current study aims to evaluate

late evolution (after one year) of patients with discordant MIBI-Tc-99m perfusion SPECT(MIBI) and exercise stress test (EST) results. MIBI was considered positive when a reversible perfusion defect was present in at least one segment; EST was considered positive when ST downslope = > 1mm and/or chest pain was present. One hundred and twenty patients were reviewed. Twenty two had ischemia-negative EST and ischemia-positive MIBI (group I) and 98 had ischemia-positive EST and ischemia -negative MIBI (groupII). In group I 7/22 patients (31,8%) had late cardiovascular events. In group II only 10/98 (10,2%) had those events.

results confirm that in cases where EST and MIBI are discordant, MIBI shows

best correlation with coronary events in

late follow up
