目的探讨急诊疑似急性肺动脉栓塞(APE)诊断中Wells评分应用价值。方法回顾性分析该院近期收治急诊疑似APE患者76例临床资料,依据Wells评分分为低度、中度及高度可疑组,比较Wells评分单用及与D-二聚体检测联用于不同组APE发病率和诊断假阳性率。结果三组患者APE发病率和诊断假阳性率比较差异有统计学意义(P<0.05);低度可疑组患者二种方法联用于APE诊断假阳性率显著低于Wells评分单用(P<0.05)。结论 Wells评分用于急诊疑似APE诊断具有操作简便,预测准确度高等优势,而联合D-二聚体检测有助于降低诊断假阳性率。
Objective To investigate the value of Wells score in the diagnosis of acute suspected pulmonary embolism (APE). Methods The clinical data of 76 patients with suspected APE admitted to our hospital recently were retrospectively analyzed. According to Wells score, the patients were divided into low, medium and high suspicious groups. Wells score was compared with Wells score alone and with D-dimer test in different groups APE incidence and diagnostic false positive rate. Results There was significant difference in the incidence of APE and the false positive rate of diagnosis between the three groups (P <0.05). The false positive rate of APE combined with two methods in patients with low suspicious group was significantly lower than Wells score (P < 0.05). Conclusion The Wells score has the advantages of simple operation and high predictive accuracy in the diagnosis of suspected APE. Combined D-dimer test can reduce the diagnostic false positive rate.
