I have an AO claim for IHD with an EF of 17% and a METS of 1-3. I also have Type II Diabetes (on insulin 4 times/daily), ED, being treated for anxiety and recovering from a quadruple by-pass (CABG). I'm 62 and running short on time. Any idea how to calculate survivor benefits? I have a wife 49, a 12 year old daughter and an 82 year old mother all living with me. My claim is from 2010 and is making headway. I just met with a VA Dr. to verify my 20 year/450 page documents. Any suggestions to maximize survivor benefits. Thanks, Sgt D.
