A close friend aged 69 recently died of a heart attack whilst out cycling. I have several other friends of a similar age who suffer with Atrial Fibrillation, mostly in their mid-late 60’s, though one friend is the same age as me (55) and has it. They are all lifelong regular cyclists.
Are cyclists more prone to heart problems than the general population or other sports people? Is there any research/evidence around the causes?
I didn’t find the right solution from the internet.
