acute coronary syndrome

Acute coronary syndrome (ACS) encompasses a spectrum of clinical presentations resulting from myocardial ischemia, including ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina. Not to be confused with stable angina, which typically occurs predictably with exertion, ACS requires immediate assessment and intervention, particularly in the context of the Incident Command System (ICS) for coordinated emergency response. Recognizing the signs and symptoms of ACS is essential for timely transport to advanced medical care.
