We studied 35 patients (4 females and 31 males) suffering from acute myocardial infarction (AMI) using ergometric tests (ET), ecostress test with Dobutamin (ESD) and coronary angiography within 20 days of the onset of symptoms 5.7% of patients did not show significant coronary lesions. ET was positive in 50% of cases in this group 31.4% of patients were diagnosed with monovessel coronary disease and ET and ESD were positive for residual ischemia in 33.3% of this group. The majority of patients (42.8%) suffered from bivessel coronary disease and ET and ESD were positive for residual ischemia in 45.4% and 53.8% respectively in this group. 20% of patients presented tri-vessel coronary disease and in this group the majority of patients were positive both for ET (83.8%) and ESD (100%). In conclusion, we affirm that the percentage of positivity to challenge tests rose in parallel to the increasing number of diseased vessels, and that ET and ESD are of reciprocal value and both are fundamental in the evaluation of post-infarction residual ischemia.
我们对35例急性心肌梗死（AMI）患者（4例女性和31例男性）进行了研究，在症状出现后的20天内使用了测力计测试（ET）、多巴酚丁胺负荷超声心动图试验（ESD）和冠状动脉造影。5.7%的患者未显示明显的冠状动脉病变。该组中50%的病例ET呈阳性，31.4%的患者被诊断为单支冠状动脉疾病，该组中33.3%的患者ET和ESD对残余缺血呈阳性。大多数患者（42.8%）患有双支冠状动脉疾病，该组中分别有45.4%和53.8%的患者ET和ESD对残余缺血呈阳性。20%的患者表现为三支冠状动脉疾病，在该组中大多数患者ET（83.8%）和ESD（100%）均呈阳性。总之，我们确认激发试验的阳性率与病变血管数量的增加平行上升，并且ET和ESD具有相互补充的价值，两者在评估梗死后残余缺血方面均至关重要。
