Emergency Pack for Trail Running or Mountain Biking While on Anticoagulants (Coumadin, Xarelto, Pradaxa, Plavix)

This article is a work in progress and is only a description of my strategy for the time being. I hope to learn from readers of this blog about how to better plan for a trail debacle.

Heading out for a trail run on the Pacific Crest Trail

What kinds of things should a person like me, who is dealing with atrial fibrillation and is taking an anticoagulant (I take Pradaxa), carry on a long run in the wilderness? Or during a long mountain bike ride in remote areas?

When the high country in our local wildernesses is not covered with snow, I will generally do runs, nearly every weekend, of anywhere between six to twenty miles. I almost always run alone (except for my trail buddy – Ringo).

Dangerous and a bad idea? Possibly. But this is what I enjoy in life so I don’t plan on stopping any time soon.

The most important piece of equipment is a phone. People complain that everybody is always on their smartphone, and they should NOT be talking on their phones on mountain summits when everybody else is trying to get all Zen-like and self-actualized, and whatever – that’s a different discussion. You certainly don’t even need to have your phone on; but you absolutely should take it with you, and it should be fully charged. The days of getting hopelessly lost and spelling out SOS with rocks hoping a search plane will find you are fading into the past. A smartphone is a GPS and a direct link to help.

I always carry my iPhone in a baggie with my ID and a sheet of paper towel (which I use for unrelated toilet purposes).

Even if there is poor cell phone coverage in your local high mountain or deep canyon wilderness, and a phone call isn’t always possible, I find that a text message can often still be sent. It might take a while but it eventually will be sent, especially if I am moving along a trail.

There is the standard emergency gear that most people take, often called the “ten essentials” which most people carry while in the wilderness. Of course there is truly no such thing as a standard ten essentials and the list of things you carry will vary depending on the season, your skill set, your location, and your past experience.

My generic survival gear

I got out my little survival kit that I typically carry in the wilderness, and of course not everything is pictured here, and I might not even have all of this stuff with me on any given trip. Naturally I will also have other things like food, gels, electrolytes, a jacket, and plenty of water.

What I found in my default wilderness pack is:

Two knives – a mini-leatherman tool and a standard knife. I will only actually carry one of these.

Two lights – a headlamp and a tiny LED flashlight (one is plenty).

Fire starter – a cigarette lighter, birthday candles, a tampon, and hand sanitizer (which I discovered has completely evaporated).

A space blanket, a compass.

Repair gear (Shoe laces, tenacious tape, dental floss)

Pain pills: Vicoprofen samples – okay they expired in 2000 but I’m guessing they are still good (at least for a placebo effect). Missing: Benadryl for allergies or yellow jacket stings, and I probably should have some of my Pradaxa in case I end up unexpectedly staying out overnight. Also missing: small roll of duct tape, safety pins, and my whistle!

Saint Christopher Medal

Oh, and there is a Saint Christopher medal. This one belonged to my grandfather. Well it probably won’t change anything, but it certainly couldn’t hurt. Feel free to substitute your own personal good luck charm.

But what about specific items for the runner on an anticoagulant? Is there anything else beyond the “ten essentials”?

Other stuff: Map with reading glasses (if needed) and some rope

Obviously having a major bleed while running alone in the wilderness would be a disaster. Death is certainly a possibility. How can a trail runner prepare to increase the odds of a good outcome?

I always make sure to let somebody know (usually my wife) where I’m going and I also send her a text (I text “OOTW” short for “out of the woods”) when I get back to my vehicle.

I also wear a Road ID. This way if somebody finds me they will know I am on an anticoagulant. Maybe this won’t help, but it certainly is worth wearing. At least they will be able to figure out why I bled out so quickly (I know – not funny).

Another item I always carry is a bandanna. This can be used for a number of purposes, such as making a field dressing; but I want to have it in case I need a tourniquet. Plus – I have an extra one because my trail dog always has one draped around his neck.

Bandanna

My bandanna came in handy a week ago when my wife Margo (not on an anticoagulant) crashed her mountain bike and punctured her left thigh with her brake lever. I used it to make a compressive dressing before we road our bikes back to where we could get a ride to the hospital.

One item I do not currently have but definitely need to obtain is a Quickclot field dressing. Evidently these things really work and are routinely used in combat situations. It is a topical coagulant (an anti-anti-coagulant?) which helps clot blood and also serves as a physical barrier to bleeding. I’ve been meaning to obtain one of these for a long time. They are available online via amazon.com, and I just ordered one.

quickclot
Quickclot

Question: Will the Quickclot sponge even work on bleeding in an individual who is on a direct thrombin inhibitor like Pradaxa? Answer: I have no idea. I’ll let you know if I ever get a chance to find out.

