Implication
May indicate continued recovery beyond 5 weeks after anterior MI; supports hibernating myocardium hypothesis but remains hypothesis-generating.

Outcome
Resting regional blood flow distribution (perfusion defect severity) and contraction (extent of abnormal wall motion and left ventricular ejection fraction) assessed at 5 weeks and 7 monthssurrogate
In patients with anterior Q-wave infarction, recovery of perfusion and contractile function may continue to improve significantly between 5 weeks and 7 months, suggesting the presence of hibernating myocardium.
