Abstract

Ischemic ECG changes during dobutamine stress echocardiography (DSE) have been reported to have low sensitivity and specificity for detecting myocardial ischemia in the absence of wall motion abnormalities on echocardiography. We present a case of a renal transplant candidate with severe multivessel disease who had ST depressions without any wall motion abnormalities on DSE. Certain studies have shown the sensitivity of DSE is lower in patients with left ventricular hypertrophy and/or end stage renal disease, but the significance of ischemic ECG changes with no evidence of wall motion abnormalities in these patients has not been well studied.
