Mortality from Acute Coronary Syndrome: Does Place of Residence Matter?

Background : Current evidence shows inequality in the outcomes of rural and urban patients treated at their place of residence. This study compared in-hospital mortality between rural and urban patients with acute coronary syndrome (ACS) to find whether there were differences in the outcome and received treatment. Methods : Between May 2007 and January 2018, patients admitted with ACS were included. The patients' demographic, clinical, and laboratory data, as well as their in-hospital medical courses, were recorded. The association between place of residence (rural/urban) and in-hospital mortality due to ACS was evaluated using logistic regression adjusted for potential confounders. Results: Of 9088 recruited patients (mean age =61.30±12.25 y; 5557 men [61.1%]), 838 were rural residents. A positive family history of coronary artery disease (P=0.003), smoking (P=0.002), and hyperlipidemia (P=0.026), as well as a higher body mass index (P=0.013), was seen more frequently in the urban patients, while the rural patients had lower education levels (P<0.001) and higher unemployment rates (P=0.009). In-hospital mortality occurred in 135 patients (1.5%): 10 rural (1.2%) and 125 urban (1.5%) patients (P=0.465). The Firth regression model, used to adjust the effects of possible confounders, showed no significant difference concerning in-hospital mortality between the rural and urban patients (OR, 1.57; 95% CI, 0.376 to 7.450; P=0.585). Conclusion : This study found no significant differences in receiving proper treatment and in-hospital mortality between rural and urban patients with ACS.
