JACC: 82Rb myocardial flow reserve with MPI stratifies cardiac risk

Myocardial flow reserve quantified using rubidium-82 (82Rb) PET predicts hard cardiac events and major adverse cardiac events independent of the summed stress score and other parameters, according to research published Aug. 9 in the Journal of the American College of Cardiology. Therefore, the researchers recommended that routine assessment of 82Rb PET-quantified myocardial flow reserve could improve risk stratification for patients being investigated for ischemia.
