Management of heart failure: similarities and discrepancies between the European Society of Cardiology and the American Heart Association guidelines

Abstract

Recommendations are the fundamental elements of guidelines and are especially significant when the amount of scientific data is expanding fast, as is the scenario of heart failure (HF). Beginning with the four pillars of treatment for HF with reduced ejection fraction, the main messages of the two most recent major HF guidelines, endorsed by the European Society of Cardiology (ESC) and the American College of Cardiology/American Heart Association/Heart Failure Society of America (ACC/AHA/HFSA), partially overlap. There are notable differences, in part due to the timing of recent publications, like the Universal Definition of HF and the EMPEROR-Preserved trial, and in part due to differing perspectives on the natural history of HF. Specific challenges, such as risk stratification and the use of implanted cardioverter-defibrillators for primary prevention in HFrEF patients with non-ischaemic aetiology, are approached from a variety of perspectives. The ACC/AHA/HFSA recommendations place increased attention on topics that are especially pertinent to the US context, such as the cost-effectiveness of medications and the impact of health inequalities on HF care. A comparison of guideline suggestions may assist readers get a better grasp of the ESC and ACC/AHA/HFSA guidelines and apply logical ways to their own practice, wherever in the world that may be. A comparison may also contribute to the harmonization of future guidelines’ recommendations by highlighting the reasons why certain areas have resulted to different recommendations while seemingly analysing the same published information.
