Blood Test Detects Heart Disease Before Symptoms
Doctors may soon be able to use a new blood test to diagnose cardiovascular disease earlier—before symptoms develop. According to a 9-year study involving 90 people with no known heart disease, the new test, which measures the immune response to inflammation in the body, was more accurate than other methods, such as the C-reactive protein (CRP) test and cholesterol testing.
Study participants—60 over the age of 60 and 30 under the age of 40—were given flu vaccines every year and researchers used various tests to evaluate their response to the vaccine, test their immune function, and measure inflammation markers in their blood. They found a connection between vaccine response and chronic inflammation—which is an indicator for heart disease.
By looking at certain markers and proteins in the blood, researchers were able to accurately measure inflammation in the body and immune system response. Over the course of the study, the results correlated with each participant’s clinical signs of heart disease.
