Aspirin before bed may reduce morning heart attack, stroke risk

USA Today reports that according to a study presented at a recent American Heart Association meeting, “taking the aspirin before bed may reduce the chance of having a heart attack or stroke in the morning.” According to USA Today, study author Tobias Bonten of the Leiden University Medical Center in the Netherlands explained, “Platelet activity is highest in the morning, and that is also the time that most heart attacks and strokes occur, so if you reduce platelet activity during the morning hours, you might reduce heart attacks and stroke at that time.”

The New York Times reports in its “Well” blog that Bonten said, “I think in most Western countries, people take aspirin in the morning. It’s already one of our most effective medications. But maybe we can improve it a little bit more by switching the time.”

These findings were presented at a medical conference. They should be considered preliminary as they have not yet undergone the “peer review” process, in which outside experts scrutinize the data prior to publication in a medical journal.

    I have been told that some people have experienced hemorrhaging
    in the brain from taking 81mg aspirin every night. Is there any truth to this

  • Jan,

    One large review concluded, “A reasonable estimate of the risk of hemorrhagic stroke associated with the use of (81 mg) aspirin is 0.2 events per 1000 patient-years.” The review concluded, “The evidence supports that the benefits of aspirin treatment significantly outweigh the risk of a major hemorrhage.”

    But, as I’ve blogged before, there are benefits AND risks of taking a daily aspirin. And every person taking (or considering taking) a daily 81 mg aspirin should talk to their personal physician about the benefits and risks before they make their decision.
