Abstract
Because coronary artery disease is the leading cause of death in patients with end‐stage renal disease, we prospectively studied the prognostic value of dobutamine stress echocardiography (DSE) compared to coronary angiography (CA) as an evaluative tool. Thirty‐three patients at high risk for coronary artery disease were selected from a cohort of 133 renal transplant candidates and underwent both DSE and CA. In this study, the value of DSE was found to exist in its strong negative predictive value (92%). A negative DSE coupled with a negative clinical cardiac evaluation was found to practicably exclude the necessity for CA. DSE can thus serve as a non‐invasive, low cost screening test.
