Experts develop quality indicators for management and outcomes of adults with atrial fibrillation Management and outcomes of adults with atrial fibrillation are presented today at EHRA 2021, an online scientific congress of the European Society of Cardiology (ESC). The document is published in EP Europace, a journal of the ESC. Atrial fibrillation is the most common heart rhythm disorder, affecting more than 40 million people globally. Those with the disorder have increased risks of complications including stroke, heart failure and dementia, and are twice as likely to be admitted to hospital as their peers without the condition. The economic burden of atrial fibrillation is rising, mainly due to complications and hospitalisations. Effective therapies exist (e.g. to prevent stroke) but are not consistently used.
