Ejection fraction on Echocardiogram 45-50% but onnk CMRI 67%. Which is most accurate? Why discrepancy?

Accuracy dependent. The acuracy of an echo dependent on operator & time alloted&the equip. Having said that, NL EF of echo is >55%. So if looks NL, will be called 55%. Thus, # not written in stone, consensus opinion. No Measurement is perfect because of technical reasons. Best measure `considered' Nuclear. Does require radioactive nuclide injected, NL if EF >50%. Not perfect measure either. Experienced reader helpful. Read more...

During routine echocardiogram, is the ejection fraction usually calculated using the m-mode estimate, or the 2d volume (tracing the lv) measurement?

Either. Both methods are used. However, it is generally accepted that tracing the endocardial borders of the left ventricle at end systole and end diastole in two separate planes gives the best estimate of ejection fraction. When using only the m-mode tracing, there are many assumptions built into the estimate of ejection fraction that can challenge accuracy. Read more...

Echocardiogram 2.5 years ago normal ejection fraction 60-65%. Now normal but ejection fraction 55% is this a bad sign or just variable? Just ectopics

"Normal" hard to jud. Basis for designating an ejection frac (EF) as "normal" isn't just the pictures that are seen, but also knowledge of your medical condition- symptoms & signs. Any echocardiogram has variability - a calculated EF of 55% means the EF can range from 50%-60% (+/-5%). Similarly, 2.5 yrs ago, EF was probably in the range of 57%-67%. There's considerable overlap, so it's hard to say if anything changed. Read more...

Echocardiogram: How can I have a 55-60% ejection fraction with a 37 mL stroke volume?

Diastolic heart fail. In constrictive heart diseases (like constrictive cardiomyopathy, pericarditis, diastolic dysfunction, & hypertensive heart diseases), the heart fails to relax in diastole to bring enough blood to the left ventricle. In that situation, you may be only getting about 70 mL in the LV, so an ejection fraction of 55-60% (which is "normal") only puts out about 37 mL (as opposed to 140 mL in, 70 mL out). Read more...
