Abstract Aims The evidence are not conclusive that a small incremental increase in door-to-balloon (D2B) time leads to a significant increase in death of ST-elevation myocardial infarction (STEMI) patients. In a previous study, we described a quality improvement intervention that reduced D2B time in 333 patients with STEMI. The aim of the current study was to compare mortality rates of the patients, before and after the intervention. Methods and results We examined the survival of 133 consecutive patients with STEMI treated prior to an intervention to decrease D2B time and 200 treated after the intervention. The mortality rate was the same before and after the quality intervention. The median D2B time for the entire cohort was 55 min. The number of patients with D2B time >55 min prior to the intervention was 82/133 (61%) and after the intervention 74/200 (37%) P < 0.00001. Thirty-day mortality among the patients with D2B time ≤55 min was 5/178 (2.8%) and among those with D2B time >55 min was 15/155 (9.7%), P < 0.008. The hazard ratio for 30-day mortality when the D2B time was >55 min was 3.7 (1.3–10.4). Conclusion Mortality and non-fatal complications did not differ significantly between STEMI patients before and after a quality improvement intervention. However, the number of patients treated within 55 min from arrival was significantly higher after the intervention; and coronary intervention within this time was associated with a lower death rate.

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.
