[|Human|] My wife EF was 15 to 20%in Sept 2016. It suddenly dropped to that level. Doctors suspected viral or stress cardiopathy. She also developed hypothyroidism after MVR in Jan 2016 but that time her EF was 55% and was put on amiodrone plus dirutics. Her Thyroid is normal Can her EF improve now..pls also tell how her EF can be improved. I m writting from India. Thnx
[|AI|]  HelloWelcome to Ask a Doctor service. I have reviewed your query and here is my advice. EF 15 to 20 % is indicative of left ventricle failure it is the medical emergency, it can not be due to infection (Viral) unless it is the life-threatening and severe infection condition demands the immediate medical attention, second it has to be correlated with the clinical condition, if patient is doing well then report of echo need to be repeated on another echo machine. Hope I have answered your query, let me know for further assistance,
