Had a muga scan of the heart-- first time it was 59 percent second time 51 percent just had another one and it was 70 percent --what does that mean?

A MUGA scan measures the heart's ejection fraction, which indicates how well the heart is pumping blood. Your results show fluctuations in ejection fraction: 59% is within the normal range, 51% is borderline low, and 70% is considered good. These changes could be due to various factors, including improvements in heart function, changes in medication, or variations in test conditions. It's essential to discuss these results with your healthcare provider for a comprehensive assessment and appropriate recommendations.
