Sodium-glucose co-transporter-2 inhibitors in the non-diabetic heart failure patient

Heart failure (HF) with reduced ejection fraction (HFrEF) is a global cause of morbidity and mortality with over 60 million estimated cases worldwide. The burden of HF care is expected to increase with an ageing population as evidenced by the fact that 80% of HF-related hospitalizations occur in those aged above 65. Given the significant morbidity and mortality associated with HFrEF, there is a need for new prognostic therapies that have an impact on morbidity and mortality. In February of 2021, the National institute for Health and Care Excellence (NICE) released new guidance on the utility of Dapagliflozin for the management of heart failure with reduced ejection fraction (HFrEF). NICE advocated that dapagliflozin is a viable treatment option in symptomatic HFrEF patients on optimal medical management. The current list price of dapagliflozin is around £36.59 per 28-tablet pack with an estimated annual cost of £476.98 equating to £6939 per quality-adjusted life year. The guidance was mainly based on evidence produced from the 2019 DAPA-HF trial. This demonstrated that in HFrEF population, the use of dapagliflozin led to a significant reduction in worsening HF events, cardiovascular, and all-cause death. In this article, we summarize the evidence base for sodium-glucose co-transporter-2 inhibitors in the non-diabetic heart failure patient.
