How is emergency MI treated?

Although the immediate priority in managing acute myocardial infarction is thrombolysis and reperfusion of the myocardium, a variety of other drug therapies such as heparin, β-adrenoceptor blockers, magnesium and insulin might also be considered in the early hours.

Can you have an MI without ECG changes?

NSTEMI is diagnosed in patients determined to have symptoms consistent with ACS and troponin elevation but without ECG changes consistent with STEMI. Unstable angina and NSTEMI differ primarily in the presence or absence of detectable troponin leak.
