    Abstract:
    41 patients with inferior myocardial infarction underwent both exercise stress testing and coronary arteriography. Coronary arteriography of 15 patients showed high-degree stenosis as well as occlusions of the right coronary artery and/or of the R. circumflexus of the left coronary artery alone. In 14 of these 15 cases exercise stress testing showed a normal result, in one case results were abnormal. However, we detected additional high-degree stenosis of R. interventricularis anterior and/or of R. diagonalis and/or of R. marginalis in the other 26 patients. In 22 of these 26 cases exercise stress testing showed an abnormal result, in 4 cases it was normal. Because of a sensitivy of 84,6% and a specificity of 93,3% we can assume, that abnormal results of exercise stress testing suggest additional high-degree stenosis of the RIVA-vessel system in patient after inferior myocardial infarction. Considering an eventual bypass operation it is possible to narrow the indication for coronary arteriography.
