Background: Although heart rate response (HRR) to regadenoson stress has been shown to be a strong predictor of outcome, it has not been investigated in a large all-comers cohort. The prognostic utility of systolic blood pressure response (SBPR) has not been investigated in comparison with HRR.
Methods And Results: In a retrospective cohort of 10,227 patients undergoing regadenoson stress single-photon emission computed tomography myocardial perfusion imaging (MPI), HRR, and SBPR were calculated as 100×(peak hyperemia value-baseline value)/baseline value.
