I have a 45 year old brother who is a brittle diabetic, according to enzymes he had a heart attach last week. 2 catherzations, that found a blockage from a bad stint. He had new stints put in. That was 5 days ago. since then his heart rate has remained around 130 only falling to 104 for an hour or so. His BP is being kept up at 90/60 with meds. It falls to 60/40 without meds. His o2 sat. is good, but he is SOB with labored breathing. they are using a B-PAP and are considering a ventilator. The doctors are stumped. They found nothing remarkable on the 2nd cath. He is extremely fatigued and confused most of the time. We are considering moving him from the hospital he is in to Cleveland Clinic in Cleveland in hopes of finding the underlying cause. He also was septic at admission but that seems to have been resolved with antibiotics. help
