What is the recommended aspirin dose in the STEMI protocol?

Explanation:
In STEMI, the goal is rapid platelet inhibition to limit clot growth. Aspirin achieves this by irreversibly blocking the enzyme that makes thromboxane A2 in platelets, reducing aggregation. To get the effect quickly, give a single high oral dose that’s chewed so it absorbs fast. The STEMI protocol specifies 324 mg by mouth as the loading dose, often achieved with four 81 mg chewables or a single tablet. Lower daily or maintenance doses (like 81 mg or 162 mg) won’t provide the rapid, full platelet inhibition needed acutely, and IV aspirin isn’t used in this setting. Therefore, 324 mg taken by mouth is the recommended dose.
