运动平板与食道调搏心脏负荷试验诊断冠心病的临床应用

Clinical application of treadmill exercise test and transesophageal atrial pacing in coronary heart disease

目的:评价运动平板试验与食道调搏心脏负荷试验对冠心病的诊断价值。方法:我院对临床诊断冠心病组186例及临床健康对照组178例进行食管调搏负荷试验,并同期进行运动平板负荷试验作对照。结果:冠心病组食道调博心脏负荷试验的敏感性、特异性分别为86.3%及81.6%,运动平板负荷试验的敏感性及特异性分别为85.3%、78.9%,二者联合则敏感性、特异性分别为98.9%及98.8%。结论:运动平板与食道调搏心脏负荷试验具有无创、安全、简便、有效的特点,投入少、费用低、容易掌握,二者联合诊断冠心病则可明显提高敏感性和准确性,因此适合在基层医院推广。

Objective： The relation of the changes of treadmill exercise test （TET） and transesophageal atrial pacing（TEAP） with the region of coronary artery disease was investigated. Methods：TET and TEAP were done for 186 coronary heart disease group patients and 178 contrast group patients. Results：The region of coronary artery disease was investigated.The trial sensitivity of TEAP was 86.3%, the particularity of TEAP was 81.6%, the trial sensitivity of TET was 85.3% the particularity of TET was 78.9%, two consociation then sensitivity, particularity distinguish were 98.9% and 98.8%. Conclusion：Clinical application of TET and TEAP in coronary heart disease, they are non-invasion, safe, simple and effective, low expenses, easily control. Two consociation diagnosis for the coronary can obviously raise sensitivity and accuracy, so it is suitable to expand in the grass-roots hospital.
