Long-Term Prognostic Benefit of Field Triage and Direct Transfer of Patients With ST-Segment Elevation Myocardial Infarction Treated by Primary Percutaneous Coronary Intervention

Direct transfer (DT) to the catheterization laboratory has been demonstrated to reduce delays in primary percutaneous coronary intervention (PPCI). However, data with regard to its effect on long-term mortality are sparse. The aim of this study was to investigate the effect of DT on long-term mortality in patients with ST-segment elevation myocardial infarctions treated with PPCI. A cohort study was conducted of 1,859 patients (mean age 63.1 ± 13 years, 80.2% men) who underwent PPCI from May 2005 to December 2010. From the whole series, 425 patients (23%) were admitted by DT and 1,434 (77%) by emergency departments. DT patients were younger (mean age 61 ± 12 vs 64 ± 12 years, p = 0.017), were more frequently men (86% vs 76%, p = 0.001), and had a higher proportion of abciximab use (77% vs 64%, p
