摘要 目的探讨冠心病患者冠状动脉病变程度与N端脑钠肽前体(NT-proBNP)之间的关系和临床意义。方法选择100例行冠状动脉造影检查的患者作为研究对象,造影结果正常21例(对照组),造影检查明确诊断为冠心病79例,其中稳定型心绞痛21例(SAP组)、不稳定型心绞痛30例(UAP组)、急性心肌梗死28例(AMI组)。采用Gensini积分评估冠状动脉病变严重程度,同时测定NT-proBNP、肌酸激酶同工酶(CK-MB),分析患者NT-proBNP、CK-MB水平变化与冠脉造影冠状动脉病变严重程度之间的关系。结果 AMI组平均NT-proBNP水平明显高于UAP组、SAP组和对照组(P<0.05)。UAP组平均NT-proBNP水平明显高于SAP组和对照组(P<0.05),SAP组平均NT-proBNP水平高于对照组(P<0.05)。AMI组的NT-proBNP水平与CK-MB水平有明显的相关性(r=0.450,P<0.01)。冠脉造影结果闭塞组NT-proBNP水平明显高于狭窄组和无狭窄组(P<0.05)。狭窄组NT-proBNP水平高于无狭窄组(P<0.05)。NT-proBNP水平与Gensini积分有明显相关性(r=0.962,P<0.01)。结论 NT-proBNP与冠心病心肌缺血程度和冠状动脉狭窄程度呈正相关,测定NT-proBNP水平对冠心病患者的诊断、病情评估具有一定的临床意义。
