[The early bicycle ergometry test in drug-stabilized patients with unstable angina pectoris--the correlation with coronary angiography].

The relation between the results of the early submaximal symptom-limited bicycle ergometry [correction of veloergometric] test and coronary angiography were examined in 127 patients with unstable angina pectoris stabilized by medicaments. In 19 (15.0%) patients the test was negative and in 108 (85%) patients the test was positive (angina pectoris and/or ST depression greater than or equal to 0.1 mV at 80 ms after the point J of the ECG). Between the results of the early bicycle ergometry [correction of veloergometric] test and the coronary angiography, performed soon after the test, there was a close correlation. By using strict criteria or a combination of criteria for assessment of residual ischemia the test can with great accuracy differentiate the patients with multivascular from those with monovascular disease or with healthy coronary vessels.
