Myocardial infarction (MI) is defined as a clinical (or pathologic) event caused by myocardial ischemia in which there is evidence of myocardial injury or necrosis [1,2]. Criteria are met when there is a rise and/or fall of cardiac biomarkers, along with supportive evidence in the form of typical symptoms, suggestive electrocardiographic (ECG) changes, or imaging evidence of new loss of viable myocardium or new regional wall motion abnormality.
Initial care of the patient with suspected acute MI should include the early and simultaneous achievement of four goals:
●Confirmation of the diagnosis by ECG and biomarker measurement
●Relief of ischemic pain
●Assessment of the hemodynamic state and correction of abnormalities that may be present
