            Background
            
              Driving time to a percutaneous coronary intervention (
              PCI
              )–capable hospital is important in timely treatment of acute myocardial infarction (
              AMI
              ). Our objective was to determine whether driving time from one's residence to a
              PCI
              ‐capable hospital contributes to
              AMI
              deaths. We conducted a cross‐sectional study of age‐ and sex‐adjusted mortality in census block groups to evaluate this question.
            
          
          
            Methods and Results
            
              We studied all (14 027)
              AMI
              deaths that occurred during 2008–2012 in Arkansas to assess the relationship between driving time from the population center of a block group (neighborhood) to the nearest
              PCI
              ‐capable hospital. We estimated standardized mortality ratios in block groups that were adjusted for education (population over 25 years of age who did not graduate from high school), poverty (population living below federal poverty level), population density (population per square mile), mobility (population residing at the same address as 1 year ago), black (population that is black), rurality (rural households), geodesic distance, and driving time. The median geodesic distance and driving time were 12.8 miles (interquartile range 3.6–30.1) and 28.3 minutes (interquartile range 9.6–58.7), respectively. Risks in neighborhoods with long driving times (90th percentile) were 26% greater than risks in neighborhoods with short driving times (10th percentile), even after adjusting for education, poverty, population density, rurality, and black race (
              P
              &lt;0.0001).
            
          
          
            Conclusions
            
              AMI
              mortality increases with increasing driving time to the nearest
              PCI
              ‐capable hospital. Improving the healthcare system by reducing time to arrive at a
              PCI
              ‐capable hospital could reduce
              AMI
              deaths.
