目的 分析急性肺栓塞（APE）患者肺栓塞严重程度指数（PESI）与血清钠水平的病情评估价值和关系.方法 回顾性分析经CT肺动脉造影确诊的APE患者临床资料.结果 22例患者入选,PESI低危组均为低危APE,PESI中、高危组的中、高危APE发生率为66.67％,与PESI低危组比较差异显著;共6（27.27％）例APE患者出现低钠血症,其中2（33.33％）例在诊断一月内死亡,低钠血症组和非低钠血症组中、高危APE发生率比较无显著性差异;APE患者血清钠水平与PESI相关系数为-0.318（P =0.149）.结论 PESI而非低钠血症对APE病情严重性具有指导价值,合并低钠血症的APE患者一月内死亡率高.

英文摘要：

Objective To analyze the value and relation of pulmonary embolism severity index （PESI） and serum sodium on the severity of patients with acute pulmonary embolism （APE）.Methods The clinical data of patients with APE diagnosed by CT pulmonary angiogram were collected by a retrospective analysis.Results The data of 22 patients with APE were confirmed.In the low-risk group of PESI classification,all patients were low-risk APE,The intermediate and high-risk group of PESI classification,the intermediate and high-risk pulmonary embolism accounted for 66.67％.there was significant difference between the low-risk group and the intermediate and high-risk group of PESI classification in the incidence rate of intermediate and high-risk pulmonary embolism.Hyponatremia were present in 6 cases with APE （27.27％）,of which two （33.33％） patients died in one month after the diagnosis of APE.Compared with the non-hyponatremia group,the incidence rate of intermediate and high-risk pulmonary embolism was not significantly different in the hyponatremia group.The correlation coefficient of serum sodium and PESI of APE was-0.318 （P =0.149）.Conclusions PESI rather than the hyponatremia could evaluate the severity of APE.The high death rate in one month after the diagnosis is present in APE patients with hyponatremia.
