Usefulness of tachycardic-stress perfusion imaging to predict coronary artery disease in high-risk patients with chronic renal failure.
Uncertainty remains as to the most appropriate preoperative screening investigation to evaluate patient cardiac risk in prospective renal transplant recipients. We prospectively compared tachycardic-stress (exercise/pacing) scintigraphy with coronary angiography for the detection of significant coronary artery disease in this group. With a negative predictive value of 92%, tachycardic-stress scintigraphy may reduce the need for unnecessary coronary angiography in these patients.
