The remote results of aorticocoronary shunting were studied in 105 patients (follow-up periods of 1 to 5 years and more). The values of bicycle ergometry and spiroergometry (rehabilitation coefficient, oxygen expenditure per 1 kgm of work, maximum oxygen consumption per 1 kg body mass during muscular exertion, effectiveness of work) were studied before and after operation. The data obtained were compared with the results of spiroergometry in 175 patients with various lesions of the coronary arteries identified by coronarography and in 50 healthy individuals. Spiroergometry is an effective method for diagnosing coronary atherosclerosis before performing coronarography. Patients with good postoperative results showed values which were close to normal; in poor results of surgery and in thrombosis of the coronary shunts initial values characteristic of atherosclertoic involvement of the coronary arteries are encountered. Increase of the effectiveness of work to normal, decrease in oxygen expediture per 1 kgm of work, diminution of maximum oxygen consumption per 1 kg body mass during muscular exertion in the remote postoperative period make it possible to presume, before performing coronarography, that the shunts are functioning. The study conducted allow bicycle ergometry and spiroergometry to be considered demonstrative functional methods for appraising the remote results of operation.
对105例患者（随访期1至5年及更长时间）的主动脉冠状动脉分流术远期结果进行了研究。在手术前后对患者进行了自行车测力计和肺功能测力计测试（康复系数、每千克工作量的耗氧量、肌肉运动时每千克体重的最大耗氧量、工作效率）。将获得的数据与175例经冠状动脉造影确诊为各种冠状动脉病变的患者以及50例健康个体的肺功能测力计测试结果进行了比较。肺功能测力计测试是在进行冠状动脉造影之前诊断冠状动脉粥样硬化的有效方法。术后效果良好的患者其各项数值接近正常；手术效果不佳以及冠状动脉分流处出现血栓形成的患者，会出现冠状动脉粥样硬化累及的初始特征性数值。在术后远期，工作效率提高至正常水平、每千克工作量的耗氧量降低、肌肉运动时每千克体重的最大耗氧量减少，这些情况使得在进行冠状动脉造影之前可以推测分流术正在发挥作用。所进行的研究使得自行车测力计和肺功能测力计测试可被视为评估手术远期结果的具有指示性的功能方法。
