If any of you AF sufferers also have sleep apnoea, I urge you to learn as much as possible about the interface of the two--it ain't good. Research in Europe and the USA is showing that undiagnosed sleep apnoea can be the cause of AF. Even if it isn't the cause of your AF, it's worth being screened for it, as prolonged sleep apnoea causes permanent changes in the endothelial cells (which make up the blood vessels) leading to left atrial overload and stress. Apnoea also interferes with anti-AF drug treatment, can promote AF recurrence after a successful ablation and--to top it off--promotes increased risk of stroke.
As I suffer from both, I have had to do my own research, and have felt betrayed by the NHS as neither my cardiologist nor the medic at the sleep disorders clinic mentioned any of this to me. The apnoea was downplayed as a mere annoyance with no severe effects. And this is despite the fact that I informed both medics that my mother suffered from AF and and apnoea and died of a stroke. I suppose the less they tell us, the less they have to do...and the less they have to spend.
