In the study, older adults in Australia who did not have heart disease, diabetes, or dementia took either atorvastatin 40 mg each day or a placebo, which is a pill with no medicine. Researchers looked at two main questions: whether the drug lowered major heart problems, such as death from heart disease, heart attack, stroke, or heart procedures to open blocked arteries, and whether it helped people live longer without dementia or physical disability.
Guidelines have not had strong evidence about starting statins in adults aged 70 and older without heart disease because most older studies included younger people. This study found that atorvastatin lowered the risk of major heart problems, but it did not clearly help people live longer without disability or dementia. It suggests that statins may help some older adults, but they should not be given to everyone automatically. Doctors should decide based on each patient’s health, risk, and preferences. One limitation is that no African American patients were included in the study.
