OBJECTIVES We hypothesized that fractional flow reserve (FFR) of an infarct-related artery (IRA) early after myocardial infarction (MI) identifies inducible ischemia on noninvasive imaging. BACKGROUND Early after MI, IRAs frequently have angiographically indeterminant lesions. Whether FFR can detect reversible perfusion defects early after MI when dynamic microvascular abnormalities are present is not known. METHODS Rest and dipyridamole (DP)-stress 99mTc sestamibi single-photon emission… CONTINUE READING
