Clinical management of older, frail patients with atrial fibrillation. The proposal of a multidisciplinary working group

Atrial fibrillation (AF) is the most common arrhythmia in elderly people. Older patients with AF have several comorbidities and should be treated with complex therapeutic schemes. Arrhythmia complications are also common at an advanced age. Accordingly, AF can be considered a marker of frailty. Few indications can be found concerning the management of frail older subjects in current guidelines. The Frailty in Atrial Fibrillation Survey Study (FAST) was designed to overcome the gap of knowledge about this extremely vulnerable subset of patients. A multidisciplinary team composed by cardiologists, geriatricians and internists participated in the project. In a first phase, a survey was conducted aiming at clarifying specialty-related differences in definition and oral anticoagulant therapy (OAT) management of frail individuals. In the second phase, specific chapters were prepared about AF and frailty epidemiology, the network for the management of the arrhythmia, the diagnostic strategies for AF (including a minimum data set of tools derived from the geriatric multidimensional assessment), OAT and the choice between a rate or a rhythm control strategy. For each chapter, up-to-date evidence and current guideline recommendations were presented and discussed among the 47 Italian centers participating in the project. In the last phase of FAST, the results of the survey and the final draft of the chapters were merged into the present document. A lack of homogeneity in frailty definition existed. The integration among cardiologists, geriatricians and internists can represent the most effective tool to get through these differences improving the management of frail older patients.
