运动平板实验联合DCG检查对冠状动脉粥样硬化性心脏病患者诊断符合率的影响

The effect of treadmill exercise test combined with DCG examination on the diagnostic coincidence rate of patients with coronary atherosclerotic heart disease

目的探究运动平板实验(TET)联合24 h动态心电图(DCG)检查对冠状动脉粥样硬化性心脏病(CHD)患者诊断符合率的影响。方法选取本院2016年2月至2019年3月疑诊CHD患者60例,均行TET、DCG、冠状动脉造影(CAG)检查,以CAG结果为金标准。统计CAG检查结果,比较CHD及非CHD患者rSBPR≥1.0者占比,TET、DCG单独及联合诊断CHD诊断价值,TET、DCG单独及并联对病变血管诊断敏感度。结果 60例疑诊CHD患者中,35例CHD患者,25例非CHD患者;CHD患者rSBPR≥1.0者占比高于非CHD患者(P<0.05);TET、DCG单独及联合诊断CHD符合率比较差异无统计学意义;TET、DCG并联敏感度高于二者单独诊断(P<0.05);TET、DCG串联特异度高于二者单独诊断(P<0.05);TET、DCG单独及并联对病变血管诊断敏感度比较差异无统计学意义。结论 TET联合DCG检查应用于CHD患者,可有效提高诊断价值,值得临床推广应用。

Objective To explore the effect of treadmill exercise test(TET)combined with 24 h dynamic electrocardiogram(DCG)on the diagnostic coincidence rate of patients with coronary atherosclerotic heart disease(CHD).Methods A total of 60 patients with suspected CHD in our hospital from February 2016 to March 2019 were selected for TET,DCG,and coronary angiography(CAG)examinations,and the CAG results were the gold standard.Statistic CAG examination results,compare the proportion of CHD and non-CHD patients with rSBPR≥1.0,TET,DCG alone and combined diagnosis of CHD diagnostic value,TET,DCG alone and combined diagnosis sensitivity of diseased blood vessels.Results Among 60 suspected CHD patients,35 were CHD patients and 25 were non-CHD patients.THE proportion of CHD patients with rSBPR≥1.0 was higher than that of non-CHD patients(P<0.05).There was no significant difference in the coincidence rate of TET and DCG alone and combined diagnosis of CHD.The parallel sensitivity of TET and DCG was higher than the two alone diagnosis(P<0.05).There was no significant difference in the sensitivity of TET and DCG alone and in parallel to the diagnosis of diseased blood vessels.Conclusion TET combined with DCG examination for CHD patients can effectively improve the diagnostic value and is worthy of clinical application.
