The indices of pulmonary ventilation and gas exchange, oxygen consumption per 1 kgm of work, the restoration coefficient, the effectiveness of work, etc. were studied at rest, during dosaged physical exertion on a bicycle ergoraph, and in the restoration period in 50 healthy individuals and in 175 patients with ischemic heart disease. Selective coronary angiography was conducted in all of the patients. Spiro-bicycle-ergometry is an informative method in the diagnosis of ischemic heart disease, enabling the physician to presume the presence of coronary sclerosis and judge the degree and extent of involvement of the coronary arteries before performing coronarography. With the gradual increase in the number of involved arteries, there were noted a gradual decrease of the restoration coefficient, diminution of the effectiveness of work, and an increase in oxygen consumption per 1 kgm of load. Changes in spiro-bicycle-ergometric indices in patients with ischemic heart disease and normal coronary arteries had the same trend as those in patients with coronary atherosclerosis.
对50名健康个体和175名缺血性心脏病患者在静息状态、在自行车测力计上进行定量体力运动期间以及恢复期间的肺通气和气体交换指标、每1千克米工作量的耗氧量、恢复系数、工作效率等进行了研究。所有患者均进行了选择性冠状动脉造影。踏车运动肺功能测定是诊断缺血性心脏病的一种信息丰富的方法，使医生能够在进行冠状动脉造影之前推测冠状动脉硬化的存在，并判断冠状动脉受累的程度和范围。随着受累动脉数量的逐渐增加，恢复系数逐渐降低，工作效率降低，每1千克负荷的耗氧量增加。缺血性心脏病且冠状动脉正常的患者的踏车运动肺功能测定指标变化与冠状动脉粥样硬化患者的变化趋势相同。
