BACKGROUND: Socioeconomic status (SES) as reflected by residential zip code status may detrimentally influence a number of prehospital clinical, access-related, and transport variables that influence outcome for @entity1 with @entity583 ( @entity583 ) undergoing reperfusion. We sought to analyze the impact of SES on in-hospital mortality, timely reperfusion, and cost of hospitalization following @entity583 . METHODS AND RESULTS: We used the 2003-2011 Nationwide Inpatient Sample database for this analysis. All hospital admissions with a principal diagnosis of @entity583 were identified using ICD-9 codes. SES was assessed using median household income of the residential zip code for each @entity1 . There was a significantly higher mortality among the lowest SES quartile as compared to the highest quartile (OR [95% CI]: 1.11 [1.06 to 1.17]). Similarly, there was a highly significant trend indicating a progressively reduced timely reperfusion among @entity1 from lower quartiles (OR [95% CI]: 0.80 [0.74 to 0.88]). In addition, there was a lower utilization of circulatory support devices among @entity1 from lower as compared to higher zip code quartiles (OR [95% CI]: 0.85 [0.75 to 0.97]). Furthermore, the mean adjusted cost of hospitalization among quartiles 2, 3, and 4, as compared to quartile 1 was significantly higher by  913,  2140, and  4070, respectively. CONCLUSIONS: @entity1 residing in zip codes with lower SES had increased in-hospital mortality and decreased timely reperfusion following @entity583 as compared to @entity1 residing in higher SES zip codes. The cost of hospitalization of @entity1 from higher SES quartiles was significantly higher than those from lower quartiles.
