摘要目的分析24 h动态心电图结合平板运动试验诊断隐匿型冠心病(latent coronary heart disease,LCHD)的临床价值。方法选择2015年1月至2018年2月在我院就诊的经冠脉造影确诊为LCHD的患者100例,分别进行24 h动态心电图、平板运动试验以及冠脉造影检查并分析临床诊断结果。结果24 h动态心电图与平板运动试验的敏感性(82.81%vs.82.54%)、特异性(61.11%vs.67.56%)、准确率(75.00%vs.77.00%)以及阴阳性预测值(66.67%vs.69.44%,79.10%vs.81.25%)比较,差异无统计学意义(P>0.05)。动态心电图结合平板运动试验的串联法的特异性(91.89%)、阳性预测值(94.23%)均明显高于单项检查方法(P<0.05);而并联法的敏感性(95.23%)、阴性预测值(88.00%)均明显高于单项检查方法(P<0.05)。结论动态心电图结合平板运动试验的串联法与并联法对LCHD的临床诊断价值明显高于单项检查,可以有效地提高诊断的准确率。 Objective To analyze the clinical value of 24-hour ambulatory electrocardiography(AECG)combined with treadmill exercise test(TET)in diagnosing latent coronary heart disease(LCHD).Methods We selected 100 patients definitely diagnosed with LCHD by coronary angiography(CAG)in our hospital from January 2015 to February 2018.The clinical diagnosis results of 24-hour AECG,TET and CAG were analyzed,respectively.Results Between 24-hour AECG and TET,the sensitivity(82.81%vs.82.54%),specificity(61.11%vs.67.56%),accuracy(75.00%vs.77.00%),and negative and positive predictive values(66.67%vs.69.44%,79.10%vs.81.25%)did not vary significantly(P>0.05).The specificity(91.89%)and positive predictive value(94.23%)of the tandem method(AECG combined with TET)were higher than either of the two methods(P<0.05)while the sensitivity(95.23%)and negative predictive value(88.00%)of the parallel method were also significantly higher(P<0.05).Conclusion The tandem and parallel methods of AECG combined with TET are obviously more valuable than single examination in the diagnosis of LCHD.They can effectively improve the diagnostic accuracy.
