摘　　要：目的探讨白细胞计数在急性肺栓塞患者入院早期危险分层中的作用。方法回顾性分析78例急性肺栓塞患者的临床资料，其中高危组13例、中危组27例、低危组38例，白细胞升高组23例、白细胞正常组55例。结果白细胞计数从高危、中危到低危患者呈递减趋势，高危组白细胞计数高于中危组及低危组，高危患者白细胞升高者达53．85％，中危患者37．04％，而低危患者15．79％。白细胞升高组肌钙蛋白I阳性率、BNP、PESI≥1分比例及院内死亡发生率均高于白细胞正常组（均P〈0．05）。结论白细胞计数在急性肺栓塞患者入院早期危险分层中有一定的临床价值。Objective To assess the application of white blood cell counts for early risk stratification in acute pulmonary embolism patients. Methods Clinical data were collected from 78 patients with acute pulmonary embolism and retrospectively analyzed. These patients were divided into a high-risk group （13/78）, an intermediate-risk group （27/78）, and a low-risk group （38/78）. Among them were 23 patients who reported increased white blood cell counts, and 55 patients with normal white blood cell counts. Results High-risk patients produced higher white blood cell counts （53.85%） than those at intermediate （37.04%） and low risks （15.79%）. Patients with increased white cell counts presented a positive rate of troponin I, BNP, the percentage of patients with （1 sPESI and in-hospital mortality which were all markedly higher than those in normal white blood cell counts group （P 〈0.05）. Conclusion White blood cell counts are useful for early risk stratification in acute pulmonary embolism patients.
