据英国《The Lancet》1993年342卷第8879期报道 Myers等人对急性心肌梗塞病人进行各种试验以检测是否缺血、左心室功能减退和心律失常,并与心脏病专家预测病人心梗后一年的结果进行比较,本研究对象限于65岁以上、心血管疾病预后危险度较大而又较少进行介入性手术的病人。 对病人的心脏病医生依据标准额定尺度,临床所见以及常规医院检查来预测后果。在见到无损伤性检查结果之后作出第二次预测。在操作特性曲线区域内,将测得的结果进行评估,比较第一、二次预测的差异。在一年的随访期间,147例病人中有24例
According to the British “The Lancet” 1993 Volume 342, Volume 8879 reported Myers et al. Acute myocardial infarction patients were tested in various tests to detect ischemia, left ventricular dysfunction and arrhythmia, and cardiologists predict the patient after myocardial infarction The results of one year were compared. The study was limited to patients over 65 years of age who had a greater risk of cardiovascular disease and fewer interventional procedures. The patient’s cardiologist predicts the consequences based on the standard ratings, clinical findings, and routine hospital tests. Make a second prediction after seeing the non-invasive test results. In the area of the operating characteristic curve, the measured results are evaluated to compare the differences between the first and the second prediction. During the one-year follow-up, 24 of 147 patients were followed
