价值.
在八十多岁的患者中为CABG提供质量指标.

主要方法:

来自美国医疗保险数据库的13,925名八十几岁的人进行了回顾性分析,他们接受了孤立的,可选的CABG,并进行了2-4个移植 (2015-2022年).
12,280名接受ITA+SVG治疗的患者和1,105名仅接受SVG治疗的患者之间的比较.
倾向性得分匹配用于比较6年无MACE (死亡,心肌梗塞,重复血管) 和全因死亡率.

主要成果:

倾向匹配创造了1,101对可比的八十岁的夫妇.
六年免受MACE的影响是相似的:ITA+SVG的49.7%,仅SVG的48% (调整HR:0.92;p=0.23).
六年全因死亡率没有显著差异:ITA+SVG的54.8%,仅SVG的52.7% (调整HR:0.90;p=0.19).

结论:

在接受选择性多血管CABG的80多岁人群中,使用内胸动脉 (ITA) 与改善6年MACE或死亡率无关.
目前基于ITA的质量指标可能需要对八十岁的CABG患者进行重新评估.
只有SVG的策略似乎在这个特定的患者群体中提供了可比的中期结果.

关键词:

使用内胸动脉使用内胸动脉.八分之一生的人.作为一种普遍的质量指标,质量指标是普遍的.

Coronary Artery Disease V: Interprofessional Care

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
