Description
This measure is used to assess the percentage of emergency department (ED) patients 18 years and older with acute myocardial infarction (AMI) or chest pain who received aspirin within 24 hours before ED arrival or prior to transfer.
Rationale
The early use of aspirin in patients with acute myocardial infarction (AMI) results in a significant reduction in adverse events and subsequent mortality. The benefits of aspirin therapy on mortality are comparable to fibrinolytic therapy. The combination of aspirin and fibrinolytics provides additive benefits for patients with ST-segment elevation myocardial infarction. Aspirin is also effective in patients with non-ST-segment elevation myocardial infarction. National guidelines strongly recommend early aspirin for patients hospitalized with AMI.
