"Nothings going to happen unless you make it happen."


I'm not sure who is actually reading this blog or even if you find it interesting or not, with little feedback it can be difficult to know how well it is received. 
 
I'm certainly no expert and just write from my own experiences and what I have learnt by facing or overcoming certain problems as they occur, I hope by writing this blog to raise awareness on matters of the heart so others might consider their own health and fitness needs and seek medical attention, if needed, before letting things get out of hand ..... at the very least writing this stuff helps me to recall my recent medical history & achievements 😉.

My biggest concern of late has without doubt been Atrial Fibrillation (also known as AFib or AF) and its quite noticeable from my conversations that many 'non-hearties' have no idea what this actually is, despite it being a fairly common heart condition which could hit almost any adult, regardless if you have a pre-existing heart condition or not.

Atrial fibrillation is the most common erratic heart rhythm disturbance, affecting around 1.5 million people in the UK alone, however it is estimated that a further 500,000 remain undiagnosed due to a lack of awareness. It can affect any adult of any age, but it's more common in older people with more men than women suffering with this condition. Did you know that someone with AF is five times more likely to have a stroke than someone without AF, with a further risk of heart failure both are serious and potentially fatal conditions if left untreated - so it is certainly worth being aware.

Much of which follows (down to the hearts break line below) is copied from the highly informative Dr AFib website, a fantastic resource on this subject:

Understanding AFib Progression

Atrial fibrillation (AFib) is an erratic heart rhythm that happens because of an interruption in the heart’s regular electrical conduction pattern. The altered electrical signals cause the two upper sections of the heart, known as the atria, to lose their proper connection with the two lower chambers, called the ventricles.

AFib affects millions of people and often causes symptoms such as shortness of breath, fatigue, dizziness, chest discomfort, and weakness. If you have AFib, chances are you have experienced some or all these symptoms.

For some individuals, AFib will resolve by itself, but for others, it can grow into a long term if not a permanent problem. AFib is often a progressive condition for many people, meaning that the symptoms will increase in frequency and tend to last longer.

Unfortunately, restoring the heart’s natural rhythm, called a normal sinus rhythm, is difficult when AFib is present over a long period. As AFib worsens, managing it becomes challenging for both the individual suffering from it and their healthcare team.

Types of AFib

There are four different types of atrial fibrillation:

  • Paroxysmal AFib occurs without warning, lasts less than a week, and can resolve without any medical treatment.
  • Persistent AFib lasts longer than a week, can return to a normal rhythm on its own, or sometimes requires medication or intervention to correct.
  • Long-standing persistent AFib means that your condition lasts for at least a year and doesn’t stop without treatment.
  • Permanent or chronic AFib is not correctable with medication or a procedure such as electrical cardioversion or ablation. This type often requires that you take medication long-term to help control your heart rhythm and rate and reduce your chances of having a stroke.

How Does AFib Progress?

AFib often causes AFib, which means that when an episode occurs, it increases the chances that a recurrence will happen.

Over time, episodes can become longer and occur more often. This increased frequency is due to changes in the heart’s structure and electrical activity that AFib creates.

When AFib progresses, it usually changes from a type that can end on its own to a variety that is constant. As far as the impact on your health, the speed at which this transformation happens, which your physician refers to as the progression rate, is sometimes more important than the length of the incident.

In some cases, AFib moves from paroxysmal to a persistent variety. For people with a new onset of paroxysmal AFib, 10 to 20 percent will experience a progression to persistent AFib after one year.

One of my own Kardia Mobile AFib traces

According to a study in the British medical journal Heart from 2015, up to 25 percent of older people with other chronic conditions demonstrated a progression from paroxysmal AFib to a sustained form within 1.5 years. The article also reported that the rate of progress correlates with an individual’s heart rate and age.

Another study referenced in the June 2018 edition of the Journal of Hypertension indicates that people that have conditions such as an enlarged left ventricle and increased stiffness in the arteries are at higher risk of paroxysmal AFib developing into a permanent form.

