Stroke prevention drugs may help reduce dementia risk for atrial fibrillation patients


Barcelona, Spain – 18 March 2018: Clients with atrial fibrillation might decrease the danger of dementia by taking stroke avoidance medications, inning accordance with suggestions released online today in EP Europace1, a European Society of Cardiology journal, and provided at EHRA 2018.2 The global agreement file was likewise released in HeartRhythm, the main journal of the Heart Rhythm Society (HRS), and Journal of Arrhythmia, the main journal of the Japanese Heart Rhythm Society (JHRS) and the Asia Pacific Heart Rhythm Society (APHRS).

The professional agreement declaration on arrhythmias and cognitive function was established by the European Heart Rhythm Association (EHRA), a branch of the European Society of Cardiology (ESC); the Heart Rhythm Society (HRS); the Asia Pacific Heart Rhythm Society (APHRS); and the Latin American Heart Rhythm Society (LAHRS).

Heart rhythm conditions (arrhythmias), along with some treatments carried out to treat them, can increase the danger of cognitive decrease and dementia. The global agreement file was composed for physicians specialising in arrhythmias and intends to raise awareness of the dangers of cognitive disability and dementia and the best ways to decrease them.

The file mentions that atrial fibrillation is related to a greater danger for cognitive disability and dementia, even in the lack of obvious stroke. This might be due to the fact that atrial fibrillation is related to a more than two-fold danger of quiet strokes. The build-up of quiet strokes and the associated brain injuries with time might add to cognitive disability.

Stroke avoidance with oral anticoagulant drugs is the primary top priority in the management of clients with atrial fibrillation. The agreement file states that oral anticoagulation might decrease the danger of dementia.

Embracing a healthy way of life might likewise decrease the danger of cognitive decrease in clients with atrial fibrillation. This consists of not cigarette smoking and avoiding or managing high blood pressure, weight problems, diabetes, and sleep apnoea.

” Clients with atrial fibrillation might have the ability to decrease their danger of cognitive disability and dementia by taking their oral anticoagulation medication and having a healthy way of life,” stated Dr Nikolaos Dagres, lead author and expert, Department of Electrophysiology, Heart Centre Leipzig, Germany.

The file likewise examines the association in between other arrhythmias and cognitive dysfunction, consisting of post-cardiac arrest, in clients with heart implantable gadgets such as implantable cardioverter defibrillators (ICDs) and pacemakers, and ablation treatments.

Treatment of atrial fibrillation with catheter ablation can itself result in quiet strokes and cognitive disability. To decrease the danger, doctors must follow suggestions for carrying out ablation and for the management of clients prior to and after the treatment.3,4

The agreement file keeps in mind that doctors might believe cognitive disability if a client’s look or behaviour modifications– for instance, if consultations are missed out on. Relative must be requested for security info. If suspicions are validated, the agreement file suggests tools to carry out an unbiased evaluation of cognitive function.

The paper highlights spaces in understanding and locations for additional research study. These consist of, for example, the best ways to determine atrial fibrillation clients at increased danger of cognitive disability and dementia, the result of rhythm control on cognitive function, and the effect of heart resynchronisation treatment (CRT) on cognitive function.
