[Comparison of the data of the veloergometric test and coronarography in ischemic heart disease].
The results of the bicycle ergometry test were compared with the findings of coronarography in 254 patients with ischemic heart disease or suspicion of it. The high diagnostic significance of the test was demonstrated; stenosis of the heart coronary arteries was found in 73% of patients producing a positive test. The occurrence of an attack of angina pectoris with simultaneous "ischemia" reduction of the ST segment by 1 mm and more is a significant sing of a positive test. The severity of changes in the coronary arteries grows when these signs are combined with poor tolerance of physical load. With the higher degree of stenosis and an increase in the number of involved arteries load tolerance decreases, while the percentage of positive results of the load test increases.
