Coronary heart disease, heart failure, and the risk of dementia: A systematic review and meta-analysis
Introduction: Cardiovascular risk factors are closely linked with dementia risk, but whether heart disease predisposes to dementia is uncertain. Methods: We systematically reviewed the literature and meta-analyzed risk estimates from longitudinal studies reporting the association of coronary heart disease (CHD) or heart failure (HF) with risk of dementia. Results: We identified 16 studies (1,309,483 individuals) regarding CHD, and seven studies (1,958,702 individuals) about HF. A history of CHD was associated with a 27% increased risk of dementia (pooled relative risk [RR] [95% confidence interval, CI]: 1.27 [1.07-1.50]), albeit with considerable heterogeneity across studies (I2 = 80%). HF was associated with 60% increased dementia risk (pooled RR 1.60 [1.19-2.13]) with moderate heterogeneity (I2 = 59%). Among prospective population-based cohorts, pooled estimates were similar (for CHD, RR 1.26 [1.06-1.49], nine studies; and HF, RR 1.80 [1.41-2.31], four studies) and highly consistent (I2 = 0%). Conclusion: CHD and HF are associated with an increased risk of dementia.
