Patients with active symptoms of acute coronary syndrome (ACS) should be instructed to call emergency services (eg, 911 in the United States), and they should be transported by emergency medical services personnel, not by themselves, family, or friends. Patients should be instructed to go to the emergency department immediately if the suspected ACS symptoms last longer than 20 minutes at rest or are associated with near syncope/syncope or hemodynamic instability.
