Key result
The presence of redistribution (ischemia) on rest thallium imaging was an independent predictor of death compared to no ischemia (58% vs 26%; p=0.03).

Does the presence of redistribution on rest thallium imaging predict mortality in medically treated patients with coronary artery disease and left ventricular dysfunction?
Absolute Event Rate: 58% vs 26%
p-value: p=0.03
In medically treated patients with coronary artery disease and left ventricular dysfunction, the presence of redistribution (hibernating myocardium) on rest thallium imaging is an independent predictor of higher mortality.
Gioia et al. (1996) conducted a cohort in Coronary artery disease and left ventricular dysfunction (n=81). Redistribution (ischemia) on rest-redistribution thallium 201 imaging vs. No redistribution (no ischemia) was evaluated on Cardiac death (p=0.03). The presence of redistribution (ischemia) on rest thallium imaging was an independent predictor of death compared to no ischemia (58% vs 26%; p=0.03).
