Atrial fibrillation and cycling

[ColinJ]

All done! Everything went smoothly and my heart is back in rhythm.

Excellent news!

I‘ll still be on the anti-coagulants for at least three months so any outdoor cycling is off the menu for this season at least

Is that because you worry about the consequences of an injury in a crash or accident?

I felt the same when I was put on anticoagulants 14 years ago but eventually decided that the added risk of cycling is small and the benefits are huge.

I now wear a medical dog tag when out of the house and have filled in medical info accessible from my phone's lockscreen. Hopefully, paramedics would read that info on one or the other if I were found unconscious and bleeding heavily.

I have met quite a few other riders on anticoagulants for life and they have a similar approach.

Anyway, enjoy getting back on the bike outdoors when you eventually do.

Such as exercise

Several studies have found troponin levels above the reference range following both prolonged and short-duration physical activity (4). The fact that exercise can induce troponin concentrations that meet the biochemical criteria for acute myocardial infarction has sparked debate.

If it's exercised induced though - the levels will quickly subside. Well that's what I was told.

They take two blood samples 12 hours apart, and the diagnosis is in the way the troponin level changes as much as the level itself:

It is all in the link I gave

“As a result, troponin concentrations normalise within 24–72 hours after physical activity (9). In comparison, troponin levels can remain elevated for 4–12 days following a myocardial infarction (4). The prolonged half-life of troponin after a myocardial infarction is likely due to its simultaneous release from the necrotic cells as it breaks down. Since these processes occur concurrently, estimating the half-life of circulating troponins has been challenging. “

Mine was done 2 hours apart. As it increased on the 2nd test - I was admitted and treated as HA.
