Objective This study is sought to: 1) determine the clinical validity of Framingham General Cardiovascular Risk Score (FGCRS) for dementia assessment; 2) examine the associations between cardiovascular diseases and the risk of dementia.

Background Evidence supporting cardiovascular diseases could increase the risk of dementia remains fragmented. A comprehensive study to illuminate the distinctive associations across different dementia types is still lacking.

Design/Methods A total of 432079 dementia-free individuals at baseline from UK Biobank were included. Multivariable Cox proportional hazard models were used to investigate the prospective associations for FGCRS and a series of cardiovascular diseases with all-cause dementia (ACD) and its major component, Alzheimer’s disease (AD) and vascular dementia (VaD).

Results During a median follow-up of 110.1 months, 4711 individuals were diagnosed with dementia. FGCRS was associated with increased risks across the dementia spectrum. In stratification analysis, high-risk groups have demonstrated the greatest dementia burdens, particularly to VaD. Over 74 traits, 9 adverse associations, such as chronic ischemic heart disease (ACD: HR=1.354; AD: HR=1.269; VaD: HR=1.768), atrioventricular block (ACD: HR=1.562; AD: HR=1.556; VaD: HR=2.069), heart failure (ACD: HR=1.639; AD: HR=1.543; VaD: HR=2.141), and hypotension (ACD: HR=2.912; AD: HR=2.361; VaD: HR=3.315) were observed. Several distinctions were also found, which atrial fibrillation, and cerebral infarction, and hemorrhage only associated with greater risks of ACD and VaD.

Conclusions By identifying distinctive associations between cardiovascular diseases and dementia, this study has established a comprehensive “mapping” that may untangle the long-standing discrepancy. FGCRS has demonstrated its predictivity beyond cardiovascular diseases burdens, suggesting potential opportunities for implantation.
