Abstract

BACKGROUND: Aspirin is a well-established therapy for the secondary prevention of cardiovascular events. However, its role in the primary prevention of cardiovascular disease is unclear, especially in older persons, who have an increased risk. METHODS: From 2010 through 2014, we enrolled community-dwelling men and women in Australia and the United States who were 70 years of age or older (or ≥65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or disability. Participants were randomly assigned to receive 100 mg of enteric-coated aspirin or placebo. The primary end point was a composite of death, dementia, or persistent physical disability; results for this end point are reported in another article in the Journal. Secondary end points included major hemorrhage and cardiovascular disease (defined as fatal coronary heart disease, nonfatal myocardial infarction, fatal or nonfatal stroke, or hospitalization for heart failure). RESULTS: Of the 19,114 persons who were enrolled in the trial, 9525 were assigned to receive aspirin and 9589 to receive placebo. After a median of 4.7 years of follow-up, the rate of cardiovascular disease was 10.7 events per 1000 person-years in the aspirin group and 11.3 events per 1000 person-years in the placebo group (hazard ratio, 0.95; 95% confidence interval [CI], 0.83 to 1.08). The rate of major hemorrhage was 8.6 events per 1000 person-years and 6.2 events per 1000 person-years, respectively (hazard ratio, 1.38; 95% CI, 1.18 to 1.62; P<0.001). CONCLUSIONS: The use of low-dose aspirin as a primary prevention strategy in older adults resulted in a significantly higher risk of major hemorrhage and did not result in a significantly lower risk of cardiovascular disease than placebo.

  • For people >70 years of age (with or without diabetes), the balance of aspirin appears to have greater risk than benefit.

    “For people >70 years of age (with or without diabetes), the balance appears to have greater risk than benefit (179,181).”

    The Abstract Conclusions report that, for primary prevention in older adults, aspirin increased major hemorrhage without significantly reducing cardiovascular disease. The Methods and Results include diabetes as a subgroup and report no evidence of a differential cardiovascular effect. The claim omits the trial’s important limitation to generally healthy people without established cardiovascular disease; it should not be extended to everyone over 70. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Two other large randomized trials of aspirin for primary prevention, ARRIVE (in people without diabetes) and ASPREE (in the elderly, 11% with diabetes), found no benefit of aspirin on the primary efficacy end point and an increased risk of bleeding.

    “Two other large, randomized trials of aspirin for primary prevention, in people without diabetes (ARRIVE [Aspirin to Reduce Risk of Initial Vascular Events]) (180) and in the elderly (ASPREE [Aspirin in Reducing Events in the Elderly]) (181), in which 11% of participants had diabetes, found no benefit of aspirin on the primary efficacy end point and an increased risk of bleeding.”

    The Conclusions report more major hemorrhage without a significant reduction in cardiovascular disease, and the Results report no evidence that the cardiovascular or bleeding effects differed by diabetes subgroup (page not provided). But the trial studied aspirin for primary prevention in largely healthy older adults, not all people over 70; the paper notes that aspirin’s benefits can outweigh hemorrhage risk in secondary prevention. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In ASPREE, the rate of major hemorrhage per 1,000 person-years was 8.6 events versus 6.2 events (HR 1.38 [95% CI 1.18-1.62]; P < 0.001).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
