【摘要】 目的:探讨胸痛患者血中D-二聚体(D-dimer)结果及临床意义。方法:测定197例急诊内科胸痛患者血D-二聚体结果,分析D-二聚体在恶性胸痛急性冠脉综合征(ACS)、肺栓塞(PTE)及主动脉夹层中特异性及敏感性。结果:胸痛患者D-二聚体阳性率为26.39%;恶性胸痛特异性82.69%,敏感性100%。结论:D-二聚体检查可作为急性恶性胸痛排查标准;排除非恶性胸痛,避免漏诊恶性胸痛。更多还原

【Abstract】 Objective:To discuss the result and clinical meaning of D-dimer in the patients with chest pain.Methods:D-dimer of 197 internal patients with cheest pain in emergency room were tested,and analysed on the specificity and the sensitivity of the D-dimer in malignant chest pain,acute coronary syndrome,pulmonary thromboembolism and aortic dissection.Results:D-dimer positive rate were 26.39% in patients with chest pain.In malignant chest pain the specificity were 82.69%,the sensitivity were 100%.Conclusion:D-dimer examination can be a criterion of eliminating acute malignant chest pain.Eliminate non-malignant chest pain,so as to avoid to misdiagnosis of patient with malignant chest pain.更多还原
