Abstract
PURPOSE: Both heart failure and its treatment with diuretics or SGLT2 inhibitors increase fall risk in older adults. Therefore, decisions to continue or deprescribe diuretics or SGLT2 inhibitors in older heart failure patients who have fallen are generally highly complex and challenging for clinicians. However, a comprehensive overview of information required for rationale and safe decision-making is lacking. The aim of this clinical review was to assist clinicians in safe (de)prescribing of these drug classes in older heart failure patients. METHODS: We comprehensively searched and summarized published literature and international guidelines on the efficacy, fall-related safety issues, and deprescribing of the commonly prescribed diuretics and SGLT2 inhibitors in older adults. RESULTS: Both diuretics and SGLT2 inhibitors potentially cause various fall-related adverse effects. Their fall-related side effect profiles partly overlap (e.g., tendency to cause hypotension), but there are also important differences; based on the currently available evidence of this relatively new drug class, SGLT2 inhibitors seem to have a favorable fall-related adverse effect profile compared to diuretics (e.g., low/absent tendency to cause hyperglycemia or electrolyte abnormalities, low risk of worsening chronic kidney disease). In addition, SGLT2 inhibitors have potential beneficial effects (e.g., disease-modifying effects in heart failure, renoprotective effects), whereas diuretic effects are merely symptomatic. CONCLUSION: (De)prescribing diuretics and SGLT2 inhibitors in older heart failure patients who have fallen is often highly challenging, but this clinical review paper assists clinicians in individualized and patient-centered rational clinical decision-making: we provide a summary of available literature on efficacy and (subclass-specific) safety profiles of diuretics and SGLT2 inhibitors, and practical guidance on safe (de)prescribing of these drugs (e.g. a clinical decision tree for deprescribing diuretics in older adults who have fallen).
