Warfarin rears its ugly head

I swear I have seen more intracerebral hemorrhages fromCoumadinin the last year than in the any of the literature stating it's incidence. Last night I admitted an elderly gentleman who was in his usual state of health until he slipped on the ice and bumped his head. He then carried about his business for a day and a half. Then as he went to work his secretary noted him acting unusual.

When he showed up in my Emergency department, he had anINRof 9.4

For all of those who don't know what an INR is, 1.0-1.4 is normal. This is abnormal, big time.

He had traditionally been on a very low dose of coumadin (I.E.poor metabolizer) The problem was not that he just had very thin blood, the problem was the huge bleed he had in his brain!
What can we do about this problem? I have mentioned the future of coumadin therapy severaltimes. I was just speaking toDr Isadore Rosenfeldyesterday who pointed out to me that a recentstudyonce again shows how beneficial Warfarin is in preventing strokes caused by a condition known as Atrial Fibrillation. The incidence of Atrial fibrillation increases as the population ages. Therefore, I am certain that we will begin to see more poor metabolizers and even more poor outcomes.
The Sherpa Says: On Coumadin? Mind your INR? Starting Coumadin? Get your metabolizer status checked! If you are in NYC or Greenwich come see us. Thank you to GTO for the early Christmas present....
