摘要
目的研究平板运动试验(treadmill exercise test,TET)对冠心病诊断及预后风险评估的临床价值。方法随机选取2012年3月至2014年3月收入我院的疑似冠心病患者206例。入院2周内,所有患者均行冠脉造影(coronary angiography,CAG)及TET检查;以CAG检查结果作为诊断标准,评价TET结果的准确性。结果 TET检查诊断冠心病的符合率为84.1%、特异度为73.2%、灵敏度为89.7%、诊断准确率为62.4%;1支、2支和3支病变的阳性率分别为79.3%、83.1%和100%,对三组进行两两比较,差异有统计学意义(P<0.05)。结论 TET为无创性检查,诊断符合率、特异度和灵敏度较高,值得在冠心病临床诊断中推广运用。
Objective To investigate the clinical value of treadmill exercise test（ TET） in the diagnosis and prognosis risk evaluation of coronary heart disease. Methods A total of 206 patients with suspected coronary heart disease were selected who had been admitted in our hospital from March 2012 to March 2014. All the enrolled cases underwent examinations of coronary angiography（ CAG） and TET within two weeks after admission. Taking CAG results as diagnostic criteria,we evaluated the accuracy of TET results. Result In the diagnosis of coronary heart disease by TET,the diagnostic accordance rate was 84. 1%,the specificity was 73. 2%,the sensitivity was 89. 7%,and the diagnostic accuracy was 62. 4%. The positive rate was 79. 3%,83. 1% and 100% respectively for patients separately with lesions in single vessel,two and three vessels; pairwise comparison among the three groups indicated that the differences were statistically significant（ P〈0. 05）. Conclusion TET is a noninvasive inspection method with relatively high diagnostic accordance rate,specificity and sensitivity. It is worthy of being promoted and applied clinically.
