The prediction of risk can make a significant contribution to preventing heart attacks. Researchers have now discovered that a simple blood test, combined with an online tool, can predict a person’s risk for a heart attack within the next six months.

The researchers at Uppsala University in Sweden developed the concept based on the hypothesis that several biological processes occur in the months before a heart attack, which can be identified through a blood test.

„The time leading up to a heart attack is very dynamic. For example, the risk of a heart attack doubles in the month after a divorce, and the risk of a fatal heart event is five times higher in the week after a cancer diagnosis,“ said Johan Sundström, a cardiologist and professor of epidemiology at Uppsala University, who led the research.

The researchers had blood samples from six European groups, consisting of 169,053 individuals with no history of heart disease. Within six months, 420 of them experienced their first heart attack. The researchers then examined their blood samples and compared them to those of 1,598 healthy individuals from the same groups. The results were published in the journal Nature.

„We wanted to develop methods that would allow healthcare services to identify people who will soon experience their first heart attack. We identified around 90 molecules that were associated with the risk of a first heart attack. The results in healthcare are now sufficient to predict the risk. We hope that this will increase people’s motivation to take preventive medications, for example, or to quit smoking,“ Sundström said.

The research team also developed an online tool that allows anyone to determine their risk for a heart attack within six months. The team stated that patients can be motivated to change their lifestyle and prevent heart attacks by knowing the risks.

„This was one of the goals of the entire study, as we know that people’s motivation to seek preventive treatment is relatively low. If you find out that you randomly have an increased risk of experiencing a heart attack soon, you might feel more motivated to prevent it,“ Sundström said.

The researchers will now further investigate the identified molecules to better understand them and explore the possibility of treatment. „We hope to conduct a new study here in Uppsala to find out if the online tool provides the kind of motivation we intend,“ Sundström concluded.
