help! husband in end stage heart failure

  my husband is in end stage heart failure,i think. his heart was damaged by heart attack,and then he was diagnosed with cardiomypathy.,it runs in family. he has a defibrillator. for about 2 months now,his ankles and legs have been swollen to the point he cannot walk well.,they hurt him,and lasix 3 times a day doesn't help. he has black out spells and his defibrillator goes off around 2 or 3 times daily too. his skin is very pasty white with yellow tinge to it. he is not sleeping,though he is on sleeping pills prescribed by doctor as well as o2 for night. he also has copd(bronchitis) everything he eats he throws up,he cant tolerate anything hardly now.,he also has sleep apnea. this is very sad since he is only 44.

  any thoughts? we are going to family doctor tomorrow to get pain pills.,for he is in pain and he tries so hard to be brave. we are christians he is an evangelist,so that helps,but this is not easy to cope with as his wife,either.
