Additional Info

• In the acute ACS patient the term NSTEMI is generally used. Once the MI has evolved, it is a non-transmural infarct as evidenced by the absence of Q waves on the EKG.
• If the diagnosis of ACS is indicated by history and ECG, the diagnosis of NSTEMI may be established if a biomarker of myocardial injury has been released (i.e., troponin elevation). If there is no evidence of biochemical marker release suggestive of myocardial necrosis in a patient with suspected ACS, they may be considered to have experienced unstable angina.
