What does an ejection fraction of 91% indicate?
Patient: I just had a stress test and the doctors office said my results were good. I asked for a copy of the report and the report says that my ejection fraction is 91 %. I did some reading and learned the 50 to 70 % is normal. So I guess my 91% IS HIGH. Does that mean that my test results are not good and that I need to see a specialist? Doctor: Hello, Brief Answer: During stress or exercise, your heart ejection fraction increases.Explanation: My opinion is that during vigorous exercise or excessive stress, the heart responds by increasing both heart rate and function. That is meant by ejection fraction. In normal conditions, ejection fraction ranges from 50 to 70 %. Ninety percent ejection fraction may be a little bit overestimated but as long as there’s the test is negative, nothing to worry about. The information provided by you is not sufficient to provide a good opinion. If someone comes to me with this condition I would ask them about hydration status during the stress test.Conclusion: I suggest you check with your physician.Hope I have answered your query. Let me know if I can assist you further.Regards,   Dr. Mahmmad Gamal
