Low-income patients at higher risk of death after heart atta
Authors identified all adult patients who were admitted with STEMI and divided them in four quartiles based on the median household income of the zip code of the patient’s residence. Among 639,300 STEMI hospitalizations, 184,150 (35.1%) were lowest income residents and 123,815 (19.4%) were highest income residents.

Study findings include:
• The lowest income residents had higher all-cause mortality, length of stay, rate of invasive mechanical ventilation and lower inflation-adjusted cost compared to the highest income residents. The lowest income residents had an 11.8% rate of mortality and the highest income residents had a 10.4% mortality rate.
• Age: Lowest income residents tended to be younger (mean age of 63.5) compared to the highest income residents (mean age of 65.7).
• Gender: There were more females in the lowest income group (35.7%) compared to the highest income group (29.8%).
• Race/Ethnicity: Lowest income residents had highest proportion of black, Hispanic, native Americans patients and lowest proportion of white and Asian or pacific islander patients compared to the other groups.
• Location: The highest income residents had more hospitalizations in urban hospitals while the lowest income residents had more hospitalizations in rural hospitals compared to other groups.
• Cost Per Hospitalization: While the mortality rate for the lowest income residents was higher, the cost per hospitalization was lower compared to highest income residents ($26,503 compared to $30,540).

The study reveal significantly higher mortality rates for low-income residents hospitalized with ST-elevation myocardial infarction (STEMI) when compared to higher-income residents.
