In 82 CHD male patients aged 35-54 years with well-preserved working capacity (threshold load, 600-750 kgm/min) who had underwent bicycle ergometer test, the time course of changes in the major hemodynamic parameters was found to be significantly similar to that of healthy individuals. The cases who stopped performing bicycle ergometer tests because of anginal attacks, and ST segment depression or either showed a more significant elevation in systolic and diastolic blood pressure at the maximum load rate and lower increase in heart rate than in healthy subjects, which may be regarded as a compensatory mechanism that prevents a further decrease in coronary flow. Diminished increase in stroke index and cardiac index suggests reduced myocardial contractility.
在82名年龄在35 - 54岁、工作能力良好（阈负荷为600 - 750千克米/分钟）且接受过自行车测力计测试的冠心病男性患者中，发现主要血流动力学参数的变化时间过程与健康个体显著相似。因心绞痛发作、ST段压低而停止自行车测力计测试的患者，在最大负荷率时收缩压和舒张压升高更为显著，心率增加低于健康受试者，这可被视为一种防止冠状动脉血流进一步减少的代偿机制。每搏指数和心指数增加减少表明心肌收缩力降低。
