Working capacity of 87 coronary patients with stable angina was assessed on the basis of a functional classification of the results of non-invasive investigations (resting ECG, bicycle ergometry, echocardiography). Bicycle ergometry proved to be the most informative method providing indirect evidence of coronary reserve. An objective assessment of the condition of coronary patients can be made using values of exercise tolerance (threshold capacity and volume of work), heart rate and double product at the peak of exercise. A close correlation exists between the severity of atherosclerotic affection of coronary arteries and individual exercise tolerance, which can be used in the medical evaluation of the working capacity of coronary patients with stable angina pectoris.
基于非侵入性检查结果（静息心电图、自行车运动试验、超声心动图）的功能分类，对87例稳定型心绞痛冠心病患者的工作能力进行了评估。自行车运动试验被证明是最具信息量的方法，可提供冠状动脉储备的间接证据。使用运动耐量值（阈值能力和工作量）、心率和运动峰值时的双乘积，可以对冠心病患者的病情进行客观评估。冠状动脉粥样硬化病变的严重程度与个体运动耐量之间存在密切相关性，这可用于对稳定型心绞痛冠心病患者的工作能力进行医学评估。
