Key result
Lower socioeconomic status is linked to ~55% higher IHD mortality, with a north-south gradient.
Why the study?
The association between socioeconomic status and ischaemic heart disease mortality in multiple western European populations during the 1990s was assessed to understand disparities.
Does lower socioeconomic status increase ischaemic heart disease mortality in western European populations?

Comparison
Lower socioeconomic status (educational level) vs higher socioeconomic status

Longitudinal observational study using registry data
Follow-up
During the 1990s

Does lower socioeconomic status increase ischaemic heart disease mortality in western European populations?
Relative Risk: 1.55 (95% CI 1.51–1.6)
Socioeconomic disparities in IHD mortality were present across western Europe in the 1990s, with larger disparities in northern compared to southern European populations.
Avendaño et al. (2005) conducted an observational in Ischaemic heart disease. Lower socioeconomic status vs. Higher socioeconomic status was evaluated on Ischaemic heart disease mortality (RR 1.55, 95% CI 1.51-1.60). Lower socioeconomic status was associated with higher ischaemic heart disease mortality compared to higher status (e.g., men aged 30-59: RR 1.55; 95% CI 1.51-1.60), with a north-south gradient.
