Impacto da transferência inter-hospitalar nos resultados da interven？？o coronária percutanea primária

background: delays resulting from the transfer to perform primary percutaneous coronary intervention (pci) have a negative impact on the benefits of the procedure. methods: prospective registry aimed at comparing the results of primary pci in patients with st-segment elevation myocardial infarction (stemi) admitted or transferred to an interventional cath lab equipped hospital. results: between february 2009 and december 2011, 319 patients were included in the study with mean age of 59.8 ± 12 years, 28.5% were female and 22.3% were diabetics. patients transferred for primary pci (n = 201) had longer door-to-balloon time (86.4 ± 26.6 min vs 69 ± 22.6 min; p < 0.0001), a non-significant decrease in st-segment elevation resolution (83.5% vs 90.4%; p = 0.18), final timi 3 flow (90.1% vs 94.1%; p = 0.30), myocardial blush grade 3 (74.3% vs 78.8%; p = 0.22) and angiographic success (90.1% vs 94.1%; p = 0.30), and a non-significant increase in major bleeding (2% vs 0.9%; p = 0.20) and hospital mortality (6.5% vs 4%; p = 0.29). conclusions: the referral of patients with stemi directly to an interventional cath lab equipped hospital is associated with shorter door-to-balloon time and non-significant improvement of reperfusion markers and mortality.
