【摘要】:目的探讨N末端B型利钠肽原(NT-pro BNP)联合冠状动脉钙化总积分(TCS)对老年稳定性冠心病(SCAD)患者预后风险评估的价值。方法选取2013年3月—2016年1月在安徽医科大学附属省立医院老年心内科住院治疗的老年SCAD患者264例,根据随访期(2~34个月)内是否发生主要不良心血管事件(MACE)分为非MACE组(n=151)和MACE组(n=113)。采用德国Roche Elecsys 2010全自动免疫分析仪及Roche试剂盒检测血浆NT-pro BNP水平;采用美国通用电器公司(GE)的64排128层螺旋CT对患者进行冠状动脉CT平扫,采集数据后将扫描得到的图像传到工作站,利用自带的Smart score软件计算TCS。运用统计学分析将两种指标联合建立综合预测模型实现对老年SCAD患者发生MACE的评估。结果两组性别、年龄、BMI、吸烟史、高血压病史、糖尿病病史、血脂异常史间差异均无统计学意义(P0.05)。MACE组NT-pro BNP、TCS均高于非MACE组,差异有统计学意义(P0.05)。构建Logistic回归模型:Logit(P)=-2.602+0.001NT-pro BNP+0.010TCS,得到新联合指标Logit(P)。新联合指标预测老年SCAD患者发生MACE的受试者工作特征(ROC)曲线下面积(AUC)为0.891〔95%CI(0.847,0.926),P0.01〕,灵敏度和特异度分别为0.788、0.848;NT-pro BNP预测老年SCAD患者发生MACE的AUC为0.770〔95%CI(0.715,0.820),P0.01〕,灵敏度和特异度分别为0.549、0.808;TCS预测老年SCAD患者发生MACE的AUC为0.833〔95%CI(0.782,0.876),P0.01〕,灵敏度和特异度分别为0.779、0.755。新联合指标与NT-pro BNP、TCS预测老年SCAD患者发生MACE的AUC比较,差异均有统计学意义(Z值分别为4.83、2.63,P0.01);NT-pro BNP与TCS预测老年SCAD患者发生MACE的AUC比较,差异无统计学意义(Z=1.56,P=0.12)。结论NT-pro BNP联合TCS对老年SCAD患者预后风险评估的价值高于任一单个指标,为老年SCAD患者不良预后早期预测提供更可靠的方法。
