The impact of modifiable risk factors in the association between socioeconomic status and sudden cardiac death in a prospective cohort study: equal access to healthcare, unequal outcome
Authors' conclusion
We observed an inverse association between both income and education and the risk of SCD, which was only in part explained by common cardiac risk factors
