On 29 November, Chinese researchers published a paper in the Journal of the American Heart Association suggesting a link between early coronary heart disease (CHD) and dementia. The aim of the study was to assess the potential relationship between age at CHD onset and the development of dementia. This study aimed to examine whether younger onset age of CHD is associated with a higher risk of incident dementia.
Data were obtained from the UK Biobank, a large biomedical database and research resource with health records of about 500,000 adults. A total of 432,667 adults (mean age 57 years old) were included, of whom 11.7% had CHD. Compared with participants who did not have CHD, participants with CHD had higher risks of developing dementia from any cause, Alzheimer's disease and vascular dementia. Authors concluded that younger onset age of CHD is associated with higher risks of developing all cause of dementia, Alzheimer's disease and vascular dementia.
