BACKGROUND: China has had an increasing number of angina patients and deaths; over the last 30 years it has also seen an increase in the income gap between rich and poor. The impact of socioeconomic status (SES) on survival of Chinese people with angina is unclear.

METHODS: In 2001-03 we interviewed 1457 people aged ≥ 60 years in Anhui, China, having characterised socio-demographics and risk factors for cardiovascular disease and documented doctor-diagnosed angina at baseline. Their vital status was followed up over 5 years. A Cox regression model was used to calculate hazards ratio (HR) of mortality in relation to SES.

RESULTS: Mortality was higher among 131 angina patients (23.7%) than those without angina (14.2%); multivariate adjusted hazards ratio (HR) was 1.82 (95% CI 1.22-2.71). Compared to non-angina patients with a high level of income, occupational class or education, the adjusted HR for mortality among angina patients with corresponding low levels of these factors was 2.88 (1.38-4.22), 2.15 (1.11-4.17) and 2.41 (1.40-5.92) respectively.

CONCLUSIONS: The findings suggest an interaction between socioeconomic deprivation and angina on mortality in older Chinese. Inequalities need to be taken into account when implementing intervention programs.

Learning Objectives:
1. Identify the growing number of angina patients worldwide, and in particular in China. 2. List some correlates of socioeconomic status in China. 3. Describe the relationship between socioeconomic status and survival in angina patients in China. 4. Discuss the possible reasons for this relationship.

Presenting author's disclosure statement:

Qualified on the content I am responsible for because: As a medical student at Oxford University, I have already authored 2 peer-reviewed papers. I have a keen interest in the field of cardiology - I am a committee member of Oxford's 'Osler Cardiology Society' where I regularly lecture students. Although I grew up in the UK, I have connections through relatives in China and I had the opportunity to access data from this cohort study. This allowed me to formulate the current study proposal.
