[|Human|] Hi! My father just got a call from his DR stating his Hemoglobin is at 6.5 and is very low and needs to get the the ER. He is going to the ER tomorrow morning. What can this be? He is 66 yrs old and is on Cumidin for his heart due to a past heart attack. Is he going to be ok?
[|AI|]  Hi, Considering the age, recent heart attack, medication and low hemoglobin, my advice is as follows He is going to be OK. Hemoglobin of 6.5% is very low, especially with a compromised cardiovascular system. It could increase the risk of another myocardial infarction. He might require a packed cell RBC transfusion and the based on lab result specific therapy with vitamin or iron. Also he needs to go on a nutritional diet to avoid similar problems in the future. Any further queries, happy to help again.
