This is a very good question. I can understand that you might be concerned about getting a different ejection fraction value from each test.
Ejection fraction is a test that determines how well your heart pumps with each beat. In most cases, the term "ejection fraction" refers to left ventricular ejection fraction. This is the measurement of how much blood is being pumped out of the left ventricle of the heart with each contraction. The left ventricle is the main pumping chamber of the heart.
Ejection fracture can be measured by a stress test, nuclear stress test, coronary catheterization, MRI scan of the heart, echocardiograhy, and a CT scan of the heart.
These diagnostic tests vary in degrees of what information they provide. A stress test measures how your heart and blood vessels respond to exertion. During a coronary catheterization or angiogram, your cardiologist may have done a ventriculogram, which is a procedure to determine the strength of your left ventricle.
The results of the coronary catheterization are more accurate because your cardiologist received more information and was able to make a diagnosis of non ischemic cardiomyopathy.
This probably explains the difference in the two test results. Always consult your cardiologist to be absolutely certain of this.
