People who have previously experienced a heart attack may face a faster decline in cognitive functions, including memory, thinking, and other mental abilities. This is according to a study published in the journal Stroke.

Scientists analyzed data from more than 20,000 adult participants and tracked their cognitive performance over approximately ten years.

The researchers found that individuals with a history of myocardial infarction were more likely to develop cognitive impairment, and their mental abilities declined more rapidly compared to people without such a history. The association was especially noticeable for memory decline and slower thinking speed.

The researchers note that cognitive decline may begin not only after cardiovascular events, but may also reflect a broader process of vascular aging throughout the body.

The study authors emphasize that a heart attack may be a marker of more widespread vascular damage, including damage to blood vessels in the brain. In their view, this could help explain the accelerated cognitive decline observed in these patients.

At the same time, the findings show a statistical association rather than direct proof of a cause-and-effect relationship. The researchers also stress the need for further studies to determine whether preventing cardiovascular disease and controlling risk factors could help slow cognitive aging.
