摘要
目的探讨脑源性神经营养因子(BDNF)在冠心病患者血清中的表达状况及临床意义。方法 38例健康对照者及87例冠心病患者纳入研究。根据临床资料将患者分为稳定型心绞痛组(SAP,n=42)与不稳定型心绞痛组(UAP,n=45);根据冠脉造影结果将患者分为轻度狭窄组(n=12)、中度狭窄组(n=20)与重度狭窄组(n=13)。ELISA法检测所有被研究者的血清BDNF水平,并计算与冠脉狭窄的相关度。结果 SAP组与对照组血清BDNF水平比较差异无统计学意义(P>0.05),但在UAP组显著升高(P<0.01);UAP组血清BDNF水平随冠脉狭窄程度的加重而升高,呈显著正相关(r=0.735);亚组分析,血清BDNF水平与轻、中、重3组相关值分别为0.618,0.742,0.826。结论 BDNF在冠心病患者中显著上升,尤其是在不稳定型心绞痛患者中;BDNF可以作为冠脉狭窄的重要预测指标。
