Temporal changes in geographic disparities in access to emergency heart attack and stroke care: Are we any better today?

► Temporal changes in timely access to heart attack and stroke care are investigated. ► Timeliness of access to cardiac and stroke care improved from 1999 to 2010. ► Ninety six percent of the population had access to an ER within 30 min in both 1999 and 2010. ► Neighborhoods with poor access had the lowest median income and housing values. ► Areas with access within 30 min had lower mortality risks than those within 60 min.