Other diseases that contribute to AFib progression include coronary artery disease, high blood pressure, heart failure, sleep apnea, obesity, diabetes, and hyperthyroidism. Men also have a higher risk of AFib progression than women.

The rate of AFib progression also depends on how well you follow your prescribed treatment plan.

Slowing the Progression of AFib

If you have AFib, there are some initial self-care steps you can take to reduce the risk of AFib progression. Most of these changes are ones you can make that will improve your overall health such as:

  • Starting and maintaining a regular exercise program.
  • Following a heart-healthy diet that includes lots of fresh or frozen fruits and vegetables and keeping your intake of canned, processed, and packaged foods to a small amount.
  • Reaching and maintaining a healthy weight.
  • Avoiding monosodium glutamate, which will trigger AFib episodes.
  • Stopping your use of any tobacco products.
  • Limiting or abstaining from consumption of alcoholic and caffeinated beverages.
  • Checking with your physician before taking any over-the-counter cold medications or herbal supplements.

If AFib is persistent, medication therapy can help control your rhythm and rate to reduce the strain on the heart muscle. Standard categories of medications used for treating persistent AFib may include:

  • Antiarrhythmics such as flecainide and sotalol.
  • Rate control agents like atenolol and metoprolol.
  • Anticoagulants like warfarin, which help prevent stroke.
  • Antiplatelet medication such as aspirin and Plavix.

Synchronised cardioversion, which uses electricity to shock the heart back into a normal rhythm, is often used as a short-term solution.

According to a research study the June 2015 issue of the Journal of American College of Cardiology, catheter ablation is a practical choice for reducing the progression of the persistent forms of AFib.

For people with other heart-related issues who are candidates for open-heart surgery, a maze procedure is also an option. The technique is like catheter ablation and uses radio waves or intense cold to create a system of scar tissue that stops the transmission of irregular electrical signals.

The progression of AFib depends on many factors, such as your age when the first event occurred, your complete health history, lifestyle habits, and the type of AFib you have. These factors will dictate the treatment plan that your healthcare team designs for you.

Regardless of how little or how much your AFib progresses, it is important to consistently follow your treatment plan to ensure that you have the best possible outcome.

Parkrun turbo booster
I was first diagnosed with paroxysmal AFib during anesthesia for some minor surgery in June 2018 [see part 4.5] but I suspect it to be a result of my heart attack in Dec 2016 or CHD (coronary heart disease). My symptoms come and go at regular intervals and I'm doing my best to control it through exercise, medication and sensible eating/drinking (though this has fallen by the wayside a little through the Covid pandemic). I have been trying to determine what triggers each episode but there doesn't seem to be any clear-cut pattern with it starting and ending without warning, though most episodes seem to start while I'm at total rest or even sleeping. Reading up on the condition possible triggers are given as:

  • Diet
  • Alcohol
  • Caffeine
  • Sleep deprivation
  • Fatigue
  • Illness
  • Testosterone
  • Emotions
  • Exercise
  • Medication
  • Dehydration
  • Stress

So far since I started keeping records in May 2020 (18 months) when I invested in a KardiaMobile ECG reader, I have recorded 16 episodes each lasting between 4 hours to 96 hours with an average duration of 35.25 hours.

 
I only have the single lead Kardia but at around £100.00 it has been one of my best buys over the last few years. This device sits in your pocket and links to your smart phone so you can carry out an instant ECG wherever, whenever you feel symptoms and it was this that finally confirmed I have AFib ending a lot of doubt and uncertainty where several Holter ECG monitors from the hospital had failed to detect anything. I can now see it was because they were always between episodes, including a 7-day recording (those sticky pads do get itchy over that period of time! - see 'Parkrun turbo booster' picture above).


