Cardiac exercise stress testing has both diagnostic and prognostic implications. ECG changes, hemodynamic responses, and symptoms during exercise are clues to the functional capacity, severity of coronary artery disease, and probability of future coronary events. The time and workload required for a positive response to exercise and the length of time the ECG changes persist during recovery are indicators of the degree of coronary disease and are useful in predicting future coronary events.
心脏运动负荷试验具有诊断和预后意义。运动期间的心电图变化、血流动力学反应及症状是提示心功能、冠状动脉疾病严重程度和未来发生冠状动脉事件可能性的线索。运动出现阳性反应所需的时间和负荷量以及恢复过程中心电图变化持续的时间是冠状动脉疾病程度的指标，对预测未来冠状动脉事件很有用。
