The new blood test improves the diagnosis of heart disease

25 new biomarkers discovered for heart failure

The new blood test for heart disease currently causes anxiety in medical research. The new method will include 25 additional biomarkers for heart failure, making the diagnosis more accurate and reliable. For comparison, in today's study, only one protein is used for diagnosis.

Researchers at the Queen's University in Belfast have recently presented a new test in order to revolutionize the diagnosis of heart disease. Especially in the discovery of heart failure (heart failure), the new blood test should bring significant improvements. The team identified 25 new proteins that indicate the presence of heart failure. The results of the study were recently presented at a conference of the British Cardiovascular Society.

Cardiac failure is the most common cause of hospitalization

Heart failure is a long-term condition that occurs when the heart is unable to pump blood throughout the body as effectively as it should. The main symptoms of heart failure are shortness of breath, chronic fatigue, and often a feeling of weakness. However, in many people, only clear symptoms show when the disease is already advanced. In Germany, two to three million people are affected by heart failure. Cardiac disease is the most common cause of hospitalization.

The current diagnosis is obsolete

At present, for the diagnosis of heart failure, a protein level called B-type natriuretic peptide (BNP) is used routinely. Increased levels of this protein are considered as a signal of risk for the presence of heart failure. However, there are many reasons for the increased level of BNP, researchers say. For example, some drugs, high body weight and age can lead to changes in the level of the mirror. These factors can affect the accuracy and reliability of BNP measurements.

For the first time, several biomarkers have been used for heart failure

The team around the doctor. Chris Watson et al. Claire Tony now identifies 25 other biomarkers associated with heart failure. These should now be established in the blood to support the diagnosis. "There is an urgent need to develop tests that can diagnose heart failure earlier and more precisely to improve outcomes for patients with this disease," said Dr. Tony in a press release on the results of the study. "With our new method, we can measure several proteins simultaneously from a small amount of blood for the first time," says the expert.

Initial treatment of heart failure is important

"We see a significant increase in people going to hospital with heart failure," added Dr. Sonya Babu-Narayan of the British Heart Foundation. The population is getting older, and more and more people develop heart failure after surviving a heart attack. It is crucial to diagnose heart failure as soon as possible, since early treatment can effectively delay the progression of the disease. "This will help the affected people get a better grip of their symptoms so they can live a more complete and more active life longer," the doctor sums up. (Vb)