I am now able to accurately track the duration and frequency of each episode to try and determine if there is any change in my condition. When I look at my own AFib record (see chart above) I notice there were less & shorter episodes between July and Dec 2020 than now, at first, I just thought that maybe it was down to a deterioration in my condition but looking closer this is when I increased the distance I was running, typically 15-20km, in training for my charity Maidenhead half marathon challenge [see part 4.12] and I kept up the intensity for a fair while after. Since the summer this year the frequency and distances of my runs have declined as I at first concentrated more on shorter runs and then loss of motivation kicked in, the AFib episodes have become more frequent, almost predictable over this period which could be contributing to my lack of drive - it's a pity that I don't have the data before the half marathon training to see if there is an overall decline or if the extra running actually did make a difference to what now seems the norm. - so now I'm trying to decide should I be giving myself a kick up the backside and get out there for regular longer runs again or give-in to family pressure and reduce the amount I'm running?

I wrote in my last blog about being at a bit of a cross-roads in terms which direction to take next with regards to running, it now feels to be more like a roundabout as I can't decide what to do for the best and end up going around in circles. 
 
With AFib becoming a much more regular feature this leaves me in a permanent state of tiredness with a little anxiety thrown in and so motivation has become more difficult with the support that carried me through the early pre-Covid days not really returning, leaving me feeling frustrated and very much on my own. Any group runs are either inconvenient times or as in the Spade Oak (#itsalwayson) run which I took part, a bit too much for me to cope with at the moment. I could really use some moral as well as physical support but it can be difficult to plan ahead, when I decide go for a long run it can be at fairly last minute depending on if I'm feeling able, this makes trying to arrange a meet a bit difficult though I am planning to run the 'Attack the Attack' (route that led to my heart attack) on the 5th anniversary of my heart attack on the 28th December 2021 and have invited others to join me again (but as always due to AFib  #itmightnotalwaysbeon).

Distances (km) run in 2021 - red markers where I've recorded AFib

On one hand I have family telling me I'm doing too much and to cut back which would be an easy option but the benefits gained through running have been very clear with increased fitness levels and lowered heart rate, blood pressure, cholesterol, weight loss, reduction in medication and combined with excellent stress echo-cardiogram results and a more general positive feeling in myself, I really don't want to undo what ground I have made up.

I'm often told that 'my story' is 'inspiring', but to my mind it's not really that inspiring when the drive that keeps you going is fear, to prevent more serious health issue's and that is my bottom line motivation ...... It's the people who can keep going without that drive who are truly inspiring! 

Cardiac history & current medication


Throughout my blogs I have often praised the many people who have helped & supported me to overcome my many medical problems over the past few years, so it is with much sadness and regret that I heard that probably the first of these people, Rob the cardiac nurse from the rehab., who had a real positive influence on me at a time when my confidence was rock-bottom has recently suffered a severe stroke and is unexpected to make a full recovery. 
 
I first met him during my first rehab in 2013 and then again after my heart attack in 2017, then later again the same year on the London Bridges sponsored walk [see part 4.2] and more recently in my role as a charity trustee with Hearts & Souls. I'm pretty sure it was him who first reassured me that at least I now knew my condition to take the appropriate action while Joe public (he included himself) could be struck any time, it is so sad that this has now happened to him – I wish him all the very best for the future.

Merry Christmas and healthy new year to all my readers .... don't over indulge (too much)!



ADDENDUM 27/03/2022:

ATRIAL FIBRILLATION ASSOCIATION

Through the publication of this blog I have been introduced to the 'Atrial Fibrillation Association'. This is a UK registered charity focusing on raising awareness of AFib by providing information and support materials for patients and medical professionals involved in detecting, diagnosing and managing AF. 

At the time of this blog I was writing from my personal experience at the lack of general knowledge of the condition and was not familiar with this organisation which would appear to fulfill the exact points I laid out above ..... web site link.

The AF Association online forum – Health Unlocked: www.healthunlocked.com/afassociation


UPDATE 17/09/2023:

Since publishing this blog, my own condition has progressed some what. 

Early May 2022 I entered the 'persistent' stage for the first time, this lasted 2,104 hours (87.7 days) before I had my first DC cardioversion which was successful but only lasted 3.5 days before I returned to persistent AFib. In December I was started on a course of Amiodarone, an anti-arrhythmic drug but it took a second cardioversion in Jan 2023, after 4,112.5 hours (171.4 days), to get me clear of AFib. 

