Multimorbidity in Older Adults with Atrial Fibrillation

Older adults with atrial fibrillation often have multiple comorbid conditions, including common geriatric syndromes. Pharmacologic therapy, whether for rate control or rhythm control, can result in complications related to polypharmacy in patients who are often on multiple medications for other conditions. Because of uncertainty about the relative risks and benefits of rate versus rhythm control (including antiarrhythmic or ablation therapy), anticoagulation, and procedural treatments (eg, ablation, left atrial appendage closure, pacemaker placement) in older patients with multimorbidity, shared decision-making is essential. However, this may be challenging in patients with cognitive dysfunction, high fall risk, or advanced comorbidity.
