A study just published shows that in people with atrial fibrillation who took warfarin long-term, there was a decreased risk of developing dementia. This was atrial fibrillation, not valves, and the effect was slight. What I think is important though is that it did not show an increased risk of dementia.

The reference is:
Barber M, Tait RC, Scott J, Rumley A, Lowe GD, Stott DJ. Dementia in subjects with atrial fibrillation: hemostatic function and the role of anticoagulation. J Thromb Haemost. 2004 Nov;2(11):1873-8.

There have also been studies that it is mildly protective from developing cancer. Not absolute, of course, but slight.
 
Is that among only people with atrial fib or the population in general? In other words, am I lucky to have atrial fib and be on coumadin vs not having atrial fib at all or does coumadin help me, as an atrial fib patient, to better avoid dementia? OR, do I already have dementia and am not making any sense?

Hip..Hip..Hooray for the coumadin...Maybe the Rat poison is good.. :D After posting .3,285 posts on VR.Com... I can still remember..every member..their surgeries..when they post, ect....No dementia here..for an age 64 year old Lady... :D And..am so thankful..No cancer..either. ;) ..I love my little pink pill. I take every day. ;) ;) Bonnie
 
They were only studying people with atrial fibrillation. The study was not designed to just look at dementia, but a number of things including levels of the remnants of blood clots in their blood etc as well as quality of life.

I don't think that the big thing here is that it it was just done in atrial fibrillation patients. Neither is the big thing that it slightly prevented dementia. I think that the big thing is that it was not causing harm.

When you think about how crude drug development was when warfarin was discovered (invented), I think that it is amazing that it has so toxic effects. People are asked to take this drug for the rest of their lives, so the concern is, "what damage is it likely to cause"? When the answer is. "very little other than bleeding" and it may prevent two dreaded diseases - cancer and dementia - that seems like pretty good news.

This has been born out by people like my Dad who took it for about 25 years (and likely died when some doctor stopped it for some "I'd just like to see how you are doing" test), Joann who has been on it for over 30 years and RCB who now is up to 44 years.
 
A phrase that kept going through my head in the weeks before I had my tricuspid valve replaced:

"That which does not kill you..."


Perhaps some of these drugs that we are on indeffinitely are just that, powerful heart medications that in a "normal, heart-healthy" person would likely kill them or at least do great harm, but for us, maintain life.
Many of these drugs haven't really been around long enough to know long-term implications with any certainty. It's getting better as people get older, but who knows what a life time of diuretic use will do to someone who started diuretic therapy in their late teens and is now 80+ years old? What kind of effect would that have on kidney function, the liver, endrocrine system? We know some drugs like amiodarone are best used for short periods of time, if it all, and only when absolutely neccesary. other drugs don't eem to have immediate consequences like amiodarone, but a life-time of use?

I'm on spironolactone which, among other things, causes breast enlargment in men and skin sensitivities. The breast thing aside, does spironolactone make me more succesptible to skin cancer? I tan MUCH faster now and will easily burn if out in the sun without protection for less than half an hour. My furosemide (lasix) depletes the potassium in my system. I have to compensate for it in part through the spironolactone and by eating foods high in potassium. Those levels fluctuate a lot in my body, what kind of an effect does THAT have long term?


And of course, aside from all of that, no one past the age of about 40 something has the "breed" of transposition of the great vessels that I have. It wasn't fixable before the mid-sixties. I've survived the BIG complication the technique used to "reconfigure" my heart carries, des that mean I'm "home free" now as long as I keep to my meds and take care of myself, or am I headed for more surgery or a heart transplant down the road? No one can say, no one's lived into "old age" with what I have....


From all that I've seen anticoagulation therapy (coumadin) seems fairly safe so long as you "endure" frequent monitoring and keep up with your medications. Going off anticoagulation seems to entail a much greater risk than staying on it and any side-benefit the medication might provide is almost "inccidental" to me at least. Ok, so maybe it will stave off dementia. that's never been a problem in my family, usually such conditions are hereditary.

Oh, and my family has a long list of decendants that have lived well into their 80's and 90's. My mother's parents are still alive and fairing well at 92 and 95.
I'm the only one in the family (within the last 100 years at least) that's had a heart condition like the one I was born with. Congenital heart defects are non-exisitant in my family otherwise. Sometimes such things run through generations, I appear to be an anomaly. :D
 
Happy to hear this. At 78 I'm still working halftime and my associates assure me they see no signs of dementia. Al, how does warfarin effect the risk of hemorrhagic stroke? Have there been any studies?
 
A warfarin complication.

A warfarin complication.

Last Sunday ,six days ago I took a bad tumble going after a ball in a steep bunker. I was able to get up and get home, but later that evening I developed what I thought was a cramp in my left anterior thigh. The leg got very tight and pale. One of my daughters works for an orthopedic group and discussed it with one of the doctors. He said:"This is an emergency, have him get an MRI and then come out here with the films.We must rule out compartment syndrome." The MRI showed extensive diffuse hemorrhage involving the entire quadriceps anterior muscle compartment.. The doc said he did not want to open it because the muscle would pop out of the incision like a blood soaked sponge and the incision could not be closed but would need a skin graft later. He prescribed bed rest( leg at heart level), a walker, Percoset, and call my cardiologist about stopping warfarin.I tested by Coaguchek the day before the accident-INR 3.6. I held three days and today was INR 1.6.The pain( 8 on scale of 10) finally let up a little yesterday, the muscle softer, with purple skin blotches, and I can walk a little ,so accoring to the cardiologist, I can "gingerly" start back on the warfarin. My normal weekly dose is 3mgm/day @ 21mgm /week. I took a 2.5 mgm today and will take daily for a week ,17.5mgm and hope there is no more muscle bleeding and of course no valve clotting.They want me to keep the INR closer to 2.5 from now on. I'll keep you all informed. Al do you agree with this dose?
 
The dose sounds reasonable, Marty. Sorry about the injury, especially on what was supposed to be a day of fun. Glad that you were not hurt any worse than you were - broken bones etc.

I'm don't think anyone has put numbers on the risk of cerebral hemorrhage. I do know that in my clinic that all major bleeding in about one incident per 33 patient years. So, it would be less than that.
