Atrial fibrillation in the elderly.

Area of Science:

• Gerontology
• Cardiology
• Epidemiology

Background:

• Atrial fibrillation (AF) prevalence significantly increases with age, affecting two-thirds of individuals over 75.
• Elderly patients with AF frequently experience co-morbidities, leading to poorer quality of life, increased hospitalizations, and cardiovascular events.
• The annual mortality rate in patients over 75 with AF is 8%, with higher rates observed in women.

Purpose of the Study:

• To review current data on the epidemiology of AF in the elderly.
• To examine risk factors, bleeding and embolism scores, and disease progression in older adults with AF.
• To discuss the management approach for elderly patients diagnosed with atrial fibrillation.

Main Methods:

• Literature review of epidemiological data.
• Analysis of risk factors and prognostic scores for bleeding and systemic embolism.
• Synthesis of information on the clinical evolution and treatment strategies for elderly AF patients.

Main Results:

• AF prevalence and associated risks, including stroke, are high in the elderly population.
• Elderly individuals with AF exhibit a higher burden of co-morbidities, impacting prognosis and quality of life.
• Despite elevated stroke risk, elderly patients are paradoxically less likely to receive oral anticoagulation therapy.

Conclusions:

• Atrial fibrillation poses significant health challenges for the elderly, characterized by increased mortality, co-morbidities, and cognitive decline.
• The undertreatment of oral anticoagulation in elderly AF patients represents a critical gap in care, necessitating targeted interventions.
• A comprehensive approach is required to manage AF in older adults, addressing epidemiological factors, risks, and optimizing treatment strategies.
