本文168例受检者做了活动平板心电图运动试验(EET).综合ST与非ST变化作为分析参数,参照同时进行的~(99m)TC-MIBI心肌断层显像结果,探讨了EET多参数分析在冠心病中的诊断价值.结果表明:随着EET上反映心肌缺血信息量的增多,诊断准确性也相应提高.单项ST指标诊断敏感性、特异性与阳性预测率分别为64.3% 、73.6%和84.9%;三项指标积分法分别为61.7%、90.6%与93.4%;而六项指标积分法分别达78.3%、90.6%和94.6%.以六项指标积分法诊断准确性最高,与单项ST指标相比其阳性预测值差异有显著意义(P<0.01).
In this study, 168 patients underwent active treadmill exercise test (EET) .Total ST and non-ST changes were taken as the analysis parameters, and the simultaneous (99m) TC-MIBI myocardial perfusion imaging results were used to investigate the EET multi-parameter analysis In diagnosis of coronary heart disease.The results showed that with the increase of information on myocardial ischemia on EET, the diagnostic accuracy also increased accordingly.The sensitivity, specificity and positive predictive value of single ST were 64.3%, 73.6 % And 84.9%, respectively.The integral of the three indicators were 61.7%, 90.6% and 93.4% respectively, while the six indicators were 78.3%, 90.6% and 94.6% There was significant difference between single ST index and its positive predictive value (P <0.01).
