Taking aspirin at bedtime instead of in the morning might reduce acute heart events, according a new study presented at the American Heart Association’s Scientific Sessions 2013.
Low-dose daily aspirin is recommended for people at high risk of heart disease and for reducing the risk of recurrent heart events. Aspirin thins the blood and makes it less likely to clot. Blood platelets are a key component of clotting, and the tendency for platelet activity to be higher peaks in the morning.
In a trial that explored the timing of aspirin intake among cardiovascular disease patients, researchers found that platelet activity was lower in people who took aspirin at bedtime compared to those who took it in the morning.
Because higher platelet activity contributes to a higher risk of acute heart events scientists say switching aspirin intake from morning to bedtime could be helpful for people with heart disease who take daily aspirin.
