In simple words: A heart attack affecting the bottom part of the heart, shown by a specific change on a heart tracing (ECG).

ST elevation (STEMI) myocardial infarction of inferior wall.This code describes a type 1 myocardial infarction specifically affecting the inferior wall of the heart, characterized by ST segment elevation on an electrocardiogram (ECG). It represents acute, full-thickness damage to the heart muscle in this region due to a complete blockage of blood supply, typically from a coronary artery thrombosis.

Example 1: A patient presents to the emergency department with sudden onset chest pain radiating to the left arm and jaw, shortness of breath, and diaphoresis.An ECG reveals ST elevation in the inferior leads, confirming the diagnosis of an inferior STEMI., A patient with a history of coronary artery disease experiences severe chest pain while exercising. An ECG performed by paramedics shows ST elevation in the inferior leads. The patient is transported to the hospital for immediate treatment of an inferior STEMI. , A patient undergoes cardiac catheterization for unstable angina. During the procedure, a thrombus is discovered in a coronary artery supplying the inferior wall of the heart, causing ST elevation on the ECG. This represents an iatrogenic inferior STEMI.

Documentation should include the symptoms, ECG findings (ST elevation in inferior leads), cardiac enzyme levels (troponin), and any associated conditions or complications. Imaging studies, such as echocardiography or cardiac MRI, may be necessary to assess the extent of myocardial damage.

** Distinguishing between STEMI and non-STEMI is critical for determining appropriate treatment strategies.STEMI generally requires more aggressive interventions, such as thrombolytic therapy or percutaneous coronary intervention (PCI), to restore blood flow quickly.
