目的探究IMA检测对急性胸痛患者的鉴别诊断价值,以利于临床对心源性胸痛的早期诊断。方法通过检测88例以胸痛症状来我院急诊患者的IMA水平,根据患者最终确定的临床诊断,计算IMA预测心源性胸痛的敏感性和特异性,由此分析IMA对于急性胸痛患者鉴别诊断的意义。结果研究发现所有88例入选患者中,心源性胸痛54例,IMA均值高达(99.56±18.67)U/ml,非心源性胸痛患者34例,IMA均值为(49.35±11.22)U/ml。两者差异有统计学意义(P<0.05)。IMA检测的灵敏度、特异度和阴性预测价值均较高,分别为94.4%、79.4%和90%。结论急性胸痛患者IMA的检测可以高效率地鉴别心源性及非心源性胸痛,尤其灵敏度及阴性预测值较高,能显著减少心源性胸痛患者的漏诊,降低由此而产生的医疗风险。
Objective To explore the value of IMA detection in the differential diagnosis of patients with acute chest pain in order to facilitate the clinical diagnosis of cardiogenic chest pain in the early stage. Methods 88 cases of chest pain in our hospital emergency patients by IMA levels, based on the patient’s final diagnosis of the diagnosis of IMA to predict the sensitivity and specificity of cardiac chest pain, thus analyzing the differential diagnosis of acute chest pain in patients with IMA significance. Results Of the 88 patients enrolled, 54 patients had cardiogenic chest pain with an average IMA value of 99.56 ± 18.67 U / ml, 34 patients with non-cardiac chest pain and an average IMA value of (49.35 ± 11.22) U / ml. The difference was statistically significant (P <0.05). Sensitivity, specificity and negative predictive value of IMA were higher, 94.4%, 79.4% and 90% respectively. Conclusion The detection of IMA in patients with acute chest pain can identify cardiogenic and non-cardiac chest pain with high efficiency. Especially, the sensitivity and negative predictive value are higher, which can significantly reduce the missed diagnosis of cardiac chest pain and reduce the medical risk .
