目的:探究D二聚体在急诊主动脉夹层患者中的诊断效果,为临床提供指导。方法:以我院2015年6月至2017年7月期间经血管造影确诊的45例急诊主动脉夹层患者(急诊主动脉夹层组)以及45例同期以急性胸痛为主诉的非夹层患者(对照组)作为本次研究的观察对象,对所有纳入患者均实施D二聚体检测。选择统计学软件(SPSS19.0)进行数值分析处理,对比两组患者的D二聚体水平。结果:急诊主动脉夹层组患者的D二聚体水平为(924±161)μg/L,相比对照组[(85±22)μg/L]明显更高,P<0.05;Ⅰ型组急诊主动脉夹层组患者的D二聚体水平为(1207±363)μg/L,相比Ⅱ型组、Ⅲ型组患者的D二聚体水平[(628±132)μg/L、(896±237)μg/L]明显更高,P<0.05,且Ⅱ型组、Ⅲ型组患者之间的D二聚体水平亦存在显著差异,P<0.05。结论:D二聚体在急诊主动脉夹层患者中的诊断中具有较显著的效果,值得各医院推广应用。
Objective: To investigate the diagnostic value of D-dimer in emergency patients with aortic dissection and provide guidance for clinical practice. Methods: Forty-five patients with acute aortic dissection (emergency aortic dissection group) diagnosed by angiography during our hospital from June 2015 to July 2017 and 45 non-disseminated patients (control group ) As an observational study of this study, D-dimer testing was performed on all patients included. Statistical software (SPSS 19.0) was selected for numerical analysis to compare D-dimer levels in both groups. Results: The level of D-dimer in the patients with acute aortic dissection was (924 ± 161) μg / L, which was significantly higher than that in the control group [(85 ± 22) μg / L, P <0.05) The level of D dimer in patients with aortic dissection was (1207 ± 363) μg / L, which was significantly higher than that in patients with type Ⅱ and type Ⅲ (628 ± 132 μg / L and 896 ± 237) μg / L] was significantly higher, P <0.05. There was also a significant difference in D dimers between type Ⅱ and type Ⅲ patients, P <0.05. Conclusion: D dimer has a significant effect in the diagnosis of patients with emergency aortic dissection, and is worth promoting in various hospitals.