I was taken off the Amiodarone in May 2023 and have since had 5 episodes of Paroxysmal AFib each progressively lasting longer than the previous with the last ending yesterday after 115.5 hours (my longest episode outside persistent AFib).
 
In June 2023 I was given an 'Exercise Tolerance Test' and from this I have been diagnosed with Chronotropic Incompetence, this is generally defined as 'exercise intolerance' due to the inability to increase the heart rate adequately during exercise to match the cardiac output to metabolic demands and may explain my recent lack of motivation.



UPDATE 31/03/2024:

I went back into persistent AFib at the beginning of Oct 2023 and remained in AF for 74 days until my first AF ablation at Hammersmith hospital on the 14th Dec 2023. I flipped back into AFib just 8 days later and was to be given a DC cardioversion, but as I had missed my anti-coagulation that morning, this couldn't be carried out for another 4 weeks. Instead I was re-started back on Amiodarone and after 5 days after starting treatment reverted back to NSR (normal sinus rhythm) and have remained clear of AFib since, although I was reduced to half dose of Amuiodarone from the end of my 3 month blanking period.

I recently retired and within the first week suffered chest & jaw pains, typical symptoms of a heart attack, and had my 5th angioplasty for angina with 2 addional stents bringing the total to 6 stents in all. I am now suffering from post procedual haematona in my right forearm.


 
 
Some feedback to this blog:

"Thank you for sharing your well written and informative explanation of Atrial Fibrillation. It will be very helpful for newcomers here." - (AFib patient)

"Hi Peter you are right, people have no idea in general about afib, I've been told when during an afib episode and feeling really unwell, to stop been so negative, hmmm that will cure it , lol." - (AFib patient)

"Great blog Pete - thanks for sharing." - (AFib patient)

"You’ve had a horrible year. I have found that going into persistent AF in October has really brought me down. Had an ablation recently, but went back into AF after two days. Of course it is still the blanking period, but I have a feeling that Amiodarone might be the next step. Like you, it’s not something that I would want long term." - (Heart patient)

Heart Attack to 10K (part 4.1) - Getting FFITer and Harefield & Heartbreak hill revisited

Image
GETTING FFITer. (Phase VI – sustaining a healthy life-style ) "Nothings going to happen unless you make it happen." I already knew I had an enlarged prostate, but during early April 2017 that I noticed that I was having to visit the little chairboys room a bit more frequently and it was becoming more difficult to pass water. I thought this might be due to a change in medication so mentioned it to my GP on one of my many visits. This prompted the doctor to get a little more intimate with me than I was comfortable with as he gave my prostate a little tickle (you'll probably have to pay extra for that in a house of ill repute!) and he then referred me to the Urologist. A blood test showed my PSA ( Prostate-specific antigen, a protein released from the prostate gland into the blood stream) to be 6.2, this was cause for concern as anything over 4.0 could indicate the presence of cancer cells. Normally, I believe the next stage would be to go for a biopsy, thi

Heart Attack to 10K (part 1) - That fateful day.

Image
THAT FATEFUL DAY. (Phase I – heart attack) Being at a bit of a loose end and with nothing better to do during that dull period between Christmas and New Year (or the Plymouth Argyle & Cheltenham Town matches as my fellow Chairboys & girls would remember it), I decided to go for a walk in the local countryside around the rolling Chiltern hills. Overnight it had frozen, but the bright winter sunshine turned the early frost into a mist persuading me that it might make for some good atmospheric photographs. So, on Wednesday 28 th December 2016 (a date now etched into my brain) I drove out to Bledlow Ridge, parked the car in a side road just after mid-day and set out with my camera on a 6.8 mile walk that by the time I returned to the car would become an adventure I wouldn't forget in a hurry and ultimately have a dramatic change on my priorities and the way I live my life. I had been meaning to walk the Radnage area for some time and with the afternoon bright sunl

