In 168 patients with ischaemic heart disease an ergometric loading test on a bicycle ergometer was made before coronarography. A total of 19 patients had on coronarography a finding of significant stenosis of the lumen of the trunk of the left coronary artery--group A. These patients were compared with a control group of 20 patients with confirmed coronary heart disease (narrowing of the diameter of the lumen by 50 or more percent) without affection of the trunk of the left coronary artery-group B. As to the investigated parameters of the ergometric test the two groups differed significantly in the total time of the load (group A: 6.21 minutes, group B: 7.94 minutes, p < 0.05), while in all other parameters--total amount of performed work, sum of depressions of the ST segments during a maximum load, time of onset of stenocardias, time since development of 1 mm depressions of the ST segment, maximal depression of the ST segment in lead V5 and number of leads with ST depressions above 1 mm--no significant difference was found. From the work ensues that from the ergometric loading test the finding of stenosis of the left coronary artery on coronarography cannot be predicted.
对168例缺血性心脏病患者在冠状动脉造影检查前进行了自行车测力计运动负荷试验。共有19例患者在冠状动脉造影检查中发现左冠状动脉主干管腔存在明显狭窄——A组。将这些患者与20例确诊为冠心病（管腔直径狭窄50%或以上）但未累及左冠状动脉主干的患者组成的对照组——B组进行比较。就运动负荷试验的研究参数而言，两组在负荷总时间上有显著差异（A组：6.21分钟，B组：7.94分钟，p<0.05），而在所有其他参数上——所做的总功、最大负荷时ST段压低总和、心绞痛发作时间、ST段压低1mm后的时间、V5导联ST段最大压低以及ST段压低超过1mm的导联数——未发现显著差异。由此得出，从运动负荷试验无法预测冠状动脉造影检查中左冠状动脉狭窄的情况。
