STEMI

ST-Elevation Myocardial Infarction (STEMI) is a clinical syndrome defined by characteristic symptoms of myocardial infarction or acute myocardial infarction, commonly known as a heart attack. A heart attack occurs when blood stops flowing properly to part of the heart, injuring the heart muscle due to lack of oxygen. The most common way to determine if a person has had a myocardial infarction is through electrocardiograms (ECGs) that trace the electrical signals in the heart. ECG testing is used to differentiate between two types of myocardial infarctions based on the shape of the tracing. An ST section of the tracing that is higher than the baseline is considered to be a STEMI. A STEMI usually requires aggressive treatment in a timely manner to prevent permanent heart damage.

STEMI is treated by restoring circulation to the heart, called reperfusion therapy, and typical methods are angioplasty, where the arteries are pushed open, and thrombolysis, where the blockage is removed using medications.

The Early Management of Adults with STEMI

The EMS Authority staff participated in a STEMI Work Group co-convened by the American Heart Association and the California Department of Public Health, STEMI & Stroke Prevention Program. The work group developed the STEMI guidelines titled “Recommendations for the Early Management of Adults with ST–Elevation Myocardial Infarction (STEMI)”.