In case of bleeding the most important first step is to apply direct pressure. As a surgeon I have a lot of experience with this. Usually sixty seconds of direct thumb pressure will stop or slow most bleeding, but of course if you take an anticoagulant it will take longer. Apply direct pressure as long as necessary. Elevate the wound if possible. Don’t try to clean out major wounds as this will restart bleeding – that can be done later at the hospital.

A tourniquet is a last resort, but the bandanna can be used as a compressive dressing if needed.

Please understand that an anticoagulant doesn’t completely stop clotting of blood, it just makes it take longer. Eventually bleeding will stop. Hopefully before all the blood leaves your body!

Bonus – How to stop a nosebleed:

I have been plagued by frequent nosebleeds since I was a child but, oddly enough, I haven’t had a single nosebleed since I started Pradaxa a couple of years ago. The best method I have found is to pinch the nose, fairly tightly, just above the nostrils, and lean forward. Don’t lie with your head back – that doesn’t work. Hold for a full sixty seconds. Repeat as necessary.

If you are, like me, a trail runner or mountain biker on an anticoagulant, I would love to hear from you. Please leave comments and suggestions in the comments area below.

Thanks.

Atrial Fibrillation News Update

Here are a few internet news stories related to atrial fibrillation. In the future I’ll try to update more frequently so I don’t end up with four topics in one blog entry.

OLYMPUS DIGITAL CAMERA

Overall, the increase in risk of heart attack was about 70% in AF patients, even after accounting for other cardiovascular disease risk factors, such as hypertension, high cholesterol, body mass index, and history of stroke and vascular disease. However, when the researchers looked at subgroups, they found that increased risk of heart attack was more than doubled in women and African Americans with AF—but less than 50% for men and whites with AF.

I’m not sure what to say about this – hopefully runners with atrial fibrillation (who hopefully also have other heart healthy lifestyle choices – like a healthy diet, not smoking, reasonable body weight) will do better than the general population. One bit of good news – the blood thinners a fib patients take to prevent stroke also seem to help prevent heart attacks.

pradaxasmall

“Novel” anticoagulants refers to the newer prescription anticoagulants that are used as an alternative to Coumadin (warfarin). Specifically: Pradaxa (which is the one I currently take), Xarelto, and Eliquis.

I can tell you that as a clinician there are not many things more frustrating than prescribing medications for people who are on Coumadin – it seems like it interacts with everything! One of the great things about the newer anticoagulants is that they have less drug interactions – but they still do have potential drug interactions.

Please click on the link to see tables for drug interactions involving Pradaxa (Dabigatran), Xarelto (Rivaroxaban), and Eliquis (Apixaban).

Obviously all of the novel anticoagulants can interact with any other drug that is *ALSO* an anticoagulant – like Plavix or aspirin. Keep in mind that this includes NSAIDs like Alleve (naproxen), Motrin (ibuprofen), etc.

Personally, I completely avoid taking ibuprofen and naproxen – but every once in a while (like after a brutal long run) I will take a Celebrex. Tylenol (Acetaminophen) is fine – no interactions with the anticoagulants (although it has its own issues).

By the way – if you read the article and see a possible drug interaction please don’t stop taking any of your meds – but contact your own doctor immediately for advice.

neautral milk

A recent study has shown that Coumadin (warfarin) actually increases the risk of stroke for people in atrial fibrillation during the FIRST THIRTY DAYS of warfarin therapy. That’s just the first thirty days – the idea is to prevent having a stroke, and that’s what taking Coumadin does.

This finding does not suggest that anything will change – doctors are still going to put people on warfarin to prevent stroke. They just have to get through the first thirty days!

If you are on warfarin and you read this article – please do not stop taking your medication.

Watchman_2

Finally – the FDA has not yet approved the Watchman left atrial appendage closure device by Boston Scientific – but it has given a “vote of confidence.” It appears that this gadget, which is implanted in the left atrium to prevent the formation of the clots that cause strokes, may be approved by the FDA for the US market late this year. The majority of the panel agreed that the Watchman was equivalent to standard treatment with warfarin, but it hasn’t been compared to the new novel anticoagulants (see above).

Atrial Fibrillation Stroke Calculator

OLYMPUS DIGITAL CAMERA

Atrial Fibrillation Stroke Calculator

I saw this link today on Facebook and thought I would share it – it is an AF Stroke Risk Calculator, and was posted by the Atrial Fibrillation Association – a great resource for people with atrial fibrillation. As you probably know one of the greatest risks of being afflicted with atrial fibrillation is that it can lead to you having a stroke. Blood clots can form in the malfunctioning atrium, break loose, travel to the brain and – BOOM!!!! – you’ve had a stroke. Prevention is the best approach.

