平板运动试验对慢性闭塞性病变患者介入治疗的评价

目的探讨平板运动试验(TET)预测慢性冠状动脉闭塞性病变(CTO)患者介入治疗的价值。方法选择冠状动脉造影确诊单支血管CTO病变患者247例,于介入治疗前行TET检查,PCI后一年随访心绞痛分级、心功能分级、超声心动图(包括左室射血分数和左室舒张末期直径)的变化,及主要不良心血管事件。结果临床随访一年,A组与B组,B组与C组在心绞痛分级、心功能分级、左室射血分数、左室舒张末期直径比较差异有统计学意义(P<0.05)。结论 TET能有效评价CTO患者PCI疗效。

Evaluation of treadmill exercise test on the patients of percutanenous coronary intervention to chronic total occlusion

Objective To evaluate the value of treadmill exercise test on the patients of percutanenous coronary intervention to CTO.Methods 247 cases of CTO patients diagnosed by coronary angiography were selected in this evaluation.Before intervention,they were examined by using TET.The patients were followed for one year after PCI in angina pectoris by applying CCs standard,cardiac function by applying NYHA Standard,left ventricular ejection fractions,left ventricular end diastolic diameter and MACE.Results All the patients were followed for one year.Compaired group A with group B,we can see that the differences in the grading of the angina pectoris and the cardiac function by applying NYHA Standard and the left ventricular ejection fractions and the left ventricular end diastolic diameter were significant（P〈0.05）.The same was between in group C and in group B.Conclusion TET can effectively evaluate the therapeutic effect of PCI for the patients with CTO.
