99mTc- MIBI gated SPECT imaging is a powerful tool for predictionof future cardiac events. Fixed perfusion defect, diabetes mellitus (DM)and ejection fraction (EF) were independent predictors of cardiacevents. EF is the most powerful factor as an independent predictor ofcardiac events over perfusion parameters. Higher event rate occur morewith patients who had history of DM with fixed perfusion defects andEF less than 50%. Patients with normal perfusion have an excellentevent-free survival rate during follow-up. The results of our study couldbe used to guide the decision process after nuclear testing either byreferring to intervention or conservative management.