This calculator is basically a clever automated version of the CHADS2 score. I was delighted to find my risk is 0%.

But if course my risk is definitely higher than zero percent – even if my CHADS2 score is zero.

My heart is abnormal in more ways than the atrial fibrillation. I have hypertrophy of my left ventricle (from running – not a risk factor) but I also have “severe hypertrophy” of my left atrium (the top chamber of the heart) which my cardiologist assures me is a risk factor for stroke and although my CHADS2 remains zero I am on an anticoagulant (Pradaxa).

My question has been: Why not include left atrial hypertrophy in the CHADS2 calculation?

Answer: I dunno.

My other question has been: What else can I do to reduce my risk of a stroke?

I understand my risk is NOT zero, regardless of what this calculator says.

Obviously one thing I know I can do is to remember to take my Pradaxa twice daily. Believe me, for somebody who is only taking one medication it isn’t as easy to remember as you might think. I have considered switching to Xarelto simply because of the once a day dosing.

pradaxasmall
My Pradaxa

But other than that what else can I do? One more thing (I think) – stay well hydrated.

As a large, slow, long distance runner (who is often on the trail for several hours at a time) I sweat more than smaller runners, and I have to be very careful not to become dehydrated. I spoke with a friend of mine who is an Internists/hospitalist and he agreed – don’t become dehydrated. Being dehydrated can literally thicken the blood and increase the chance on a clot, and therefore increase the chance of a stroke.

becareful
Be Careful Out There!

How much water should a person drink? I have no specific prescription but what I do is try to drink enough so that my urine is relatively clear once per day. Also there is such a thing as too much water and big, middle-aged distance runners are at relatively high risk of hyponatremia (too much water – not enough sodium) so be careful out there!

We talked about other risk factors are there? Risk factors for blood clots in the legs include being inactive, obesity, and smoking – probably less likely for the readers of this blog.

OLYMPUS DIGITAL CAMERA

What about alcohol? Does that increase the risk? He said probably not and in moderation might even decrease the risk – but remember – alcohol clearly increases your risk of atrial fibrillation – and if you drink enough alcohol you will become dehydrated – so there you go!

By the way – don’t expect this this risk calculator or this blog to advise you as to whether or not you should take your aspirin, your warfarin (Coumadin), your Xarelto, or your Pradaxa. It is important that you make this decision with your doctor.

Rejoice – Not All Runners in Atrial Fibrillation Are Slow

mooremtnhalfmarathon
Moore Mountain 1/2 Marathon

The thing I enjoy most about the afibrunner blog is comments from other athletes who are dealing with atrial fibrillation. A recent comment from a runner (we’ll call him “Lon”) really caught my attention – here is a runner who, while in atrial fibrillation, was able to race at six minute mile pace (or better).

Here are some excerpts from his comments:


Way to Go!!!
Since 1983 I’ve run/jogged 59 full marathons and have suffered with A-fib on and off for the last 12 years. I’ve finished the Boston (2001 in 3:23) and NY City (2005 in 4:15) marathons while in constant A-fib while carefully monitoring my heart rate. My cardiologists encouraged me to run marathons and also triathlons. One cardiologist told me that my heart is so strong that it laughs at A-fib and that I have the heart of an olympic cyclist. For the first 6 months of this year my heart was in constant A-fib that no drugs or multiple cardioversions could put it back into normal sinus rhythm. On July 9, 2013 I had the “Wolf Mini-Maze” (at the International A-fib Center of Excellence in Indianapolis) operation done on my heart. It was a great success and my heart has been in constant normal rhythm ever since (nearly 6 months now and I’m not taking any medications). In the Mini-Maze they removed my Left Atrial Appendage (LAA) so that if my heart ever goes back into constant A-fib I will NOT meed anticoagulant therapy. As you likely know life threatening blood clots tend to form in the LAA when your heart is in constant A-fib. The risk of stroke over the life time of an A-fib patient is huge. 3 out of 5 A-fib patients will suffer a stroke in their life even while taking anticoagulation meds like coumadin. That is a statistic that your doctor will not likely tell you about. Coumadin is over rated and is simply not very effective for some people which should be a terrifying realization to anyone dealing with A-fib. Anyway, as much as I love marathons, I’m laying off the long distance jogging for a while and am just jogging 10K’s (one per moth and 3 sprint triathlons this Summer) as well as several other physical activities.
Good health to you!
Lon

I have lamented that atrial fibrillation has made me slow, while openly admitting that I started out slow – I’ve only ran, as far as I know, one six minute mile in my entire life – and that was thirty years ago.