(Phase III – cardiac rehabilitation) the cardiac rehab team 21 st Feb 2017 and I start phase III of my cardiac event when attending the first of 6 weeks of cardiac rehabilitation classes, but this part of the story really began back at my heart assessment 3 weeks earlier. Besides receiving my pedometer and starting an obsession in counting steps [see part 2], a series of measurements were taken which have since become the base point for tracking my subsequent progress.  My heart rate was 59, blood pressure 153/96, weight 98.2 kg, height 177cm, BMI 31.34 and waist 107cm. The Cardiac Prevention and Rehabilitation Team set long term targets against these measurements – blood pressure <140/90, weight 58-78.3kg, BMI 18.5-25 and waist <94cm.

Heart Attack to 10K (part 4.23) - God bless the NHS

Part 4.23 - GOD BLESS THE NHS (Phase VI - sustaining a healthy life-style) "Nothings going to happ en unless you ma ke it happen." Just occasionally I like to write something other than about my heart condition, highlighting my appreciation, experiences or support received over the past 6 and a bit years, to this end I have already written special blogs covering Cardiac Rehab , FITT , AFib awareness and Parkrun . Today I would like to show my admiration and gratitude for the tremendous work & service given to me by the NHS , not just for my heart problems but for other aliments I suffered over the same period. Recently I have been reading a 'question & answer' social media platform where the question of health care in the USA gets heavily debated when compared to the UK and elsewhere with 'socialised healthcare' and I admit knowing very little what happens over the pond other than it being 'private' and driven by insurance with terminology su

  Part 4.20 - PERSISTING WITH PARKRUN (Phase VI - sustaining a healthy life-style) "Nothings going to happ en unless you ma ke it happen." I only intended to write another blog if there was something special or significant to write about; well, since the last blog in May my AFib (Atrial Fibrillation) has moved up a level to from paroxysmal to persistent which is a fairly significant change in lifestyle for me and as a result I would like to write my own tribute to just how important parkrun has been, especially through this period of relative inactivity as it has been the only bright spot during a period where I have become concerned about my of lack of exercise, but as crucially how it gave me the opportunity to progress my health and fitness drive soon after I completed both cardiac rehab and the Wycombe Wanderers FITT lifestyle programme in 2017, months after suffering a heart attack. Parkrun has become a constant feature throughout these blogs for nearly 5 years now. I

BACK HOME & DRAMA AT WHITE HART LANE (Phase II – home recovery) Not the New Year's Eve I had planned but I was home!! 4 to 6 weeks off work, no driving for a month, lots of rest, no lifting – welcome to phase II of a cardiac event. Sounds good but it soon becomes tedious, never mind at last I get to see those photos that had led to all this excitement in the first place [see part 1] and that was about it for the first week or so, sitting in front either the TV or computer or reading a jolly good book I got for Christmas about a tale of a Chairboy who missed that famous FA Cup run* with the odd excursion past a few neighbours houses and back mummified with my WWFC scarf wrapped tightly around my head to keep the cold air at bay. The instructions were simple enough, plenty of rest and start slowly with gentle short walks, a little light dusting etc. and gradually build up the pace and length of the walks and resume normal daily activities over the next 4 weeks. *

PART 4.4 - FALLING HEART RATE: FITTER OR HIBERNATION? (Phase VI - sustaining a healthy life-style) "Nothings going to happen unless you make it happen." I didn’t really have any intention to continue with this blog beyond the first year but like in real life, my fitness campaign keeps rolling on so must the chronicles (or so I’ve been told by my blog fan).   Picking up from where we left off, my next parkrun on 3rd Feb. became a bit of a ground breaking occasion. It all started like any previous – a combination of jogging and walking when feeling the onset of angina but suddenly at about 3km I picked up a fairly comfortable stride and managed to keep going for the next 1km without pulling up when a fellow runner saw how I was pushing myself and offered to help me to the finish line. We jogged the last 1km together and finished in 33:09, just 18 seconds behind my best time. At about 2km this was the longest distance I had ran non-stop since starting parkrun and having
