Describing the relationship between atrial fibrillation and frailty: Clinical implications and open research questions.

In the recent years a lot of attention has been gathered by the issue of frailty outside the boundaries of the geriatric medicine, for example in the field of cardiovascular medicine. Atrial fibrillation (AF) is known as a very common cardiological condition, often burdened by high level of clinical complexity. Aim of this narrative review is to examine the most relevant evidence about the relationship between frailty and AF, focusing also on its impact on clinical management and natural history of patients with this condition. Data reported underline how a relevant relationship exists between these two conditions, even though the burden of frailty among AF cohorts is still unclear. Frailty seems to affect the clinical management, even though no definitive data are yet available. Lastly, frailty significantly increases the risk of all-cause mortality but it's still unclear the impact on thromboembolic and bleeding events. Despite several data are already available, more research is still needed to fully elucidate the relationship between these two clinical entities.
