摘要
目的了解运动平板试验(TET)在评估冠状动脉支架术后支架内再狭窄(ISR)的价值。方法81例PCI术患者均在术后进行了TET及冠脉造影(CAG)检查,以CAG检查结果作为金指标,分析计算TET对于诊断ISR的敏感性、特异性、阳性预测率、阴性预测率,及Kappa值。结果TET诊断ISR的敏感性为52.9%、特异性为88.4%、阳性预测率为47.4%、阴性预测率为87.1%;在诊断单支病变的ISR的敏感性为66.7%、特异性为96.2%、阳性预测率为80%、阴性预测率为92.6%,Kappa值为0.671。结论TET对于评估ISR有一定的临床意义,尤其是在单支病变PCI术后的患者中,TET诊断ISR与CAG检查有较高的一致性,对于临床诊治有指导作用。
Objective To assess the value of treadmill testing to evaluate in - stent restenosis on patients after PCI (pereutaneous transluminal coronary intervention). Methods Eight-one patients who underwent successful PCI were performed with treadmill testing and CAG( coronary artery angiography). With the result of CAG as the "golden standard", analyze the sensitivity , specificity, the rate of positive prognosis , the rate of negative prognosis and data Kappa of the treadmill testing for detecting in - stent restenosis. Results The sensitivity , specificity, rate of positive prognosis and rate of negative prognosis were 52.9% ,88.4% ,47% ,87.1% respectively. Especially in the single - vessel group, they were 66.7% ,96% ,80% ,92.6% respectively and the data Kappa was 0. 671. Conclusion In the patients who underwent PCI , the treadmill testing could be useful to detect the in - stent restenosis . In single - vessel group , the result of the treadmill testing was concordant with CAG, The treadmill testing can be used in clinic to guide the diagnosis and treatment.
