Summary

This study tested whether a special heart scan (SPECT) can predict how well patients with ischemic cardiomyopathy will recover after heart surgery. 120 patients underwent imaging at rest and during stress to measure heart function and blood flow. The goal was to find patterns that indicate which patients are likely to see improvement.
