Insights
Intensive blood pressure lowering treatment may benefit cognitive health, particularly for those with favorable cardiometabolic and renal profiles. Further research is needed to confirm these findings on mild cognitive impairment risk.
Area of Science:
- Cardiology
- Neurology
- Nephrology
Background:
- Cardiometabolic and renal health profiles may influence cognitive benefits from intensive blood pressure (BP) lowering.
- Previous studies have not fully explored this interaction.
Purpose of the Study:
- To investigate whether participants with varying cardiometabolic renal health profiles experience comparable cognitive benefits from intensive BP-lowering treatment.
- To analyze the association between intensive BP management and cognitive outcomes across different health profiles.
Main Methods:
- Post hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT).
- Derived cardiometabolic renal health profiles using baseline glucose, cholesterol, kidney function (eGFR, ACR), and cardiovascular disease history.
- Categorized participants into favorable, intermediate, and poor profiles; assessed cognitive outcomes including probable dementia and mild cognitive impairment (MCI).
Main Results:
- 8162 participants included; intensive BP lowering showed a reduced risk of MCI in those with favorable profiles (adjusted HR 0.64).
- The largest absolute risk reduction for MCI was observed in the favorable profile group (adjusted ARD -3.05%).
- A significant interaction was found on the absolute risk difference (ARD) scale (p=0.039), but not for other cognitive outcomes or adverse events.
Conclusions:
- Intensive BP-lowering treatment demonstrated a trend towards greater absolute risk reductions for MCI in individuals with favorable cardiometabolic renal health.
- These exploratory findings require validation in future studies to confirm the impact on cognitive health across diverse patient profiles.
Background:
Whether participants with different cardiometabolic renal health profiles would derive comparable cognitive benefits from intensive blood pressure (BP)-lowering treatment remains underexplored.
Methods:
This post hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT) derived a cardiometabolic renal health profile based on baseline levels of fasting plasma glucose, non-high-density lipoprotein cholesterol, estimated glomerular filtration rate, urine albumin-to-creatinine ratio and history of subclinical and clinical cardiovascular disease. Participants were categorised into tertiles (favourable, intermediate and poor) based on the distribution of the risk-weighted profile. Cognitive outcomes included probable dementia, mild cognitive impairment (MCI) and a composite of the two.
Results:
A total of 8162 participants (mean age 67.8 years; 35.2% women) with complete baseline profile data were included. In exploratory tertile-based analyses, intensive BP-lowering treatment was associated with a lower risk of MCI among participants with favourable profiles (adjusted HR 0.64, 95% CI 0.48-0.86), with the largest absolute risk difference observed in this group (adjusted ARD, -3.05%; 95% CI, -4.85% to -1.24%) and a significant interaction on the ARD scale (p for interaction = 0.039). No interaction was observed for the other cognitive outcomes or adverse events.
Conclusions:
Intensive BP-lowering treatment tended to be associated with greater absolute risk reductions for MCI among participants with favourable cardiometabolic renal health profiles. These findings should be considered exploratory and require validation in future studies.
