摘要 目的探讨肿瘤坏死因子-α(TNF-α)与慢性心力衰竭(CHF)患者心功能之间的关系。方法选取2011年8月至2014年11月在该院心血管内科住院的CHF患者80例作为观察组,依据纽约心脏病学会分型标准,将其分为心功能Ⅲ、Ⅳ级组,各40例。另选取同期健康体检人群40例作为对照组。所有受试者均清晨空腹采集肘静脉血,检测血清TNF-α水平,应用心脏多普勒超声测定左心室射血分数(LVEF)。比较各组血清TNF-α水平与LVEF变化,并应用Pearson′s线性相关分析TNF-α、LVEF指标间的对应关系。结果观察组患者血清TNF-α水平较对照组明显升高,而LVEF水平较对照组降低,差异均有统计学意义(P<0.05)。心功能Ⅲ级组患者血清TNF-α水平明显低于心功能Ⅳ组,而LVEF明显高于心功能Ⅳ组,差异均有统计学意义(P<0.05)。血清TNF-α水平与LVEF呈负相关(r=-0.509,P<0.05)。结论CHF患者外周血中TNF-α水平与CHF严重程度有关,对于CHF的诊断、评估预后及指导治疗有一定意义。
