Frühe Implementierung der „Fantastic four“ bei Herzinsuffizienz mit reduzierter Ejektionsfraktion

The 2021 guidelines of the European Society of Cardiology for the diagnosis and treatment of heart failure recommend the early implementation of all four mortality-lowering drug classes for heart failure with reduced ejection fraction (HFrEF), i. e. angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor II blocker-neprilysin inhibitor (ARNI), betablocker (BB), mineralocorticoid receptor-antagonists (MRA), and sodium-glucose linked transporter-2 inhibitors (SGLT2i). This article aims to give a practical compendium supporting physicians to enable safe and efficacious treatment for patients with HFrEF.
