Management of heart failure in patients with kidney disease—updates from the 2021 ESC guidelines

ABSTRACT The wide overlap between the syndromes of chronic kidney disease (CKD) and chronic heart failure (HF) means that familiarity with the 2021 European Society of Cardiology guidelines is of importance to nephrologists. The common risk factors for the two syndromes together with the adverse cardiac structural remodelling associated with CKD means that many kidney disease patients experience breathlessness and fall within the HF phenotypes categorized in the guidelines. The management of HF is evolving rapidly leading to significant changes in the latest guideline iteration. The 2021 guidelines have changed from the 2016 version firstly by an increased focus on identifying the three phenotypes of HF to guide appropriate evidence-based management. Secondly, a new and simplified treatment algorithm for HF with reduced ejection fraction involving the rapid sequential initiation and up-titration of four ‘pillars’ of drug treatment—angiotensin-converting enzyme inhibitors or angiotensin-neprilysin inhibitors, beta blockers, mineralocorticoid receptor antagonists and now, thanks to convincing trial data, sodium-glucose co-transporter 2 inhibitors. Thirdly, guidelines for device therapy have been changed with down-graded advice on indications for primary prevention implantable cardioverter defibrillator therapy for patients with non-ischaemic HF and for cardiac resynchronization therapy with left bundle branch block (LBBB) and a QRS duration
