ST elevation (STEMI) myocardial infarction of anterior wall
ICD-10 I21.0 is a used to indicate a diagnosis of st elevation (stemi) myocardial infarction of anterior wall.
I21.0 refers to ST elevation myocardial infarction (STEMI) of the anterior wall, a critical condition characterized by the blockage of blood flow to the heart muscle, specifically affecting the anterior wall. This condition typically arises from the rupture of an atherosclerotic plaque leading to thrombosis in the left anterior descending artery (LAD). Clinically, patients may present with severe chest pain, shortness of breath, and diaphoresis. The anterior wall is primarily supplied by the LAD, and ischemia can lead to significant myocardial damage if not promptly treated. Disease progression can result in complications such as heart failure, arrhythmias, or cardiogenic shock. Diagnosis is often confirmed through electrocardiogram (ECG) findings showing ST-segment elevation in the anterior leads (V1-V6) and elevated cardiac biomarkers. Timely intervention, including reperfusion therapy, is crucial to restore blood flow and minimize myocardial injury.

I21.0 specifically covers ST elevation myocardial infarction affecting the anterior wall of the heart, typically due to occlusion of the left anterior descending artery. It is characterized by ST-segment elevation on ECG and elevated cardiac enzymes.
I21.0 should be used when there is clear evidence of ST elevation myocardial infarction localized to the anterior wall, as indicated by ECG findings and clinical presentation. It is distinct from other codes that may represent non-ST elevation myocardial infarctions or infarctions in other regions.
Documentation must include ECG results showing ST elevation in the anterior leads, clinical symptoms consistent with myocardial infarction, and laboratory results indicating elevated cardiac biomarkers. Comprehensive clinical notes detailing the patient's presentation and treatment are also essential.
