Abstract

Purpose: Low-risk pulmonary thromboembolism (PTE) outpatient management has been described recently. The blood neutrophil/lymphocyte ratio (NLR) has been shown to be a useful marker of cardiovascular disease and an independent predictor of cardiac mortality. The predictive value of NLR in predicting mortality of low-risk PTE was evaluated in this study. Materials and Methods: The total of 168 patients with definite pulmonary embolism diagnosed by computed tomography angiography whose on-admission simplified Pulmonary Embolism Severity Index (PESI) score was zero enrolled in this study. The survival rate of patients according to their NLR was evaluated. Results: During 12 months' follow-up period, eight patients (4.7%) died. None of the patients with an NLR of <3.2 died during the follow-up. The median values of NLR in the nonsurvivor and survivor groups were 9.2 ± 3.03 (2–29.5) and 4.69 ± 0.43 (0.8–24.5), respectively. NLR values were significantly higher in nonsurvivors compared to survivors (P = 0.043). Conclusion: This study suggests that patients with zero PESI score and NLR <3.2 could be managed patiently with good results.
中性粒细胞与淋巴细胞比值与低危急性肺栓塞的门诊管理
目的:低风险肺血栓栓塞(PTE)的门诊管理已被描述最近。血液中性粒细胞/淋巴细胞比率(NLR)已被证明是心血管疾病的有用标志和心脏死亡率的独立预测因子。本研究评估NLR对低危PTE死亡率的预测价值。材料与方法:本研究共纳入168例经计算机断层血管造影诊断为明确肺栓塞且入院时简化肺栓塞严重指数(PESI)评分为零的患者。根据NLR评估患者的生存率。结果:随访12个月,死亡8例(4.7%)。NLR <3.2的患者在随访期间均无死亡。非存活组和存活组NLR的中位值分别为9.2±3.03(2-29.5)和4.69±0.43(0.8-24.5)。非幸存者的NLR值明显高于幸存者(P = 0.043)。结论:本研究提示PESI评分为零、NLR <3.2的患者可以耐心治疗,效果良好。
