'Daily aspirin unlikely to help healthy older people live longer, study finds'

A clinical trial looking at use of daily aspirin in healthy people aged 70 or over, has suggested that there is no overall benefit, when considering risk of death, dementia or physical disability.

The trial involved 19,000 healthy individuals aged 70 years or older, who were asked to take either a low-dose (100mg) aspirin tablet or a placebo (dummy) tablet daily for 5 years. The numbers of people who died or were diagnosed with dementia or a physical disability were similar in the two groups. Aspirin also did not appear to reduce the number of people having a heart attack or stroke as has been seen in studies of other groups of people (such as those with a higher than average risk of these events).
