Based on 7 previously published original papers the present review evaluates the response to an exercise test during early recovery from acute myocardial infarction. Selected exercise variables are related to the long-term survival of the patients. The conclusions can be summarized as the following: The exercise test can be carried out with sufficient safety. The exercise physiological response of the patients is dependent on their age, sex and reason to discontinue exercise. ST-segment depression is not significantly predictive of subsequent mortality. Other categories of the ST-segment response are of limited value as prognostic predictors. An exercise index of left ventricular function and exercise associated ventricular arrhythmias are independent, significant predictors of the long-term survival of the patients, regardless their age. These variables can identify a substantial number of patients with a very low subsequent death rate, irrespective of a clinical risk stratification. Different degrees of increased risk of dying can be determined by combining exercise and clinical variables. The prognostic significance of exercise induced ventricular arrhythmias is related to their frequency and the occurrence of repetitive ventricular premature beats.
基于7篇先前发表的原创论文，本综述评估了急性心肌梗死后早期恢复期间对运动试验的反应。选定的运动变量与患者的长期生存相关。结论可总结如下：运动试验可以安全地进行。患者的运动生理反应取决于他们的年龄、性别和停止运动的原因。ST段压低对后续死亡率没有显著预测作用。ST段反应的其他类别作为预后预测指标的价值有限。左心室功能运动指数和运动相关室性心律失常是患者长期生存的独立、重要预测指标，与年龄无关。这些变量可以识别出大量后续死亡率极低的患者，而不考虑临床风险分层。通过结合运动和临床变量可以确定不同程度的死亡风险增加。运动诱发室性心律失常的预后意义与其频率和重复性室性早搏的发生有关。
