本试验对冠心病、可疑冠心病和正常对照组各21例,分别进行潘生丁食管心房调搏负荷超声心动图观测,潘生丁食管心房调搏负荷试验和潘生丁试验的同步对比研究。并对可疑冠心病者进行了6～12个月的随访。结果表明:潘生丁食管心房调搏负荷超声心动图对冠心病诊断的敏感性和特异性均为95.2％,其价值显著优于潘生丁试验。提示此检测对某些诊断困难的冠心病患者是有价值的。
In this study, coronary heart disease, suspicious coronary heart disease and normal control group of 21 cases, respectively, dipyridamole esophageal atrial pacing load echocardiography, dipyridamole esophageal atrial pacing load test and dipyridamole test comparative study. Suspected coronary heart disease patients were followed up for 6 to 12 months. The results showed that the sensitivity and specificity of dipyridamole esophageal atrial pacing load echocardiography in the diagnosis of coronary heart disease were 95.2%, its value was significantly better than the dipyridamole test. Suggesting that this test is valuable for some patients with coronary heart disease who have difficulty in diagnosis.
