Reinforces what was already believed, rather than introducing something new.
In a prospective cohort of 10,321 individuals with established CVD, dementia risk increased progressively with CVD risk factor burden and number of affected vascular beds over a median follow-up of 10.1 years. The association was strongest for cerebrovascular disease (HR 2.09) and peripheral artery disease (HR 1.68) compared with coronary artery disease alone, supporting cardiovascular risk management as a potential dementia prevention strategy in this population.
Prospective single-center cohort study. Individuals with established cardiovascular disease; mean age 61±10 years, 27% female.. Intervention: CVD risk factor burden and vascular bed involvement (observational exposures, not interventions).. Compared with: Stratified comparison: 0–1 risk factors vs. 2, 3, 4–9 risk factors; 1 affected vascular bed vs. 2, 3 affected beds; coronary artery disease alone vs. cerebrovascular disease and peripheral artery disease.. n = 10,321. Single center (UCC-SMART cohort); location not specified in source text..
Dementia incidence: 296 events among 10,321 participants (median follow-up 10.1 years; IQR 5.0-15.7) Risk factor burden: HR 1.87 (95% CI 1.31–2.67) for 4–9 factors vs. 0–1 factors Vascular bed involvement: HR 1.90 (95% CI 1.05–3.43) for 3 affected beds vs. 1 bed

Clinicians managing patients with established CVD should recognize that CVD risk factor burden and multi-bed vascular disease are independently associated with elevated dementia risk. This supports intensive cardiovascular risk factor management in this population as a potential strategy to reduce cognitive decline, although the observational design does not prove causality or that risk factor modification will prevent dementia.

Aim. To determine how cardiovascular disease (CVD) risk factor burden and vascular bed involvement relate to the risk of dementia in individuals with established CVD.Methods. Participants were from the prospective, single-center UCC-SMART cohort study, recruited between 1996-2024. CVD risk factor burden was defined as the number of CVD risk factors present. The number of affected vascular beds was the count of coronary artery disease, cerebrovascular disease, and peripheral artery disease. Relations with all-cause dementia were estimated with Cox regression adjusted for confounders.Results. Among 10,321 participants (mean age 61±10 years; 27% female), 296 developed dementia during a median follow-up of 10.1 years (IQR 5.0-15.7). Dementia risk increased with higher CVD risk factor burden: compared with 0-1 risk factors, hazard ratios were 1.35 (95% CI 0.95-1.92) for 2 risk factors, 1.58 (95% CI 1.10-2.26) for 3 risk factors, and 1.87 (95% CI 1.31-2.67) for 4-9 risk factors. Compared with 1 affected vascular bed, the hazard ratios were 1.32 (95% CI 1.02-1.71) for 2 affected vascular beds and 1.90 (95% CI 1.05-3.43) for 3 affected vascular beds. Dementia risk was higher in participants with peripheral artery disease (HR 1.68; 95% CI 1.24-2.28) and cerebrovascular disease (HR 2.09; 95% CI 1.61-2.71) than in those with coronary artery disease.Conclusion. Higher CVD risk factor burden and involvement of multiple vascular beds are related to increased dementia risk in individuals with established CVD. These findings underscore the importance of stringent cardiovascular risk management as a potential strategy to lower dementia risk in this population.
