my dad 56 years old had a heart attack this past june followed shorty by kidney failure. He was mis diagnosed with pnemonia and one thing led to another. Without getting into all that, it was a long summer. He had the cath surgery only to find he didn't need it (saying he didn't have a heart attack) followed by a blood clot that sent him straight back to the or, this time he returned to us on a vent because he was having seizure type symptoms and blood pressure that shot way up to way low. (can't quite remember the numbers but it was bad.) he was in icu for a few days this way, and a few more for monitoring. Spent a couple days on the regular floor and sent home. He then had a problem with the surgery from the blood clot (home nurse sent him back to er) because they didn;t change his bandages and it turned green blah blah blah. He continued getting sick again which led us to transfer him before they killed him.(act of congress when someone is a vetern or so we were told) He ended up in another hospital with kidney failure to find he had been given too much of a drug he wasnt suppose to have until some levels were checked. Its been about two months now since he has been home(he had dialysis) and he is now in bed throwing up and complaining that his left arm is hurting. He is under blankets cold but is very sweaty, we can't get him to go to doctor. Should we be alarmed about a heart attack? He is a smoker and they told us if he didn't quit he would end up where we started. He quit for weeks(mostly the ones he was in hospital for.)
