The latest American College of Cardiology/American Heart Association guidelines recommend primary percutaneous coronary intervention (PCI) in acute ST-elevation myocardial infarction (STEMI) patients within 90 minutes from presentation to the emergency room. For interhospital transfers, the most recent PCI guidelines recommend first medical contact-to-device times ≤120 minutes. Although PCI-capable hospitals have improved door-to-balloon times, many patients present to non-PCI-capable facilities and have been excluded from national quality measures. ⋯ In our single-center experience, 22 scene STEMI patients were diagnosed and appropriately triaged by EMS to our center for primary PCI. Our data show feasibility of an EMS-activated STEMI network over long distances with good reperfusion times.

: The American College of Cardiology/American Heart Association guidelines for ST-elevation myocardial infarction state that an electrocardiogram (ECG) should be performed on patients with suspected acute coronary syndrome upon presentation to the emergency department (ED) within 10 minutes. ⋯ : The Graff ECG triage rule identified almost all patients for whom the CCL was activated. Modification of the rule as proposed by Glickman added very little to the rule's sensitivity, while increasing the number of ECGs required at triage.

The strategy of prehospital activation by the emergency medical system (EMS) in patients with ST-elevation myocardial infarction (STEMI) has been poorly adopted among the US hospitals that currently offer 24/7 primary percutaneous coronary intervention. In this study, we report a single center experience after the implementation of this strategy. From 2008 to 2011, we identified a total 188 STEMI patients (age 65 ± 15 years) presenting via EMS for primary percutaneous coronary intervention. ⋯ ED 39 ± 14.6%; P = 0.004). Differences in DTB time and left ventricular ejection fraction remained significant after adjusting for differences in baseline characteristics. In conclusion, the prehospital activation strategy is largely effective and should be systematically adopted in the treatment scheme of STEMI patients to lower mechanical reperfusion times and reduce the potential for untoward clinical outcomes.

Despite the fact that studies have demonstrated cost-effectiveness of chest pain observation units (CPOUs) in emergency departments, they have not been widely implemented. Thrombolysis in Myocardial Infarction (TIMI) score is an easy and reliable tool, but none of the prior studies have used it for risk stratification in CPOUs. We propose to study the impact of CPOU using TIMI risk stratification model on the length of stay (LOS) and cost savings. ⋯ CPOU using TIMI score is an easy and reliable risk stratification tool for patients with chest pain in the emergency department and can significantly reduce the LOS, hence saving millions of dollars in this economic crisis.
