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 <0.0001). The DT group had a shorter median contact-to-balloon time (105 vs 122 minutes, p <0.0001) and a shorter time to treatment (185 vs 255 minutes, p <0.0001) compared with the emergency department group. Thirty-day and long-term mortality (median follow-up 2.4 years, interquartile range 1.6 to 3.2) were lower in the DT group (3% vs 6%, p = 0.049, and 9.4% vs 14.4%, p = 0.008, respectively). An adjusted Cox regression analysis proved that the DT group had an improved prognosis during follow-up (hazard ratio 0.71, 95% confidence interval 0.50 to 0.99). In conclusion, DT of patients with ST-segment elevation myocardial infarctions for PPCI was associated with fewer delays and improved survival. This benefit was maintained after long follow-up. This strategy should be emphasized in all networks of ST-segment elevation myocardial infarction care.