OLYMPUS DIGITAL CAMERA
Finish Line – Eugene Marathon

My understanding about atrial fibrillation is that the atria no longer preload the ventricles, and most people have a decrease of about 20% of their cardiac output. While sedentary people might not even notice this athletes certainly would. I do!

But I have heard that in some patients, certain athletes, there is little change in cardiac output and atrial fibrillation will not affect performance much. Lon seems like one of these fortunate people. Lon’s point about the increased risk of stroke (even if you take your Coumadin, Pradaxa, or Xarelto) is well taken – and I’m guessing that that is why he continued to pursue an effective treatment for his atrial fibrillation.

OLYMPUS DIGITAL CAMERA
Finish Line – Haulin’ Aspen Marathon

But after all those marathons Lon states he is no longer running endurance events – he goes on to elaborate:

Here’s a little more. I tried not to make a long story short above. I left out mentioning that I had a radio-frequency catheter ablation in June 2010 in Seattle that worked great in keeping my heart in normal rhythm until December 2012 when suddenly for no apparent reason went into persistent A-fib. (During that 2 1/2 year period I finished 9 full marathons and 8 sprint triathlons) My heart stayed in persistent A-fib even after 4 cardioversions and large doses of amiodarone. My cardiologists in Seattle told me that I should accept my persistent A-fib and they offered to ablate my hearts pace makers (AV and SA nodes) and give me an electronic pacemaker so that my heart rate can be controlled. That told me that I needed a second opinion so I started communications with Dr. Randall Wolf in Indianapolis about his Mini-Maze procedure. After consultations with an E.D. doctor (and a championship Iron Man triathlete) who had the Mini-maze operation and was very happy with the results, I decided to get the Wolf Mini-Maze and of course I informed my Seattle cardiologists of my intentions and they said to go for it. Absolutely the main reason that I went for the Wolf Mini-Maze is that it removes the left atrial appendage which brings my risk of stroke down to that of a healthy person with a normal healthy heart while not taking any anticoagulation drugs. The fact that I now enjoy a normal heart beat is just a huge plus factor.

From 1983 until December 2012 I completed 61 full marathons a most of which ran with all out efforts (I’ve averaged sub-6 minute pace all the way). I’m now finding out that long distance running is simply not good for the heart and most likely caused my A-fib problem.

Google Dr. John Mandrola’s 18 minute video called “Cycling Wed: I told you so…”. It is very illuminating and a must see for all endurance athletes. Please check that out.
Cordially,
Lon

I don’t know much about the Wolf Mini-Maze procedure and don’t necessarily advocate it for everybody, but clearly it worked in Lon’s specific situation. Here is some information regarding the Wolf Mini-Maze.

lakeofinish
Finish Line – Lake of the Woods 15K

No need to Google the video by Dr O’Keefe (posted on Dr Mandrola’s blog) I have the link right HERE.

Here’s the video:

If you don’t feel like watching the eighteen minute video I will summarize it for you – Exercise is good for you but in moderation. Too much or too intense exercise causes chronic inflammation of the heart and can ultimately harm the heart (atrial fibrillation, among other risks).

But if you are an endurance athlete dealing with atrial fibrillation you already know this – surely you have had a dozen or so friends and relatives, possibly sedentary and/or obese, kindly forward you information about the study he refers to – as if to justify their seemingly wise choice to avoid marathons and triathlons and replace it by watching other people play sports on television. Yes, this study was in all the newspapers and magazines last year.

avegiantsfinish
Finish Line – Avenue of the Giants Marathon

Please understand, and I paraphrase here, that Dr O’Keefe states that exercise is good for your heart, and being obese and sedentary is bad for your heart – but that overdoing it is a problem. He didn’t say people should avoid exercising.

My choice – I understand the concept of the “law of diminishing returns” as well as the next guy; but for me, well, I enjoy long, slow trail runs and mountain bike rides more than just about anything else I can think of – so I chose to continue.

Mountain Biking and Atrial Fibrillation

Mountain Biking in Oregon – Waldo Lake Trail

I’ve just returned from a nearly three-hour long mountain bike ride, so I thought it would be a good time to write about mountain biking while in persistent atrial fibrillation (this discussion is pertaining specifically to persistent A fib meaning I am always in atrial fibrillation and don’t ever expect to NOT be in a fib; I think people who have episodes of paroxysmal atrial fibrillation are going to have a different result).

