平板运动试验在PCI术后疗效评价中的作用

The effect of treadmill exercise testing on efficacy evaluation of post operation of percutaneous coronary iatrotechnics

目的:探讨平板运动试验在经皮冠状动脉治疗术(PCI)后疗效评价中的作用。方法:选择行PCI术的患者36例,所有患者于PCI术前均已经冠状动脉造影检查确认其病变冠脉管腔狭窄或闭塞大于70%。分别于术前(5.0±1.9)d及术后(4.8±2.6)d行平板运动试验,比较两者的运动时间、运动做功量、最大心率及最大心率—血压乘积。结果:患者PCI术后行平板运动试验的运动时间、运动做功量、最大心率及最大心率—血压乘积均较术前明显提高。结论:PCI能够有效改善患者心功能,提高运动耐量,通过平板运动试验可有效评价PCI术后疗效。

Objective To investigate the effect of treadmill exercise testing on efficacy evaluation of post operation of percutaneous coronary iatrotechnics（PCI）.Methods 36 patients treated with PCI were chosen to be researched.According to the coronary angiography, eoronary lumen stenosis or seclusion of all patients were more than 70% before PCI.Patients were given treadmill exercise testing on pre-operation with（5.0±1.9） days and post operation with （4.8±2.6） days.Movement time,total work of movement,the maximum heart rate（HRmax） and product of heart rate-blood pressure were compared in order to evaluate the efficacy of PCI for increasing exercise tolerance and improving cardiac function.Results Post operation of PCI,movement time,total work of movement,Conclusion PCI can improve cardiac function,increase exercise tolerance,and treadmill exercise testing can evaluate the efficacy of post operation of PCI.
