前瞻性评价急性心肌梗塞(AMI)早期超声心动图-多巴酚丁胺应激试验(DSE)预测AMI预后的准确性。 方法 214例急性心梗患者,均为男性,年龄(57±13)岁,于入院后2～7天行DSE,其中193例行冠脉造影。所有病例均随访1年以上或至发生严重心脏事件。 DSE:多巴酚丁胺按5、10、20、30、4Qμg/(kg·min)浓度静脉输入,每浓度静滴5分钟,如心率未达预期目的,则以阿托品(每2分钟
Prospective Evaluation of Acute Myocardial Infarction (AMI) Early Echocardiography - Dobutamine Stress Test (DSE) Predict the Accuracy of AMI Prognosis. Methods A total of 214 patients with acute myocardial infarction, both male and 57 ± 13 years old, underwent DSE 2 to 7 days after admission, of whom 193 underwent coronary angiography. All cases were followed up for more than 1 year or until a serious cardiac event occurred. DSE: Dobutamine was intravenously injected at concentrations of 5, 10, 20, 30 and 4 μg / (kg · min) for 5 minutes at each concentration. If the heart rate did not reach the expected goal,
