What is a Non-STEMI characterized by?

Complete block in the coronary artery
ST segment elevation
ST segment depression or T wave abnormalities
High ventricular pressure

The correct answer is: ST segment depression or T wave abnormalities

A Non-STEMI, or Non-ST-Elevation Myocardial Infarction, is characterized by specific changes in the electrocardiogram that indicate a partial blockage of blood flow to the heart muscle rather than a complete obstruction. The hallmark of Non-STEMI includes ST segment depression or T wave abnormalities. These changes reflect a lack of sufficient blood supply to the heart tissue due to coronary artery narrowing or partial blockage, leading to ischemia that does not cause the distinct ST segment elevation seen in a STEMI. This is crucial in differentiating types of myocardial infarctions and guiding appropriate treatment strategies. Understanding this characteristic helps EMS and healthcare professionals assess and manage patients effectively during acute coronary syndromes.
