Introduction - Acute Coronary Syndromes


Patients presenting acutely unwell secondary to compromised myocardial blood supply are said to be suffering from an acute coronary syndrome (ACS). Based on clinical findings, ECG abnormalities and blood test analysis, acute coronary syndromes can be divided into three categories, ST elevation MI (STEMI), non ST elevation MI (NSTEMI) and unstable angina (UA) which, as you will now learn, broadly correlate with underlying pathological findings. The ECG plays a central role in first of all identifying patients with an acute coronary syndrome and in subsequently allocating them to a particular category of ACS. The latter, in turn, is the main factor determining their treatment.