One of my main concerns when I was first verified to have persistent atrial fibrillation was whether or not would be able to continue mountain biking. I started road riding in the early 80s, back when I still lived in the Midwest. When I moved to Klamath Falls, Oregon in 1987 I began mountain biking. This is a great place to ride, and we have a terrific trail system at Moore Park, as well as a couple of local high mountain singletrack trails that are legal for mountain biking (Brown Mountain Trail, Rye Spur Trail). I feel real connection to these trails and have been riding some of them for over twenty-five years.

ryespur

Rye Spur Trail, Klamath County, Oregon

I didn’t use to run is much as I do now, and back in the late 80s and early 90s I would pretty much mountain bike five or six days per week. I have developed some good bike handling skills, especially since in the early days there was no front or rear suspension, and nobody really knew what they were doing anyway. We pretty much plunged our quick release seat posts down into the frame, switched to granny gear as soon as we hit dirt, and would (inappropriately) lock up our back wheels and skid down steep hills – very much discouraged in this modern era. But that’s the way it was – skills develop over time.

yeti

One of my old mountain bikes

At any rate I have developed good skills – skills specific to these particular trails, seeing that I generally know every rock and anticipate every little drop off.

There are two issues with mountain biking and atrial fibrillation. The first, obviously, is that my cardiac output is reduced by about 15 or 20%, so naturally I am a little bit slower. People get slower when they get older, too, so there’s that to deal with as well. But the real issue, I think, is the fact that I am on a potent anticoagulant – Pradaxa. One of the disadvantages of Pradaxa is that it works really well (but the real disadvantages that it does not have a reversal agent). Clearly – there is a risk of bleeding associated with crashing your mountain bike on the trail.

I sort of doubt whether Coumadin is that much safer than Pradaxa as far as this is concerned – while it is true that there is a reversal agent for Coumadin, what is the likelihood that, if I had a major crash, I would be able to get to the emergency department in time for them to give me the reversal agent? I generally ride alone, and our trails are pretty remote. It would take a while for me to get out of there, especially if I was bleeding all over the place, or even worse, if I were bleeding into the space previously occupied by important parts of my brain.

Over the years my skills have improved and my style has changed quite a bit. At age 53 I’m no longer much of a daredevil (I never really was). Back when I was thirty and was riding about five days per week, I estimated that I had one minor crash per week, and usually one major crash per season. In all that time I think I’ve only actually hit my head once (I definitely recall a bleeding ear after crashing on a technical descent on a trail called Garbage – never liked that trail).

I have always felt that all of your instincts and reflexes are directed toward protecting the head. It’s automatic.

Of course I have worn a helmet when bicycling since 1983. I even bought a new helmet when I went into atrial fibrillation and started anticoagulation. It fits better than my old one and it’s florescent green, so hopefully I have less chance of being run over by a pickup truck.

The only time I have ever had a significant bleeding problem while mountain biking was back in 1990. I came off the trail ride and was heading around the paved road at Moore Park to the picnic area to get some water when some young guys in a pickup shouted at me, “Wrong way, dude!” I didn’t yell back at them, but I turned around and glared at them as I zipped down a little hill to the picnic area, giving them a look that said, “You talkin’ to me?” I was going pretty fast at that point and hit a speed bump that sent me skidding across the pavement for a while.

I bet those guys were impressed.

Anyway, I had a lot of road rash, was just goes with bicycling to a certain extent, but the worst thing was I had a “degloving injury” on the side of my abdomen. What that means is that part of my skin more or less stuck to the pavement while the rest of me kept moving and the skin was pulled away from the underlying tissue. It didn’t break all the way through the skin, but I developed a hematoma the size of a baseball right where the “love handle” would normally be. Twenty-three years later it’s actually still there to a certain extent, not the blood, but a big lump of scar tissue beneath the skin, and the skin over that area is still kind of numb.

OLYMPUS DIGITAL CAMERA

Klamath Ridgeview Trail – Moore Park

That happened with no anticoagulation – I never even took an aspirin back then. If I had a similar injury now that would’ve been a major hematoma – I might even need a transfusion.

That’s the risk. Falls are part of riding a mountain bike. I’ve been on Pradaxa for a year now and I think I’ve only had two crashes. I am so much more cautious than I used to be that I rarely ever crash, and when I do crash it usually something stupid like having mud or ice in my pedals and not been able to click out when stopping, falling over like Artie Johnson used to do on that tricycle on Rowan and Martin’s Laugh In. I honestly can’t say that I’ve noticed more bruising or bleeding than I would expect prior to Pradaxa. So far, so good.

I feel it is important, however, that when you’re cardiologist tells you that you probably shouldn’t be mountain biking that you do what he says. Don’t be like me. Don’t disregard your cardiologist advice. Do as I say, not as I do.

All joking aside – there is a certain risk and if you can accept that level of risk, then continue mountain biking. If not, stay off the trails.

