【摘要】 目的:探讨急性胸痛患者的D-二聚体、纤维蛋白原(fibrinogen,FIB)和纤维蛋白(原)降解产物(fibrinogen degradation product,FDP)的表达水平与急性胸痛相关疾病的关系。方法:回顾性分析2017年5月1日至2018年4月30日中南大学湘雅医院急诊科收治的主动脉夹层、肺栓塞、急性心肌梗死患者的临床资料。患者均表现为急性的胸部和/或背部疼痛,入院时均检测血浆D-二聚体,FIB和FDP,均通过CT血管造影(computed tomography angiography,CTA)和经皮冠状动脉介入治疗(percutaneous transluminal coronary intervention,PCI)确诊。比较3种疾病患者的D-二聚体,FIB和FDP的水平和阴性率。结果:共纳入234例患者,包括主动脉夹层患者95例,急性心肌梗死患者98例和肺栓塞患者41例。主动脉夹层组、急性心肌梗死组和肺栓塞组的D-二聚体阴性率依次分别为13.68%,70.41%和4.88%;FDP阴性率依次分别为24.21%,81.63%和 24.39%。主动脉夹层和肺栓塞组中D-二聚体和FDP阴性率的差异无统计学意义(均P>0.05),但心肌梗死组的D-二聚体和FDP阴性率显著高于主动脉夹层和肺栓塞组(均P<0.001)。急性心肌梗死组D-二聚体水平显著低于主动脉夹层组和肺栓塞组(均P<0.001),而主动脉夹层组与肺栓塞组之间的D-二聚体水平差异无统计学意义(P>0.05);各组患者间FIB水平差异无统计学意义(均P>0.05);急性心肌梗死组的FDP水平显著低于主动脉夹层组和肺栓塞组(均P<0.001),而主动脉夹层组与肺栓塞组之间的FDP水平差异无统计学意义(P>0.05)。结论:D-二聚体和FDP在主动脉夹层和肺栓塞导致的急性胸痛中表达水平升高,并可能作为二者初步诊断的标志物;但不适于诊断疑似急性心肌梗死。更多还原

【Abstract】 Objective: To determine the relationship among the levels of D-dimer, fibrinogen (FIB), and fibrin degradation products (FDP) in acute fatal chest pain patients.Methods: We retrospectively analyzed the patients with aortic dissection (AD), pulmonary embolism (PE) or acute myocardial infarction (AMI) from May 1, 2017 to April 30, 2018. All the patients had a chest and/or back pain. Levels of D-dimer, FIB, and FDP were examined at the time of admission, and the patients were further diagnosed by computed tomography angiography (CTA) or percutaneous transluminal coronary intervention (PCI). The levels and negative rates of D-dimer, FIB, and FDP in patients with AD, PE, and AMI were compared.Results: A total of 234 patients were enrolled, including 95 AD, 98 AMI, and 41 PE. In the AD group, the AMI group and the PE group, the negative ratios of D-dimer were 13.68%, 70.41% and 4.88%, respectively; the negative ratios of FDP were 24.21%, 81.63% and 24.39%, respectively. There was no significant difference in negative rates of D-dimer and FDP between the AD group and the PE group (all P>0.05), but negative rates of D-dimer and FDP were significantly higher in the AMI group than those in the AD group and the PE group (all P<0.001). The level of D-dimer in the AMI group was significantly lower than that in the AD group or in the PE group (both P<0.001), while there was no statistically significant difference between the AD group and the PE group (P>0.05). However, there were no significant difference in the FIB levels among 3 groups (all P>0.05). The FDP level in the AMI group was significantly lower than that in the AD group or in the PE group (both P<0.001), while there was no statistically significant difference between the AD group and the PE group (P>0.05).Conclusion: The levels of D-dimer and FDP are increased in AD and PE patients and may be as the useful biomarkers for the high-risk chest pain patients but not for AMI.更多还原
