Relative Risk: 1.9 (95% CI 1.8–2)
Lower socioeconomic status is associated with a nearly twofold higher incidence of sudden cardiac arrest, with a more pronounced disparity in younger individuals and in the US compared to Canada.
Reinier et al. (2011) conducted an observational in Sudden cardiac arrest (n=9,235). Lowest socioeconomic quartile vs. Highest socioeconomic quartile was evaluated on Incidence of sudden cardiac arrest (IRR 1.9, 95% CI 1.8-2.0). Living in the lowest socioeconomic quartile was associated with nearly double the incidence of sudden cardiac arrest compared to the highest quartile (IRR 1.9; 95% CI 1.8-2.0).
