My father is 80 years old. He just suffered from a Widow Maker heart attack on Jan 12. He had a heart cath and they put in a stint and 2 balloons. We had been home approx. 1 week and we went back in Tues (24th) with low sodium (121). Saturday (28th), his sodium dropped back to 121. On Sunday (29th), his hemoglobin was 8 and they gave him blood and got him up to 10. Monday they did an upper GI and found nothing as well as stool samples and found nothing. (He had a colonoscopy 6 mos.ago and found nothing) Today, (31st) his hemoglobin is 9.1 and his sodium is 125. He is diabetic but his blood tests average around 114. He has been very healthy prior to the heart attack. In fact, his heart pictures from the cath show a pretty good looking heart, not one like a diabetic. I am fearful they are gonna chalk this up to "old age and this is what happens to old people" - because that is the information I keep hearing. I think there is more going on... Is it possible something happened from the cath, like an aneurism? I am not satisfied with what they are finding. Oh, they say he is producing too much vassopression, and there is not a blocker - so they have been going back and forth with fluid restrictions and then saline all week. I am feeling hopeless and want to kidnap him from the hospital and get him to cleveland clinic for a second opinion. Thoughts?
