急诊疑似急性肺动脉栓塞诊断中Wells评分应用价值探讨

CLINICAL APPLICATION VALUE INVESTIGATION OF WELLS SCORES ON DIAGNOSIS OF SUSPECTED ACUTE APE IN EMERGENCY

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 clinical application value investigation of Wells scores on diagnosis of suspected acute APE in emergency. Methods Clinical data of 76 patients with suspected acute APE in emergency were retrospectively analyzed and divided into 3 group including low degree suspected group, me dium degree suspected group and high degree suspected group according to Wells scores; and the incidence rate of APE and false positive rate of diagnosis in different groups by Wells score used alone and combined with Ddimer detection were compared. Results There were significant differences in incidence rate of APE and false positive rate of diagnosis among 3 groups（P〈0.05）. The false positive rate of diagnosis in low degree suspected group by two method combined diagnosis was significantly lower than Wells score used alone（P〈0.05）. Conclusion Wells scores on diagnosis of suspected acute APE in emergency have advantages including simple operation and high prediction accuracy; Wells scores combined with D- dimer detection on diagnosis of suspected acute APE is helpful to lower false positive rate of diagnosis.
