概括

血红蛋白与红细胞分布宽度比 (HRR) 是胸腔腹腔大动脉瘤 (TAAA) 患者死亡率的负预测指标. 较低的HRR值与TAAA病例的死亡风险增加有关.

科学领域:

心血管医学心血管医学
血液学血液学血液学
在瘤学瘤学.

背景情况:

在胸腔腹腔大动脉瘤 (TAAA) 患者中,血红蛋白与红细胞分布宽度比率 (HRR) 的预后意义仍然不清楚.
以前的研究已经强调了HRR在心血管和癌症疾病风险分层中的作用.

研究的目的:

调查TAAA患者HRR和死亡率之间的相关性.
评估HRR对TAAA患者预后结果的预后价值.

主要方法:

从MIMIC-IV数据库中对1,824名TAAA患者进行了回顾性分析.
使用血红蛋白 (Hb) 和红细胞分布宽度 (RDW) 的水平计算HRR.
使用后勤回归,限制立方线 (RCS),ROC曲线和决策曲线分析来评估死亡率相关性和预后价值.

主要成果:

总共有1,824名患者被分析,分层由HRR三分之一.
后勤回归表明HRR和住院死亡率之间存在显著的负相关性 (OR:0.151,95%CI:0.028-0.838).
RCS分析证实了线性相关性,ROC分析表明HRR具有显著的预测优势 (AUC:0.727).

结论:

血红蛋白与红细胞分布宽度比 (HRR) 与TAAA患者的死亡率有显著的负相关性.
HRR是该患者队列中死亡率的有价值和相对独立的预测指标.

关键词:

血红蛋白与红细胞分布宽度比 (HRR)这就是MIMIC-IV.死亡率相关性相关性预测价值的预测价值是什么胸腔腹腔大动脉动脉瘤 (TAAA) 的情况

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
