Prognostic value of heart rate response during regadenoson stress myocardial perfusion imaging in patients with end stage renal disease

Background Blunted heart rate response (HRR) to vasodilator stress agents is associated with worse outcomes. There are limited data assessing the effect of impaired HRR to regadenoson among patients with end-stage renal disease (ESRD) undergoing stress myocardial perfusion imaging (MPI).
