Recommendations represent the core messages of guidelines, and are particularly important when the body of scientific evidence is rapidly growing, as in the case of heart failure (HF). The main messages from two latest 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), are partially overlapping, starting from the four pillars of treatment for HF with reduced ejection fraction. Some notable differences exist, in part related to the timing of recent publications (most notably, the Universal Definition of HF paper and the EMPEROR-Preserved trial), and in part reflecting differing views of the natural history of HF (with a clear differentiation between stages A and B HF in the ACC/AHA/HFSA guidelines). Different approaches are proposed to specific issues such as risk stratification and implantable cardioverter defibrillator use for primary prevention in HFrEF patients with non-ischaemic aetiology. The ACC/AHA/HFSA guidelines put a greater emphasis on some issues that are particularly relevant to the US setting, such as the cost-effectiveness of therapies and the impact of health disparities on HF care. A comparison between guideline recommendations may give readers a deeper understanding of the ESC and ACC/AHA/HFSA guidelines, and help them apply sensible approaches to their own practice, wherever that may be in the world. A comparison may possibly also help further harmonization of recommendations between future guidelines, by identifying why some areas have led to conflicting recommendation, even when ostensibly reviewing the same published evidence. © 2022 European Society of Cardiology.

Transthyretin (TTR) is a tetrameric protein synthesized mostly by the liver. As a result of gene mutations or as an ageing-related phenomenon, TTR molecules may misfold and deposit in the heart and in other organs as amyloid fibrils. Cardiac involvement in TTR-related amyloidosis (ATTR) manifests typically as left ventricular pseudohypertrophy and/or heart failure with preserved ejection fraction. ATTR is an underdiagnosed disorder as well as a crucial determinant of morbidity and mortality, thus justifying the current quest for a safe and effective treatment. Therapies targeting cardiac damage and its direct consequences may yield limited benefit, mostly related to dyspnoea relief through diuretics. For many years, liver or combined heart and liver transplantation have been the only available treatments for patients with mutations causing ATTR, including those with cardiac involvement. The therapeutic options now include several pharmacological agents that inhibit hepatic synthesis of TTR, stabilize the tetramer, or disrupt fibrils. Following the positive results of a phase 3 trial on tafamidis, and preliminary findings on patisiran and inotersen in patients with ATTR-related neuropathy and cardiac involvement, we provide an update on this rapidly evolving field, together with practical recommendations on the management of cardiac involvement. © 2019 Published on behalf of the European Society of Cardiology.
