New Blood Test Predicts Risk of Heart Attack, Stroke With Twice Previous Accuracy
An anonymous reader quotes a report from the Guardian: Scientists have developed a blood test that can predict whether someone is at high risk of a heart attack, stroke, heart failure or dying from one of these conditions within the next four years. The test, which relies of measurements of proteins in the blood, has roughly twice the accuracy of existing risk scores. It could enable doctors to determine whether patients' existing medications are working or whether they need additional drugs to reduce their risk. It could also be used to hasten the development of new cardiovascular drugs by providing a faster means of assessing whether drug candidates are working during clinical trials. The test is already being used in four healthcare systems within the US and [...] it could be introduced to the UK in the near future. [Researchers] used machine learning to analyze 5,000 proteins in blood plasma samples from 22,849 people and identify a signature of 27 proteins that could predict the four-year likelihood of heart attack, stroke, heart failure or death. When validated in 11,609 individuals, they found their model was roughly twice as good as existing risk scores, which use a person's age, sex, race, medical history, cholesterol and blood pressure to assess their likelihood of having a cardiovascular event. The results were published in Science Translational Medicine. Importantly, the test can also accurately assess risk in people who have previously had a heart attack or stroke, or have additional illnesses, and are taking drugs to reduce their risk, which is where existing risk prediction scores tend to fall down.Read more of this story at Slashdot.
