Non ST Elevation Myocardial Infarction NSTEMI

Total loss of coronary blood flow results in a clinical syndrome associated with what is known as ST segment elevation AMI (STE AMI). Partial loss of coronary perfusion if severe also can lead to necrosis as well—which is generally less severe and is loiown as NSTEMI (non-ST-elevation myocardial infarction), and other events of still lesser severity may be missed entirely or called angina, which can range from stable to unstable.

Unstable Angina (UA) and Non-ST-Segment Elevation Myocardial Infarction (NSTEMI) are important situations which may cause SCD or ML Treatment is aimed at the prevention of these events, mainly by revascularization after the immediate medical treatment. In this section, the medical therapy will be separately discussed for the hospital care and posthospital discharge care. 

ACS can be classified into UA, myocardial infarction (Ml) without ST-segment elevation [non-ST-elevation Ml (NSTEMI)], or STEMI. The presence of cardiac troponin in ACS indicates worse prognosis than the absence of troponin (9).
