[|Human|] My sister in law recently suffered a heart attack.  Her heart is reportedly functioning at 25% according to her doctor.  what does a healthy heart usually function at?  she is also having a lot of fluid buildup.  Does this indicate anything in relation to her heart?
[|AI|]  Hello, What you have mentioned is called ejection fraction. Anything above 55 % is called normal. So for your sister the heart is working at nearly half normal. There is a fluid build up and in all probability it is because of a weak heart. When the function of heart is low, less blood is supplied to the kidneys which in turn MIS quotes it as lack of enough blood in the circulation and over the period of time accumulates fluid to increase the quantity of circulation.  Optimization of medication and treatment to strengthen the heart according to the cause would help her. Regards Chat Doctor.
