Study Progress of the Influence of Atrial Fibrillation Treatment on Dementia

The renin-angiotensin-aldosterone system (RAAS) therapy is not only beneficial to prevent AF but is also beneficial to prevent dementia. [...]patients with a high risk of AF (heart failure and hypertension) as well as those who already suffered from AF are recommended to receive RAAS therapy. In recent years, several randomized trials have shown that in the prevention of recurrent and symptomatic AF, catheter ablation was superior to antiarrhythmic therapy. Since AF is an independent risk factor for dementia, catheter ablation should have beneficial effects in patients with dementia. [...]the number of microembolic signals correlated with a subtle, diffuse postprocedural impairment of neuropsychological function. [...]catheter ablation reduced the progression of dementia in AF patients, and the need to reduce microemboli during ablation is significant. Furthermore, the RACE study showed that a higher resting heart rates was not associated with adverse outcomes. [...]the guide recommended that a resting heart rate of
