Background: Late presentation after ST-elevation myocardial infarction (STEMI) is associated with poor outcomes. However, contemporary data regarding management and outcomes of such patients are lacking. Methods: Using data from the ACTION Registry-GWTG, we identified 170,247 patients who presented with STEMI to 688 US sites, between 7/08 and 12/13. Patients were stratified according to time from symptom onset to presentation as timely presenters (<12 hours) and late presenters (≥12 hours). Baseline characteristics, management and in-hospital outcomes were compared between the groups. Among late presenters, temporal trends in reperfusion strategy were also examined. Results: A total of 9389 patients (5.5%) had late presentation and 160,858 (94.5%) had timely presentation. Late presenters were more frequently elderly, female and of non-White ethnicity (Table). Late presenters were less likely to have prior MI or prior revascularization, but more likely to have diabetes. Compared with timely presenters, late presenters had worse in-hospital outcomes including mortality (6.3% vs. 5.2%; p<0.0001). Over the 6-year study period, the proportion of late presenters decreased slightly (5.8 vs. 5.4% respectively; p=0.03), while the proportion of late presenters undergoing primary PCI increased from 65% to 71% (p<0.001). Over the same time-period, among late presenters, median time from symptom onset to presentation increased slightly, door to balloon time decreased, and in-hospital mortality remained unchanged (6.0% vs. 6.0%). Conclusions: In contemporary practice, a modest proportion of STEMI patients continue to present >12 hours after symptom onset. Despite increased use of primary PCI and reduction in door-to-balloon times, the unadjusted mortality remains high among late presenters. Continued efforts to educate the public in order to reduce the proportion of late presenters remains warranted.

Background ST-elevation myocardial infarction (STEMI) remains the second leading cause of death in Canada. Primary percutaneous coronary intervention (PCI) has been recognized as an effective method for treating STEMI. Improved access to primary PCI can be achieved through the implementation of regional PCI centres, which was the impetus for implementing the PCI program in an east Toronto hospital in 2009. As such, the purpose of this study was to measure the efficacy of this program regional expansion. Methods A retrospective review of 101 patients diagnosed with STEMI from May to Sept 2010 was conducted. The average door-to-balloon time for these STEMI patients was calculated and the door-to-balloon times using different methods of arrival were analyzed. Method of arrival was by one of three ways: paramedic initiated referral; patient walk-ins to PCI centre emergency department; or transfer after walk-in to community hospital emergency department. Results The study found that mean door-to balloon time for PCI was 112.5 minutes. When the door-to-balloon times were compared across the three arrival methods, patients who presented by paramedic-initiated referral had significantly shorter door-to-balloon times, (89.5 minutes) relative to those transferred (120.9 minutes) and those who walked into a PCI centre (126.7 minutes) (p = 0.047). Conclusions The findings suggest that the partnership between the hospital and its EMS partners should be continued, and paramedic initiated referral should be expanded across Canada and EMS systems where feasible, as this level of coverage does not currently exist nationwide. Investments in regional centres of excellence and the creation of EMS partnerships are needed to enhance access to primary PCI.

Background Randomized controlled trials indicate that acute ST elevation myocardial infarction (STEMI) patients have better clinical outcomes if rapid, complete and stable coronary artery patency can be achieved. The Queen Elizabeth II Health Sciences Center in Halifax, Nova Scotia (QEIIHSC) commenced a 24 hour PPCI program in November 2005. This real world study compares 2 year mortality in STEMI patients treated by PPCI versus patients treated by fibrinolysis with provisional rescue PCI within Nova Scotia, Canada. Methods This was a single center retrospective cohort study. All consecutive Nova Scotia, fibrinolytic and PPCI eligible STEMI patients presenting within 12 hours of symptom onset between July 1 st 2005 and June 30 th 2006 treated by PPCI at the QEIIHSC or fibrinolyis outside the QEIIHSC were included. The outcome measure was all cause mortality censored on June 30 th 2007. The crude and independent association between PPCI versus fibrinolysis on mortality was estimated using a Cox regression model. Results Data for 423 eligible patients (100% of cohort) comprised of 359/423 (85%) patients treated with fibrinolytics and 64/359 (18%) treated by PPCI were analyzed. The median follow-up was 1.4 years. The median (Q25 to Q75) door to needle times in the fibrinolytic group and corresponding door to balloon times in the PPCI group were: 0.5 (.3 to .9) and 1.5 (1.1 to 1.9) hours respectively. PPCI was associated with a consistent trend toward lower mortality versus fibrinolysis during hospitalization: 2/64 (3.1%) vs. 29/359 (8.1%), P=0.16 and at 30 days 2/64 (3.1%) vs. 32/359 (15%), P=0.12. This association was significant at 1 and 2 year follow-up: 2/64 (3.1%) vs. 41/359 (11%), P=0.043 and 2/64 (3.1%) vs. 45/359 (12%), P=0.027 respectively. This corresponded with an independent HR for 2 year mortality of: 0.1 (.01 to 0.8), p=0.03. Conclusion Initial data from the PPCI program at the QEIIHSC in Halifax, Nova Scotia indicates that PPCI was associated significant reductions in mortality versus fibrinolysis for real world patients presenting with STEMI. This mortality reduction was achieved in the early pilot phase of a PPCI program with evolving door to balloon timelines versus an established fibrinolytic program with acceptable door to needle timelines.
