Insights
Sacubitril/valsartan, a heart failure medication, was found to reduce dementia risk by 15% in patients. This meta-analysis alleviates concerns about cognitive side effects, supporting its use in heart failure populations.
Area of Science:
- Cardiovascular Medicine
- Neurology
- Pharmacology
Background:
- Sacubitril/valsartan (ARNI) is a key heart failure (HF) treatment.
- Concerns exist regarding ARNI's potential link to cognitive decline and dementia, specifically Alzheimer's disease, due to neprilysin inhibition.
- Patients with HF have an elevated risk of dementia.
Purpose of the Study:
- To evaluate the association between sacubitril/valsartan use and the risk of all-cause dementia in heart failure patients.
- To address concerns about potential cognitive risks of sacubitril/valsartan.
Main Methods:
- A systematic literature search was performed on March 23, 2025.
- Included studies compared sacubitril/valsartan to placebo, no treatment, or other HF medications.
- A random-effects model was used to pool risk ratios (RRs) and 95% confidence intervals (CIs).
Main Results:
- Six studies (101,074 participants, 2017-2024) were analyzed.
- Sacubitril/valsartan use was linked to a significant 15% reduction in all-cause dementia risk (RR=0.85, 95% CI: 0.74-0.98, p=0.02).
- Sensitivity and subgroup analyses confirmed the findings' robustness.
Conclusions:
- Sacubitril/valsartan is associated with a reduced risk of dementia in HF patients.
- These findings mitigate concerns about cognitive adverse effects.
- The study supports the continued use of sacubitril/valsartan as a foundational HF therapy.
Background:
Sacubitril/valsartan, an angiotensin receptor neprilysin inhibitor (ARNI), has become a cornerstone therapy for heart failure (HF) since its approval over a decade ago. However, concerns have emerged about potential cognitive risks, as neprilysin inhibition may contribute to the accumulation of amyloid-beta (Aβ) in the brain-a hallmark of Alzheimer's disease, the most common form of dementia.
Objective:
Given the already elevated risk of dementia in patients with HF and the widespread use of sacubitril/valsartan, this meta-analysis aimed to evaluate whether its use is associated with an increased risk of all-cause dementia in HF populations.
Methods:
A systematic literature search was conducted on 23 March 2025, to identify eligible studies comparing the risk of dementia in patients receiving sacubitril/valsartan versus those receiving placebo, no treatment, or other HF medications. Risk ratios (RRs) and 95% confidence intervals (CIs) were pooled using a random-effects model.
Results:
Six studies, comprising 101,074 participants and published between 2017 and 2024, were included in the meta-analysis. Treatment with sacubitril/valsartan was associated with a significant 15% reduction in the risk of all-cause dementia (RR = 0.85; 95% CI: 0.74-0.98; p = 0.02). Leave-one-out sensitivity and subgroup analyses confirmed the robustness of the findings.
Conclusions:
This meta-analysis suggests that sacubitril/valsartan is associated with a reduced risk of dementia in patients with HF, helping to alleviate previous concerns about potential cognitive adverse effects. These findings support the continued use of sacubitril/valsartan as a foundational therapy in this high-risk population.
