摘要 目的探讨红细胞体积分布宽度(RDW)对急性心肌梗死(AMI)病人住院期间发生心脏事件的预测价值。方法选取2019年1月—2020年3月在忻州市人民医院心内科住院的AMI病人215例作为AMI组,记录其住院期间心脏事件发生情况,选取同期200名健康体检者作为对照组,观察两组RDW值,用受试者工作特征(ROC)曲线评价RDW值与急性心肌梗死(AMI)病人住院期间发生心脏事件的预测价值,并寻找最佳预测截断值。将AMI组病人根据RDW的cut-off值13.55%进行分组,≥13.55%为高RDW组(97例),<13.55%为低RDW组(118例),比较两组心脏事件发生率。结果AMI组RDW值明显高于对照组,差异有统计学意义(P<0.01),RDW的曲线下面积(AUC)为0.747,cut-off值为13.55%,预测急性心肌梗死病人发生心脏事件的灵敏度为74.5%,特异度为65.0%,高RDW组心脏事件发生率为46.39%(45/97),明显高于低RDW组的8.47%(10/118),差异有统计学意义(χ^2=40.205,P<0.05)。结论RDW对预测AMI病人住院期间心脏事件的发生有一定的临床应用价值。
