Effect of socioeconomic deprivation on the population risk of incident heart failure hospitalisation: an analysis of the Renfrew/Paisley Study.

摘要

BACKGROUND: There are few data describing the effect of socioeconomic deprivation on the risk of developing heart failure (HF). AIMS: To examine the relationship between socioeconomic deprivation and hospitalisation with HF over 20 years. METHODS: Between 1972 and 1976, 15,402 individuals, aged 45-64 years, residing in two towns in Scotland, underwent cardiovascular screening. We report hospitalisations with HF over the subsequent 20 years according to Carstairs deprivation category and Social Class. RESULTS: Following screening, 628 men and women (4.1%) were hospitalised with a primary diagnosis of HF. There was a gradient in the risk of HF hospitalisation with increasing socioeconomic deprivation (P=0.003). Of the most deprived individuals, 6.4% were hospitalised for HF compared to 3.5% of the most affluent group. Cox-proportional Hazard models showed that independent of age, sex and baseline risk factors for cardio-respiratory status, greater socioeconomic deprivation increased the risk of HF admission (P<0.001, overall). The adjusted risk of admission for HF was 39% greater in the most versus least deprived subjects (RR 1.39 95% CI 1.04-2.01; P=0.04). CONCLUSION: These data show a link between social deprivation and the risk of developing HF, irrespective of baseline cardio-respiratory status and cardiovascular risk factors.
