Evolving AMI care, 2010.

The care of the patient with an acute coronary syndrome, specifically STEMI, continues to evolve. Although the goal of caring for any patient with STEMI is a D2B time of less than 90 minutes, research shows that every minute counts, and "time is muscle". Thus, even if a hospital has an acceptable D2B time, EMS on-scene and transport times must be minimized to ensure optimal treatment and recovery of a dying heart. All EMS systems should work with their destination hospitals to ensure E2B times are optimally lowered and aim for an E2B of under 90 minutes when possible. MOreover, a team approach to PCI activation involving both the paramedic and ED physician whenever possible appears to be the best way to decrease false activations and increase recognition of STEMI patients. As research into myocardial infarction and treatment continues, EMS personnel should expect more critical care transports of patients who have already received lytic therapy. The in-hospital care of patients with acute coronary syndromes continues to evolve, and similarly EMS care for ACS patients continues to change at an ever-increasing rate.
