IntroductionNational consensus guidelines recommend that ST-segment elevation myocardial infarction (STEMI) patients achieve a door-to-balloon time of < 90 min. We sought to determine if emergency physician initiated simultaneous activation of the cardiac catheterisation laboratory team and the on-call interventional cardiologist has any impact on reducing door-to-balloon-times at our hospital.MethodsA total of 72 consecutive STEMI patients were evaluated from January 2007 to December 2007. The emergency physician activated Code STEMI required concurrent activation of cardiac catheterisation personnel and the on-call interventional cardiologist by the emergency physician. These patients were compared with our staff cardiologist activated primary angioplasty protocol from January 2006 to December 2006 for 51 consecutive STEMI patients. The primary outcome was to measure median door-to-balloon time between both groups. Secondary end-points included the individual components of door-to-balloon times (i.e. door-to-ECG time), peak troponin-I level within 24 h, length of stay and all-cause in-hospital mortality.ResultsMedian door-to-balloon time decreased overall (112 vs. 74 min, p < 0.001). Of the three components of door-to-balloon time analysed, the ECG to cardiac catheterization laboratory time exhibited the largest area of improvement with 16 min absolute reduction in median door-to-balloon time. Median peak troponin levels (50 vs. 25 ng/ml, p < 0.001), and hospital length of stay (4 vs. 3 days, p < 0.01) decreased. We did not see any statistically significant difference in all-cause in-hospital mortality (p = 0.6).ConclusionsEmergency physician activation of the Code STEMI significantly reduces door-to-balloon time to within national standards of care, and length of stay in STEMI patients.
