目的:探讨肺栓塞严重指数(PESI)对急性肺栓塞(PE)的预测价值。方法:利用PESI对6家医院2005年01月～2009年12月期间住院PE患者30天内的预后转归进行回顾性分析。结果:共收集PE患者185例,30d死亡率为11.9%,Ⅰ级0%、Ⅱ级2.4%、Ⅲ级6.5%、Ⅳ级15%、Ⅴ级22.5%,随PESI危险级别上升而显著升高(P<0.001)。PESI预测死亡率准确度显示敏感性及阴性预测值均高。结论:利用PESI对PE进行危险分层,可较准确地判断PE预后,进而指导临床早期干预,改善预后。
Objective: To investigate the predictive value of pulmonary embolism severity index (PESI) in acute pulmonary embolism (PE). Methods: PESI was used to analyze the prognosis of hospitalized patients with PE within 6 days from January 2005 to December 2009 in 6 hospitals. Results: A total of 185 PE patients were collected. The mortality rate at 30d was 11.9%, grade Ⅰ 0%, grade Ⅱ 2.4%, grade Ⅲ 6.5%, grade Ⅳ 15%, grade Ⅴ 22.5%, significantly increased with the increase of PESI risk level (P <0.001). The accuracy of PESI-predicted mortality shows both high sensitivity and negative predictive value. Conclusion: PESI risk stratification of PE can be more accurately determine the prognosis of PE, and then guide the clinical early intervention to improve the prognosis.
