Effect of Socioeconomic Deprivation on the Population Risk of Incident Heart Failure Hospitalisation: an Analysis of the Renfrew/Paisley Study

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.
