They are both: essentially normal. There are many variables including the technicians drawing skill, doctors distraction and quality of images that affect the number. The key is they are both close enough to 50% (Normal) to say they are normal and there is no weakness identified. Take this as a pass/fail rather than an A-B-C-D-F. You pass!

What is a normal EF?: Both methodologies described (cath vs nuclear medicine techniques) are generally reliable but, having said that, nothing beats a properly performed echocardiogram for this evaluation (except for a MUGA scan). Visit with your cardiologist as this EF number always needs to be evaluated in a clinical context-you could have a great systolic function and a poor diastolic one...take care!

Need more informatio: It is important to give us information about your medical history? Why did you have Heart Cath done in the first place? Do you have history of heart disease? Any heart attacks in the past?.Without this history we can not interpret your Ejection fraction(EF). On surface, you have normal EF. There is expected to be some change in % EF, every time it is checked. Value of 50 and over is normal/safe.
