Socioeconomic disparity in cardiovascular disease: Possible biological pathways based on a proteomic approach.

Background And Aims: Large social disparities in the occurrence of cardiovascular disease (CVD) have been documented but the underlying biological mechanisms are largely unknown. We investigated a panel of biomarkers linked to CVD to improve our understanding and quantify the biological pathways in socioeconomic disparity in CVD and their mediation through behavioural and biological risk factors.

Methods: We included 1142 participants from the Copenhagen City Heart Study aged 55-64 years.
