Key result
Intensive BP control reduces probable dementia risk ~38% in non-advanced CKM, but not advanced CKM.
Why the study?
Whether cardiovascular-kidney-metabolic syndrome stage modifies the cognitive benefits of intensive blood pressure control remains unclear.
Does intensive blood pressure control reduce the risk of probable dementia in patients with hypertension and varying stages of cardiovascular-kidney-metabolic (CKM) syndrome?
RCT (n=8,563)
Does intensive blood pressure control reduce the risk of probable dementia in patients with hypertension and varying stages of cardiovascular-kidney-metabolic (CKM) syndrome?
Hazard Ratio: 0.62 (95% CI 0.46–0.85)
p-value: p=0.009 for interaction
Intensive blood pressure control reduces the risk of probable dementia in hypertensive patients with non-advanced CKM syndrome, but this cognitive benefit is not observed in those with advanced CKM.
Intensive BP control may reduce dementia risk only in non-advanced CKM; leaves open stage-specific effects pending prospective confirmation.
INTRODUCTION: Whether cardiovascular-kidney-metabolic (CKM) syndrome stage modifies cognitive benefits of intensive blood pressure (BP) control remains unclear. METHODS: This post hoc analysis of Systolic Blood Pressure Intervention Trial - Memory and Cognition in Decreased Hypertension (SPRINT MIND) classified participants into non-advanced CKM (Stage 2, n = 5,632) and advanced CKM (Stages 3-4, n = 2,931). The primary outcome was probable dementia; secondary outcomes included mild cognitive impairment (MCI) and probable dementia or MCI composite. Treatment effects were evaluated using Cox models and generalized linear models. RESULTS: In non-advanced CKM, intensive BP control reduced risks of probable dementia (hazard ratio [HR] 0.62, 95% confidence interval [CI] 0.46-0.85) and composite outcome (HR 0.74, 95% CI 0.62-0.89). No benefit was observed in advanced CKM (probable dementia: HR 1.15; composite: HR 0.97). Significant interactions between treatment and CKM stage were observed for probable dementia (p = 0.009). CONCLUSION: Among patients with hypertension and non-advanced CKM syndrome, intensive BP control was associated with lower risk of probable dementia, whereas no such benefit was observed in advanced CKM (see Graphical Abstract).

Wang et al. (2026) conducted an RCT in Hypertension and cardiovascular-kidney-metabolic (CKM) syndrome (n=8,563). Intensive blood pressure control was evaluated on Probable dementia (HR 0.62, 95% CI 0.46-0.85, p=0.009 for interaction). Intensive blood pressure control reduced the risk of probable dementia in patients with non-advanced CKM syndrome (HR 0.62; 95% CI 0.46-0.85), but not in advanced CKM (P=0.009 for interaction).
