Key result
High excess predicted heart/vascular age was positively associated with mild cognitive impairment (OR 2.98; 95% CI 1.72-5.15) in rural adults without baseline cardiovascular disease.
Why the study?
Cardiovascular disease and dementia disproportionately affect rural communities, making strategies to effectively communicate CVD risk to prevent these conditions a high priority.

Is high excess predicted heart/vascular age associated with mild cognitive impairment in rural adults without baseline cardiovascular disease?
Odds Ratio: 2.98 (95% CI 1.72–5.15)
High excess predicted heart/vascular age is strongly associated with mild cognitive impairment in rural adults, suggesting it could serve as a useful metric for communicating combined cardiovascular and dementia risk.
May support integrated CV-cognitive risk discussions in rural primary care; hypothesis-generating and requires prospective validation.
BACKGROUND: Cardiovascular disease (CVD) and Alzheimer's disease and related dementias (ADRD) disproportionately affect rural communities. Identifying strategies to effectively communicate CVD risk to prevent these conditions remains a high priority. OBJECTIVE: We assessed the relation between predicted heart/vascular age (PHA), an easily communicated metric of CVD risk, and mild cognitive impairment (MCI), an early manifestation of ADRD. DESIGN, SETTING, PARTICIPANTS: Data were from 967 rural West Texas residents aged ≥40 years without CVD at baseline (2009-2012) enrolled in Project FRONTIER, an ongoing, multi-ethnic cohort study on cognitive aging. MEASUREMENTS: MCI was diagnosed using the standardized consensus review criteria. PHA was calculated using the Framingham CVD risk equation. High excess PHA (HEPHA) was defined as the difference between PHA and chronological age >5 years. Logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI). RESULTS: At baseline, the mean age of participants (70% women and 64% Hispanics) was 55 years. Almost 13% had MCI and 65% had HEPHA. After adjusting for socio-demographic and health factors, HEPHA was positively associated with MCI (OR=2.98; 95%CI: 1.72-5.15). Among participants without MCI at baseline who returned for follow-up exam after three years (n=238), a three-year negative change in PHA was seemingly associated with reduced odds for MCI (OR=0.98; 95%CI: 0.96-1.01). CONCLUSIONS: In this study, PHA was positively associated with MCI, with improvement in CVD risk profile seemingly related to reduced odds for MCI. PHA may provide a low-cost means of communicating CVD risk in rural settings to prevent both CVD and ADRD.

Appiah et al. (2022) conducted a cohort in Mild cognitive impairment (n=967). High excess predicted heart/vascular age (HEPHA) vs. No high excess predicted heart/vascular age was evaluated on Mild cognitive impairment (MCI) (OR 2.98, 95% CI 1.72-5.15). High excess predicted heart/vascular age was positively associated with mild cognitive impairment (OR 2.98; 95% CI 1.72-5.15) in rural adults without baseline cardiovascular disease.
