Abstract

Regional myocardial flow and flow reserve (MFR) were assessed by compartmental analysis of Gd-enhanced MRI first-pass data in 7 patients with atypical chest pain, and In 15 patients with previous transmural myocardial infarction. The FE product (Flow X Extraction coefficient), derived from the modified Kety equation, was measured in regions corresponding to the Tetrofosmine-SPECT fixed defect and In remote normal regions. The FE product at rest and hyperemic FE product were similar in healed revascularized tissues (70.5 +/- 15.6 and 112.5 +/- 19.5ml/mn/100g, respectively) and in normal myocardium. (76.2 +/- 18.3 and 142.2 +/- 33.0, respectively). In contrast, the FEindex (48.8 +/- 15.2 and 60.7 +/- 18.0, respectively, P < 0.01 versus the two previous groups) and the MFR (1.27 +/- 0.20 vs. 1.91 +/- 0.29 in normalregions) were reduced in healed fibrotic tissues when the Infarct-related artery remained occluded. Myocardial flow reserve maps allowed correct Identification of regions corresponding to an occluded infarct-related artery. (C) 2001 Wiley-Liss, Inc.
