Abstract 4500: Regional ST-Elevation Myocardial Infarction Systems Expand Access to Primary Percutaneous Coronary Intervention
Background: Primary PCI is the preferred method for reperfusion among STEMI patients if it can be performed in a timely manner in high volume centers. Availability is the major limitation as <25% of hospitals in the United States perform primary PCI. Recently, single center regional STEMI networks have published encouraging results.
Methods: We examined the prospective databases of two large regional STEMI networks which utilize identical standardized protocols and integrated transfer systems to determine if the benefits of primary PCI could be expanded to hospitals distant from the PCI center. The Minneapolis Heart Institute included 2266 patients from 31 hospitals (including 498 at the PCI Center, 1033 from 11 Zone 1 hospitals up to 60 miles away and 735 from 19 Zone 2 hospitals up to 210 miles away). The Iowa Heart Center included 1206 patients from 24 hospitals (including 710 at the PCI center, 267 from 10 Zone 1 hospitals up to 60 miles away and 229 from 13 Zone 2 hospitals up to 120 miles away).
Conclusions: Regional STEMI networks are effective in transferring STEMI for primary PCI in a timely manner. The benefits of primary PCI can be expanded to hospitals up to 210 miles from the PCI center using regional STEMI systems.
