Key result
The presence of ischemia by myocardial perfusion imaging after PCI independently predicted major adverse cardiovascular events at 1 year (OR 5.09; 95% CI 2.15-12.05; p < 0.001).
Why the study?
Does the presence of ischemia on myocardial perfusion imaging predict major adverse cardiovascular events in patients after percutaneous coronary intervention?

Does the presence of ischemia on myocardial perfusion imaging predict major adverse cardiovascular events in patients after percutaneous coronary intervention?
Myocardial ischemia detected by MPI, rather than symptom status, is a strong independent predictor of MACE at 1 year following PCI.
The aim of this study was to evaluate the value of myocardial perfusion imaging (MPI) in predicting major adverse cardiovascular events (MACE) in symptomatic and asymptomatic patients after percutaneous coronary intervention (PCI). We revised retrospectively patients after PCI that underwent MPI and were followed for a year for the presence of MACE. We found no differences in the incidence of MACE between symptomatic and asymptomatic patients. On multivariate analysis, the presence of ischemia by MPI was the most important independent predictor of MACE (OR 5.09, CI 95% 2.15-12.05, p < 0.001). The presence of myocardial ischemia by MPI performed after PCI, and no symptom status, predicts a worse outcome during 1 year of follow-up.

Solodky et al. (2006) conducted a cohort in Patients after percutaneous coronary intervention (PCI). Presence of ischemia by myocardial perfusion imaging (MPI) vs. Absence of ischemia by MPI was evaluated on Major adverse cardiovascular events (MACE) (OR 5.09, 95% CI 2.15-12.05, p=< 0.001). The presence of ischemia by myocardial perfusion imaging after PCI independently predicted major adverse cardiovascular events at 1 year (OR 5.09; 95% CI 2.15-12.05; p < 0.001).
