Pulia M, et al. - Researchers assessed door-to-balloon (D2B) time and first medical contact-to-balloon (FMC2B) time for ST-elevation myocardial infarction (STEMI) in relation to emergency medical services (EMS) activation coupled with a 24-hour/day in-house interventional team (IHIT). Using a STEMI Data Registry, they extracted demographic, procedural, and outcome data for consecutive patients presenting with STEMI to Loyola University Medical Center. They retrospectively analyzed 190 of 223 consecutive patients presenting between April 2009 and December 2015. They found that already excellent D2B and FMC2B times were significantly improved by EMS activation of the cardiac catheterization laboratory in STEMI, even in the setting of a 24-hour/day IHIT.
