摘要 目的研究老年冠心病患者D-二聚体水平与冠状动脉严重程度的关系,探讨其预测不良心血管事件(MACE)的作用。方法入选冠状动脉造影诊断老年冠心病患者130例,记录所有患者的临床资料,包括血浆D-二聚体水平、左心室射血分数、心血管危险因素等。根据D-二聚体水平分为3组[A组(0.364±0.080)mg/L,56例;B组(0.651±0.134)mg/L,57例;C组(1.426±0.388)mg/L,17例],采用Gensini评分判断血管狭窄程度。患者平均随访(17.469±5.024)个月,记录主要MACE,按有无发生MACE分为两组(MACE组36例;非MACE组94例)。分析D-二聚体水平与老年冠心病其他危险因素、Gensini评分、MACE发生率的关系。结果 B、C组Gensini评分较A组均明显升高(P<0.05);B组左心室射血分数显著较A组低(P<0.05);MACE组较非MACE组D-二聚体水平和Gensin评分明显升高(P<0.05);多因素COX回归分析D-二聚体是老年冠心病患者MACE发生的独立预测因素[RR=1.124,95%CI(1.043~1.211),P=0.002]。Kaplan-Meier生存曲线显示高D-二聚体水平组患者MACE发生率明显升高(Log Rankχ~2=13.083,P=0.001)。结论老年冠心病患者血浆D-二聚体水平与冠状动脉病变严重程度及预后密切相关。
