<s>[INST] hi my dad is 67 but had a heart attack 11years ago. He has diabeiteis, high blood pressure and rheumatoid arthritis. He's been retaining water alot more over the last few months and has had several hospital visits to help pass out the extra water that the medication hes taking is not doing fast enough. They say his heart is working at 10% now, he has a difibulator which didnt shock him back in december when he lost consciousness due to a lack of oxygen to the brain. We do believe he is having renal problems as well but the doctors take blood test and say  its fine. Whats the likely hood of life expectancy when his heart is so weak? [/INST] Not long unfortunately..as 10% efficacy is too low for the heart to do his prober work and supply the blood requirements for the whole body...it ranges from few months to a year... </s>
