Blood Test Helps Predict Future Heart Attacks

In a recent study, researchers have found that a standard blood test can indicate whether an individual is at a high risk of experiencing a heart attack within the next six months. The study, published in Nature Cardiovascular Research on Feb. 12, identified numerous biomarkers in the blood that are linked to the risk of a first heart attack.

Johan Sundstrom, the lead researcher and a cardiologist at Uppsala University in Sweden, stated that existing healthcare blood samples are sufficient for predicting the impending risk of a heart attack. Predicting heart attacks has been challenging because most known risk factors manifest long before the emergency occurs.

Analyzing blood samples taken at least six months before the first heart attack from 420 individuals, researchers compared the results to those of nearly 1,600 healthy individuals. They identified around 90 molecules, including 48 proteins and 43 biochemicals related to the risk of a first heart attack. Combining this information with age, sex, and blood pressure, researchers developed an online tool at miscore.org, enabling individuals to assess their risk of a heart attack within the next six months based on various factors.

Sundstrom emphasized the potential for increased motivation to adopt preventive measures if individuals learn about their elevated risk, such as taking prescribed medication or quitting smoking. The researchers plan to further study the 90 biomarkers to explore treatment opportunities for preventing imminent heart attacks.
