【摘要】 目的:评价平板运动试验(TET)对决定冠脉临界病变患者治疗方案的指导意义。方法:选择2004年1月至2007年4月在我院介入中心行冠状动脉造影(CAG)显示血管狭窄程度50%～70%的患者共115例,以上患者在CAG术后2～3d内行TET,再将TET结果阴性者分为A组(50例),TET阳性可疑患者分为B组(29例),TET结果阳性者分为C组(36例),最后比较三组中介入治疗及药物治疗比例,并对治疗效果随访1月～3年零4个月,记录主要不良心血管事件。结果:A组50例,其中46例采取药物治疗,4例予以介入治疗(PCI),B组29例,24例药物治疗,5例给予介入治疗;C组36例,介入治疗23例,药物治疗13例;C组介入治疗显著多于A、B两组(P<0.005),A、B两组药物治疗率显著多于C组(P<0.005),两种治疗率A、B组间无显著差异。结论:平板运动试验能客观地反应心肌缺血状况,且方法简便易行,对于有冠脉临界病变患者治疗有较大指导意义。更多还原

【Abstract】 Objective:To evaluate direction value of treadmill exercise testing(TET)on determination therapeutic scheme of patient with critical pathological changes of coronary artery.Methods:A total of 115 patients with 50%~70% angiostenosis by CAG were studied.The TET were choose 2~3 days after coronary angiography(CAG).The patients who have negative,probable positive or positive TET results were diveded into group A(50 cases),B(29 cases)or C(36 cases)respectively.Results:The rate of treat by PCI of group C was much higher than that of group A or B(P<0.005).The rate of treat by drugs in group A or B was much higher than that of group C(P<0.005).The rate of treat by PCI and drugs was no significant difference between group A and group B(P>0.05).Conclusion:The doctor would chose to do TET for the patients with critical pathological changes of coronary artery before treat,because TET has comparatively large directions meaning in clinic treatment.更多还原
