Aspirin therapy in patients who have suffered an acute myocardial infarction reduces the risk of adverse events and mortality. Studies have demonstrated that aspirin can reduce this risk by 20% (Antiplatelet Trialists' Collaboration, 1994). National guidelines strongly recommend long-term aspirin for the secondary prevention of subsequent cardiovascular events in eligible older patients discharged after AMI (Antman, 2004; Antman, 2008; Anderson, 2007; and Smith, 2006).

The measurement period is one calendar year but the reporting period is 3 months as a calendar quarter; Q1 = Jan – Mar, Q2 = Apr – Jun, Q3 = Jul – Sep, Q4 is Oct – Dec.

Patients for whom there are missing or inaccurate data (e.g., arrival time, medication administration, etc.) are considered to have failed the measure; the total number of patients with missing or erroneous (e.g., a time of 03:69 or a date of 10/26/2035) data (i.e., measure failures) must be reported with the results of the measure.

Exclusion element guidance: 
The exclusion for patients who are clinical trial participants is limited to patients participating in a clinical trial for acute myocardial infarction (AMI), ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (non-STEMI), heart attack, or acute coronary syndrome (ACS), the same conditions as covered by the measure. Other clinical trials are not valid reasons for exclusions.