As far as how much persistent atrial fibrillation affects my climbing, well, when I first get started it is quite difficult. After I warm up it really doesn’t seem like it’s any different than not be in atrial fibrillation. Recall that I do not take anything like a beta blocker or an antiarrhythmic – if you take medications like that your experience may definitely be different. All I take is the anticoagulant.

I’m slow, definitely slower than I was twenty-five years ago, but it almost seems like it’s within the realm of what you’d expect from being that much older. Like I said in the article about running in atrial fibrillation, it’s almost like you’re a pickup truck with a four speed manual transmission, but you can only use second and third gear. But you can still have a lot of fun in those two gears! It just takes a while to warm up.

Personally I think road biking is more dangerous than mountain biking, as far as bleeding risks are concerned. All my best crashes have been on pavement, including my best mountain bike crashes (see above). And pavement is usually where cars, driven by people who are talking or texting on smart-phones, hit you.

As far as endurance and energy output are concerned road biking, by its very nature, is easier to do in persistent atrial fibrillation that mountain biking. On a road bike you get into a groove, and have a certain steady energy output. That’s perfect for atrial fibrillation. Anybody who trail rides, especially on technical, steep trails, can tell you that mountain biking consists of a little burst of energy here, then a little short, brief period of rest and recovery here (by slow pedaling for a couple of seconds), and then hammering the pedals again to get over the next little obstacle, or whatever. That’s what’s fun about it – it’s almost like doing a puzzle. Trail riding involves a lot of little, short, anaerobic bursts of energy – and of course atrial fibrillation has diminished this ability, as far as I’m concerned.

Although, speaking strictly of endurance, I don’t think that is changed too much since I went into persistent atrial fibrillation. I can still ride for just as long as I used to be able to ride. I have found that while I have lost speed with age I have gained endurance in spite of atrial fibrillation.

I am very interested in other mountain bikers’ experiences with atrial fibrillation, especially athletes who take rate control or anti-arrhythmic medications. Please feel free to leave comments – Thanks!

Heat and Salt and A Fib

As stated previously I get pretty lightheaded when I get up from a sitting position after a hard workout, particularly in hot weather. Orthostatic hypotension. I don’t know why I get dehydrated so easily now, but I have learned that I need to eat something salty and drink a lot of water  after a workout, particularly a run or a bike ride which is longer than an hour or two, otherwise I get pretty dizzy when I first standup, and I’ve had a friend who is an nephrologist and another friend who is an internist both tell me to make sure I drink plenty of water after a workout and get some salt. Just one more fun aspect of being in persistent atrial fibrillation.

OLYMPUS DIGITAL CAMERA

Pre-Race Motel

This is the first time in my life I’ve ever actually been trying to get more salt. Most people spend their lives trying to avoid salt. I have started bringing potato chips for a post run snack to the trailhead for my long runs. Another great post run snack is some blue corn chips with some hummus with some Hoisin sauce.

OLYMPUS DIGITAL CAMERA

Pre-Race

Although it is neither here nor there, I’d like to state that I am a vegetarian (nearly vegan – if not for the occasional veggie pizza) as far as diet is concerned.

I also find that I am more sensitive to heat, which is obviously related. Last summer I would often start to feel pretty tired 17 miles into a 20 mile training run. In cool weather a 20 mile trail run is no problem. When I’m training for a 50K I basically try to do a 20 mile run every weekend.

Fortunately I live in Klamath Falls, on the East side of the Cascades of Oregon, where we have relatively cold Winters and generally cool Spring and Autumn. Summer, obviously, can be pretty hot – but nothing like Southern California, Arizona, Mexico, the South, etc.

Resting During a Trail Run

I have also noticed over the past several years that I did quite poorly during marathons if the weather got hot. The concept of hot weather is a relative term – for me anything over 70°F (21°C) would be considered hot. My ideal running weather would be 35 to 55°F. Ten years ago I could do a 20 mile run when it was 90°F (32°C) without much problem. Those days are over.

I’d be interested in hearing from other people with atrial fibrillation with respect to this. Please comment.

Ringo – Pooped Out After a Long Trail Run

Persistent and Intermittent Atrial Fibrillation

There are different types of atrial fibrillation. They’re all the same arrhythmia, the main difference is duration. Some people have intermittent (or paroxysmal) atrial fibrillation. This means that the individual goes into atrial fibrillation for a short period of time – maybe a couple minutes, maybe twenty-four hours, but less than one week. Most of the descriptions of atrial fibrillation I have found on the web describe paroxysmal atrial fibrillation.

