[|Human|] I am 59 and was hospitalized for Congestive Heart Failure.  After several tests were completed, I was told that I needed a new heart.  My heart refraction was 16%.  With the medications that I am taking, my heart refraction is between 50 and 55%.  Is this good and what is the average heart valve refraction percentage?
[|AI|]  Hi Headfirst of all I want to congratulate you for such a wonderful recovery. From the advice of needing a new heart and an Ejection fraction of 16% coming back to an ejection fraction of 50-55% which is near normal range is just wonderful. Yes is very good and normal range of EF varies between 55 to 80%. You just need to follow all the medical advice strictly as these type of recoveries are very rare. Good Luck
