==[[Unstable angina / non ST elevation myocardial infarction overview | Overview]]==
==[[Unstable angina / non ST elevation myocardial infarction overview | Overview]]==
[[Acute coronary syndrome]]s ([[ACS]]) is a term that encompasses [[unstable angina]] ([[UA]]), [[non-ST-segment elevation myocardial infarction]] ([[NSTEMI]]) and [[ST-segment elevation myocardial infarction]] ([[STEMI]]). 


While all three usually result from [[atherosclerotic plaque rupture]] and subsequent [[thrombus|thrombus formation]] in one of the main epicardial coronary arteries, with subsequent inadequate blood supply to meet the oxygen and metabolic demands of the [[myocardium]]. Other possible etiologies of this imbalance such as coronary artery narrowing alone, [[coronary spasm]], or [[coronary dissection]].
==[[Unstable angina / non ST elevation myocardial infarction classification | Classification]]==


Unstable angina, [[NSTEMI]] and [[STEMI]] are distinguished pathophysiologically as to whether or not the [[thrombus]] is '''occlusive''' (as in the case of [[STEMI]]) or '''non-occlusive'''(as in the case of [[UA]] and [[NSTEMI]]). If an electrocardiogram ([[EKG]]) is performed at the time that an [[occlusive coronary artery thrombus]] is formed, it will usually show [[ST-segment elevation]] in the leads which correspond to the territory of [[myocardium]] in which blood supply has been disrupted (see [[ST Elevation Myocardial Infarction Electrocardiogram|Electrocardiogram]]). If an EKG is performed at the time that a [[non-occlusive thrombus]] is formed, it may or may not show signs of [[ischemia]](see [[Unstable angina / NSTEMI ECG|Electrocardiogram]]).

[[Unstable angina pathophysiology|Unstable Angina]] | [[Non ST elevation myocardial infarction pathophysiology|Non-ST Elevation Myocardial Infarction]]


Frequently, [[Unstable Angina]] and [[NSTEMI]] are indistinguishable on inital evaluation as these two conditions are at different spectrums of [[ischemia]].  If the ischemia is significant to cause myocardial damage, there will be an elevation of Cardiac biomarkers ([[CK-MB]] or [[troponin]]) and would be classified as an [[NSTEMI]](see [[Unstable angina / NSTEMI bio markers|Biomarkers]]).  Often, these may not be detected for up to 12 hours in the bloodstream, which emphasizes the need for thorough evaluation. <ref name="Anderson"> Anderson JL, Adams CD, Antman EM, Bridges CR, Califf RM, Casey DE Jr, Chavey WE II, Fesmire FM, Hochman JS, Levin TN, Lincoff AM, Peterson ED, Theroux P, Wenger NK, Wright RS.
