Angiotensin Receptor-neprilysin Inhibitor Versus Renin-angiotensin System Inhibitor for Dementia Risk in Patients With Heart Failure

Abstract

Abstract: The authors report the impact of angiotensin receptor-neprilysin inhibitor (ARNI) versus renin-angiotensin system inhibitor (RASI) on the management and outcomes in dementia among heart failure (HF) patients as obtained from the real-life nationwide registry. In this study, HF patients between January 1, 2017 and December 31, 2019 were divided into 2 groups, including subjects receiving RASI and ARNI. The incidence rate of dementia was calculated with the unit of 1000 person-years. Cox proportional hazard model was applied for the examination of the hazard ratio, and also presented with 95% confidence interval. Between 2017 and 2019, RASI and ARNI cohorts contain 18,154 subjects. After adjusting with age, sex, comorbidities, and medications, ARNI cohort had a lower risk of dementia (adjusted hazard ratio = 0.83; 95% confidence interval = 0.72, 0.95) than RASI cohort. The authors concluded that use of ARNI was associated with a lower risk of new-onset dementia in patients with HF.