Atrial fibrillation that lasts for longer than seven days is called persistent atrial fibrillation, and atrial fibrillation that lasts for over one year is referred to as long-standing persistent atrial fibrillation or permanent atrial fibrillation.

Regrettably that is the type of atrial fibrillation that I have. I have just “celebrated” my one year anniversary of persistent atrial fibrillation. I miss sinus rhythm.

twentysix

The Best Mile Marker

People who are in sinus rhythm most of the time and go into atrial fibrillation only occasionally are fortunate because they get to be in sinus rhythm most of the time, which is basically the hot set up for any type of endurance sports. The disadvantage is that when these individuals to go into atrial fibrillation the effects are pretty devastating, and more often than not they find themselves on their hands and knees wondering what happened. The other bad news for people with intermittent atrial fibrillation is that it may very well progress into a persistent type atrial fibrillation, and of course there is a risk of having a stroke. So it is important to discuss this and formulate an appropriate treatment plan with your healthcare provider.

The disadvantage of being in persistent, but relatively asymptomatic, atrial fibrillation is that you have a performance penalty all the time; but the advantage is that you stabilize, at least I have, and are able to participate in your sport, albeit at a slower pace. It never gets much worse or much better.

Maybe there are some athletes out there who are in persistent atrial fibrillation who are unable to continue to participate in running, mountain biking, etc. if so I would encourage you to share your stories in the comments section.

All unable to discuss at this point in time is my own personal experience.

Intro – Atrial Fibrillation and Endurance Sports

It turns out atrial fibrillation is pretty common in middle-aged endurance athletes. About a year ago, when I first went into persistent atrial fibrillation I was surprised to find out how common it was in athletes, but also surprised to find out there weren’t a lot of resources on the web. I am writing this blog in order to provide information about atrial fibrillation in athletes from an athlete’s point of view only.

My purpose is not to give medical advice. I am a podiatrist employed at Klamath Orthopedics and Sports Medicine and my practice is limited to the treatment of the foot and ankle – not the heart. Cardiology is not in my scope of practice.

Also – before you ask – I don’t plan to give podiatry advice in this blog, either.

I’m a 53-year-old distance runner and mountain biker who is in persistent atrial fibrillation. Persistent atrial fibrillation means that I do not go in and out of atrial fibrillation, like some athletes, I am always in atrial fibrillation and I am not expected to ever be out of atrial fibrillation. I am more or less asymptomatic, except for palpitations and, of course,  a slower pace, and do not take any specific treatment except for a blood thinner (Pradaxa).

I continue to enjoy marathoning, trail running, mountain biking, hiking, and any other outdoor activity for that matter. I am not sure how many marathons I have completed, but probably around fifteen. I have trained for two 50K runs, but was only able to run one of them. I was discouraged to participate in my first 50K by my electrophysiologist (more on that later). That was before he actually saw me as a patient.

Peterson Ridge Rumble 20 and 40 Mile Trail Run – a great race that allows dogs. Here is my dog, Ringo, at the starting line.

My most recent event was the Peterson Ridge Rumble, a 20 mile trail run in Sisters, Oregon. Upcoming events include Lake of the Woods 15K, Siskiyou Outback 15K, and then the Bizz Johnson 50K in October.

I have done at least one marathon and one 50K while in atrial fibrillation, but I suspect that I have been in atrial fibrillation for at least one other previous marathon. It’s likely that I’ve been going in and out of atrial fibrillation for the past several years, and that explains a lot.

In 1994 I had open heart surgery to repair my mitral valve. At that time I was mountain biking six days per week and had severe mitral valve regurgitation and severe left atrial hypertrophy and I had a repair – no artificial valve or a pig valve – I have all the original equipment. Unfortunately the left atrial hypertrophy never resolved and as a result I eventually ended up developing arrhythmias, including a lot of PVCs and PACs, and have ultimately go on into persistent atrial fibrillation. PVCs and PACs, otherwise known as premature ventricular contractions and premature atrial contractions, are generally benign, but quite annoying arrhythmias that everybody experiences from time to time.

I am not happy (or proud) to be in atrial fibrillation, but this is what I have to deal with. I was told that in my specific case an ablation procedure would likely have less than 30% chance of being successful, and even if it were successful it would probably not be successful for more than five years.

I was never a fast runner, even in my youth and I’ve always been a big, slow runner (6′ 3”, just under 200 pounds), but now I’m ridiculously slow. But running still brings me the same joy that it always has and I plan to continue.

What Is Atrial Fibrillation?

