Role of Myocardial Perfusion Imaging in Patients With End-Stage Renal Disease Undergoing Coronary Angiography

Patients with end-stage renal disease (ESRD) are at high risk of cardiovascular events. This study examined the prognostic power of stress myocardial perfusion imaging (MPI) in 150 patients with ESRD (mean age 53 ± 9 years; 30% women; 66% with diabetes mellitus) being evaluated for renal transplantation with known coronary anatomy using angiography. Baseline data in addition to perfusion and angiographic parameters were compared between survivors and nonsurvivors. All-cause mortality was defined as the outcome measure. An abnormal MPI result was present in 85% of patients, 30% had left ventricular (LV) ejection fraction (EF) ≤40%, and 40% had multivessel coronary artery disease using angiography. At a mean follow-up of 3.4 ± 1.5 years, 53 patients died (35%). LVEF ≤40%, LV dilatation (LV end-diastolic volume >90 ml), and diabetes mellitus were associated with higher mortality (all p
