Abstract
Introduction: The aim of this study was to investigate the association between acetylcholinesterase inhibitor (AChEI) use and risk of ischemic stroke and death in people with dementia.
Methods: A cohort study of 44,288 people with dementia registered in the Swedish Dementia Registry from 2007 to 2014. Propensity score-matched competing risk regression models were used to compute hazard ratios and 95% confidence intervals for the association between time-dependent AChEI use and risk of stroke and death.
Results: Compared with matched controls, AChEI users had a lower risk of stroke (hazard ratio: 0.85, 95% confidence interval: 0.75–0.95) and all-cause death (hazard ratio: 0.76, 95% confidence interval: 0.72–0.80). After considering competing risk of death, high doses (≥1.33 defined daily doses) of AChEI remained significantly associated with reduced stroke risk.
Discussion: The use of AChEIs in people with dementia may be associated with reduced risk of ischemic stroke and death. These results call for a closer examination of the cardiovascular effects of AChEIs.