Atrial fibrillation is the most common heart arrhythmia in athletes. The best explanation of atrial fibrillation, in my opinion, is from the Athlete’s Heart Blog:

Atrial Fibrillation in Athletes (In a Nutshell)

One simple way of looking at it is to realize that when you are in atrial fibrillation the atria (plural of atrium –  the top two chambers of the heart which help fill the ventricles) are beating so fast it is as if they are not being at all, so in other words an individual who is in atrial fibrillation has had the misfortune of going from a four chamber heart to a two chamber heart. This reduces cardiac output to a certain extent, but does not necessarily exclude one from athletic activities. But it makes a runner who was previously a back of the pack runner into a runner who finishes right ahead of the people who are walking the race.

Pradaxa and CHADS2

The only specific treatment I take with respect to my atrial fibrillation is a blood thinner. I am on Pradaxa which for me, I believe, is a better choice than no anticoagulation, aspirin, or Coumadin (warfarin).

Some of my Pradaxa

One of the worst things that can happen to a person in atrial fibrillation is that blood clots can form in the atria (plural of atrial), and can then release and become lodged in the brain. Since the left atrium is not really beating, and in my case it is quite enlarged, blood tends to pool here and this is perfect conditions for forming a blood clot. When a blood clot becomes lodged in the brain that is called a stroke or a cerebral vascular accident (CVA) and should be avoided at all costs. I actually met two different people, in one week, that had had strokes secondary to atrial fibrillation, and both of them were in their 50s. Both of them, regrettably, were lackadaisical about taking their anticoagulant at the time of their CVAs. Having a stroke, if you survive it, is an extreme life-changing event – definitely something to be avoided if possible.

Some people do not take any blood thinner at all. If your CHADS2 score is zero this is an option. My CHADS2 score is technically zero, but because of my severe left atrial hypertrophy my doctors think it is best that I am anticoagulated, and I fully agree.

What is meant by a CHADS2 score? Here is a link that explains, quite well the CHADS2 score:

CHADS2 on Wikipedia

Basically you get one point each for having congestive heart failure (C), being hypertensive (high blood pressure) (H), being seventy-five years of age or over (A), being diabetic (D), and you get two points if you have had a previous history of a stroke (S2). And it even spells CHADS2!

So, for example, if you are a ninety-year-old diabetic with high blood pressure and congestive heart failure, and you have already had a stroke, your CHADS2 score is maxed out at six points. Yes, you should definitely be on a blood thinner.

If you are a forty year old non-diabetic, non-hypertensive cyclocross racer who has demonstrated episodes of atrial fibrillation, but have no other risk factors, then aspirin, or no anti-coagulation at all, could possibly be an option.

If you have atrial fibrillation is important that you discuss this with your doctor and listen to what he or she has to say. I’m not giving medical advice here, I’m just explaining the system.

If your CHADS2 score is one aspirin or an anticoagulant such as coumadin may be an appropriate choice. But if your CHADS2 score is one or more you may want to be an anticoagulant such as Coumadin, Pradaxa, or Xarelto. Again, is important that you discuss this and agree with your doctor.

There are four choices regarding anticoagulation, and the choices are 1.) no anticoagulation 2.) aspirin, 3.) Coumadin,  and 4.) The newer, more expensive, but more convenient anticoagulants such as Pradaxa, Xarelto, and Eliquis.

Coumadin is relatively inexpensive, but interacts with a lot of different medications as well as a lot of different foods. I am a vegetarian and I eat a lot of green leafy vegetables which would make Coumadin a difficult choice for me. Also when I previously took Coumadin for six months after my open heart surgery I was having migraine headaches nearly every day. I rarely have a migraine since I discontinued Coumadin nearly 20 years ago. I don’t take any other medications, but if you do take other medications there’s a good chance that Coumadin may interact with them as well. Coumadin also requires frequent blood tests in order to make sure your anticoagulated at the proper level. Pradaxa and Xarelto do not require any blood tests. The disadvantage, and this is a big disadvantage, is that Coumadin is reversible if you do develop a serious bleeding episode whereas Pradaxa and Xarelto, for all practical purposes are not. It is possible that Pradaxa and Xarelto may be reversible with dialysis; but how likely is that????

Pradaxa is taken twice daily, and Coumadin and Xarelto are once daily. My doctor put me on Pradaxa after I was shown to have persistent atrial fibrillation. I have been taking it for over a year and really have had no problems. I’ve crashed my mountain bike just a couple of times and really haven’t noticed much difference as far as bleeding or bruising is concerned. But these were low-impact crashes and I realize there are some real dangers associated with anti-coagulation. It is important that you discuss this choice with your own health care provider.

By the way – I am fully aware that there are a zillion commercials for suing the “bad drug” Pradaxa – but I am convinced, that for me, my diet, and lifestyle, Pradaxa is safer than Coumadin.
