What does ST elevation indicate?

Explanation:
ST elevation signals acute injury to the heart muscle from ischemia due to a sudden blockage of a coronary artery, leading to transmural (full-thickness) infarction. This is the classic sign of ST-elevation myocardial infarction and prompts urgent reperfusion therapy (PCI or thrombolysis). Other conditions can alter the ST segment, but new ST elevation in the affected leads specifically points to an acute coronary occlusion rather than atrial fibrillation, stroke, or pulmonary embolism.
