Low socioeconomic status, including unemployment, illiteracy, and smaller living area, is significantly associated with increased mortality after acute myocardial infarction in Iran.
Highlights socioeconomic disparities in post-MI survival; hypothesis-generating for equity interventions, should not yet change practice.
BACKGROUND: Studies have shown an inverse relationship between socioeconomic status (SES) and mortality due to coronary heart disease (CHD). Little is known about this association in Iran. This study aimed to investigate whether mortality after myocardial infarction (MI) varies by SES. METHODS: In a retrospective study, 1283 MI patients who hospitalized in Tehran Heart Center from March 2005 to March 2006 were followed up in March 2008. Demographic, clinical and SES data were collected from case records and by telephone interviews. Multiple logistic regression analysis was performed to estimate the predictive effect of socioeconomic factors on outcome. RESULTS: In all 664 patients were studied. Of these, 500 patients were alive and 164 were dead due to MI (64 died at hospital and 100 died at home). The results of regression analysis showed that in addition to treatment (OR = 9.52, 95%CI 4.84-18.7), having diabetes (OR = 1.78, 95% CI 1.12-2.81) or hyperlipidemia (OR = 1.82, 95% CI 1.14-2.90), socioeconomic variables including living area in square per person (lowest level vs. upper level OR = 4.92, 95% CI 2.11-11.4), unemployment (OR = 3.50, 95% CI 1.50-8.13) and education (OR for illiterate patients = 2.51, 95% CI 1.00-6.31) were the most significant contributing factors to increased mortality after MI. CONCLUSION: Although the findings should be interpreted with caution, the study results indicated that socioeconomic variables were significant contributing factors to increased mortality after myocardial infarction. The underlying role of socioeconomic status on increased mortality after MI deserves further investigation.

Donyavi et al. (2011) conducted a cohort in Acute myocardial infarction (n=664). Low socioeconomic status (e.g., lowest living area per person) vs. Higher socioeconomic status (e.g., upper level living area per person) was evaluated on Mortality after myocardial infarction (OR 4.92, 95% CI 2.11-11.4, p=< 0.0001). Lower socioeconomic status, particularly having the lowest living area per person, significantly increased the risk of mortality after myocardial infarction (OR 4.92).
