Insights
Atrial fibrillation (AF) increases stroke risk significantly. Early diagnosis and management of AF are crucial for reducing associated morbidity and mortality.
Area of Science:
- Cardiology
- Neurology
Context:
- Atrial fibrillation (AF) is a common arrhythmia linked to increased risks of cerebrovascular disease, heart failure, and mortality.
- Patients with non-valvular AF have a significantly higher incidence of ischemic stroke (approximately 5% annually) compared to those without AF.
- AF accounts for a substantial proportion of all ischemic strokes, highlighting its clinical importance.
Purpose:
- To provide healthcare professionals with evidence-based recommendations for managing patients with atrial fibrillation.
- To standardize the diagnosis, risk stratification, and treatment of AF based on current evidence.
- To guide the identification of thromboembolic risk and outline preventive strategies and timely referral protocols.
Summary:
- This guide offers standardized recommendations for the diagnosis and identification of patients with atrial fibrillation.
- It details risk stratification and treatment strategies tailored to AF classification, including thromboembolism prevention.
- The guide provides treatment protocols to ensure prompt referral for appropriate patient management.
Impact:
- Implementing these recommendations can decrease morbidity and mortality associated with atrial fibrillation.
- Standardized care pathways will improve the management of AF patients, leading to better health outcomes.
- Timely diagnosis and intervention are crucial for mitigating the severe consequences of atrial fibrillation.
Abstract:
Atrial fibrillation (AF) is associated with long-term increase in the incidence of cerebrovascular disease, heart failure and mortality. The incidence of ischemic stroke in patients with non-valvular atrial fibrillation averages 5 % per year, from two to seven more frequent than in patients without atrial fibrillation (AF). One in six ischemic stroke occurs in patients with AF. The detection and accurate diagnosis and timely therapeutic intervention have shown a decrease in morbidity and mortality associated with this arrhythmia. The above data by themselves justify the development of a management guide and care for these patients. The purpose of this guide is to provide health professionals recommendations based on the best available evidence with the intent to standardize actions: diagnosis and identification of patients with atrial fibrillation; risk stratification and treatment according to the classification of atrial fibrillation; identification of the risk of thromboembolism and its prevention; and treatment guidelines to determine which patient will require to be referred promptly.
