准确的预后信息是重要的，在确定最佳的管理病人提出的胸痛评估。在139名连续的、非手术治疗的患者中，运动Tl-201心肌成像预测未来心脏事件（心血管死亡或非致命性心肌梗死）的能力与临床、冠状动脉和左心室血管造影以及运动ECG数据相关，这些患者随访3-5年（平均随访，3.7 ± 1.5年）。0.9），使用逻辑回归分析。在既往无心肌梗死的患者中（139例中的100例），当评估所有患者变量时，具有短暂Tl-201缺陷的心肌节段数量是未来心脏事件的唯一统计学显著预测因素。在评估前的心肌梗死患者中（139例中的39例），当考虑所有变量时，血管造影射血分数是未来心脏事件的唯一重要预测因素。这项研究提出了一种评估可能患有缺血性心脏病的患者未来心脏事件风险的方法。
Accurate prognostic information is important in determining optimal management of patients presenting for evaluation of chest pain. The ability of exercise Tl-201 myocardial imaging to predict future cardiac events (cardiovascular death or nonfatal myocardial infarction) was correlated with clinical, coronary and left ventricular angiographic as well as exercise ECG data in 139 consecutive, nonsurgically managed patients followed up over a 3-5 yr period (mean follow-up, 3.7 .+-. 0.9), using a logistic regression analysis. Among patients without prior myocardial infarction (100 of 139), the number of myocardial segments with transient Tl-201 defects was the only statistically significant predictor of future cardiac events when all patient variables were evaluated. Among patients with myocardial infarction before evaluation (39 of 139), angiographic ejection fraction was the only significant predictor of future cardiac events when all variables were considered. This study suggests an approach to evaluate the risk of future cardiac events in patients with possible ischemic heart disease.
