Aspirin Use Evidence and Resources
A substantial body of evidence shows that taking aspirin can help patients lower their risk of heart attack or stroke. Patients with heart disease or who have had a stroke in the past are at high risk for having a heart attack or another stroke. Taking an aspirin every day can help these patients lower their risk. For patients with heart disease, including those who have angina or have been treated for blocked arteries, taking aspirin can prevent them from having a heart attack. For those who have already had a heart attack or stroke, aspirin use can prevent another heart attack or stroke.
What PCOR Evidence Did EvidenceNOW Use?
Here are the PCOR findings used by EvidenceNOW for aspirin use:
In 2011, the American Heart Association (AHA) and the American College of Cardiology Foundation (ACCF) used PCOR evidence to develop guidelines on aspirin use in patients with heart disease and others who are at risk of heart attack or stroke.
Recommendation: Based on the evidence, the panel recommended long-term, low-dose aspirin therapy (75 to 100 mg daily) for patients with heart disease. For patients intolerant or allergic to aspirin, clopidogrel (75 mg daily) can be used as an alternative.
How Did EvidenceNOW Evaluate Whether Practices Followed This PCOR Evidence?
The measure used by EvidenceNOW to evaluate aspirin use reflects the percentage of patients with heart disease (including those with angina and those who have been treated for blocked arteries), patients with a history of a heart attack, and patients with a history of a stroke who use aspirin or a similar drug.
The National Quality Forum also endorsed this measure (NQF 0068), which is used by the Centers for Medicare & Medicaid Services. (Measure ID: CMS 164)
The EvidenceNOW goal for primary care practices in the study is to have at least 70 percent of patients for whom aspirin use is recommended be taking it or a similar drug.

AHA/ACCF Secondary Prevention and Risk Reduction Therapy for Patients with Coronary and Other Atherosclerotic Vascular Disease: 2011 Update
This is a clinical guideline, published in Circulation in 2011, for prescribing aspirin for secondary prevention of heart disease. This guideline was a key patient-centered outcomes research finding disseminated to clinicians participating in EvidenceNOW.
