Review: Management of Atrial Fibrillation in Older Adults
12 Oct, 2024 | 19:52h | UTCIntroduction: Atrial fibrillation (AF) predominantly affects adults over 65 years old and often coexists with multiple chronic conditions, polypharmacy, and geriatric syndromes such as frailty. Despite this, most randomized controlled trials and guidelines do not tailor recommendations specifically for older adults with these complexities. This review addresses the gap by synthesizing evidence and applying aging science principles to AF management, aiming to provide a framework that prioritizes patients’ goals across the spectrum of older adults—from fit individuals to those who are frail or at the end of life.
Key Recommendations:
- Individualized Care Approach: Clinicians should tailor AF management by considering patients’ comorbidities, frailty, and personal health goals. Tools like the Clinical Frailty Scale and comprehensive geriatric assessment can aid in assessing fitness and frailty.
- Screening for AF: Systematic population-level screening for AF in older adults has not conclusively shown a reduction in stroke incidence. Decisions regarding screening should be individualized, weighing the potential benefits and burdens.
- Lifestyle Interventions: For functional older adults, lifestyle modifications such as weight loss, moderate physical activity, blood pressure control, and alcohol avoidance are recommended to prevent and manage AF.
- Symptom Management: Use validated patient-reported outcome measures to assess and manage AF symptoms effectively, aligning treatment with patients’ experiences and quality of life goals.
- Rate and Rhythm Control:
- Fit Older Adults: Early rhythm control is preferred, with catheter ablation showing superiority over anti-arrhythmic drugs in maintaining sinus rhythm and improving quality of life.
- Multimorbid/Frail Older Adults: Treatment should be individualized, balancing the risks and benefits of anti-arrhythmic drugs versus catheter ablation.
- Heart Failure Coexistence: Catheter ablation is recommended over medical therapy for patients with AF and heart failure with reduced ejection fraction.
- Anticoagulation Therapy:
- General Recommendation: Direct oral anticoagulants (DOACs) are preferred over warfarin due to similar efficacy and lower bleeding risk.
- Multimorbid/Frail Older Adults: Apixaban is favored for its lower bleeding risk. Decisions should consider life expectancy and patient preferences.
- End-of-Life Care: De-escalation of anticoagulation may be appropriate when risks outweigh benefits or when it aligns with the patient’s comfort-focused goals.
- Left Atrial Appendage Closure (LAAC):
- Indications: LAAC is considered for patients with contraindications to long-term anticoagulation.
- Considerations: Procedural risks should be weighed against potential benefits, especially in frail older adults.
Conclusion: Implementing an individualized, goal-directed approach to AF management in older adults can enhance patient care by aligning treatments with patients’ health priorities and improving clinical outcomes. Recognizing the heterogeneity among older adults with AF, clinicians should adopt strategies that consider fitness, frailty, comorbidities, and patient preferences to optimize care across the aging spectrum.
