ABSTRACT

Objective To evaluate the effects of socioeconomic status on the distribution of cardiovascular risk factors and clinicaltreatments of patients with acute myocardial infarction in Beijing.Methods In Beijing, a prospective, muhi-center, registration study was carried out which including 800 patients who were consecutively hospitalized for ST-segment elevation acute myocardial infarction within 24 hours after event attack in 19 different hospitals in Beijing between November, 2005 and December, 2006.Indicators of socioeconomic status included self-reported personal income (＜500, 500-2000,＞2000 RMB/month), educational attainment (≤ 12 and ＞ 12 years) and status of medical insurance (yes/no).According to categories of education, patients were categorized into two groups of lower socioeconomic status and higher socioeconomic status. Differences of cardiovascular risk factors and clinical treatments were compared across the two groups respectively. Results Proportion of diabetes and hyperlipidemia in patients with higher socioeconomic status was much higher than that of patients with lower socioeconomic status (P＜0.05, P＜0.01 respectively). Patients with lower socioeconomic status were more likely to be smokers (P ＜0.05). The rates of receiving coronary angiography and PTCA were much lower in patients with lower socioeconomic status. Medical insurance and income were the most important two socioeconomic factors determining the use of PTCA. Conclusion Compared to patients with lowersocioeconomic status,patients with higher socioeconomic status had higher rates of hyperlipidemia and diabetes but lower smoking rate among cardiovascular risk factors. The rates of receiving interventional therapies were much lower in patients with lower socioeconomic status.
