New Blood Test Predicts Risk of Heart Attack & Stroke With Twice Previous Accuracy

- New technique, already available in US, could aid in development of cardiovascular drugs. -

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.

“I think this is the new frontier of personalised medicine, to be able to answer the question, does this person need enhanced treatment? And when you’ve treated someone, did it actually work?” said Dr Stephen Williams at SomaLogic in Boulder, Colorado, who led the research. 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 Williams hopes it could be introduced to the UK in the near future. “The NHS is definitely on our radar screen, and we are talking to people about how it might work,” he said. Whereas genetic tests can provide an idea of someone’s risk of certain diseases, protein analysis can provide a more accurate snapshot of what someone’s organs, tissues and cells are doing at any given moment in time.

Williams and his colleagues used machine learning to analyse 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.. 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...

1. That is very exciting news!

3. I'm not entirely sure I'd want to see those results for me.

Heart conditions are rampant in my family, and I myself had a heart attack a bit over a year ago. One artery fully blocked, a stent was put in, and I'm told no other arteries show any kind of blockage, lucky me. I'm 73 years old, and well understand I will not live forever. But as for knowing something more specific about my life expectancy? I think I'll pass.

4. what is the actual name of the test?

Anyone figure that out?

I'm currently participating in the study of the Galleri cancer test that can identify fifty different cancers and note the locus of any that might be found. I get my results tomorrow!

5. The only name I see is a reference to 'SomaLogics' test

to measure blood proteins in the Guardian article. That could be a manufacturer name. Here's the Science publication linked in the article. It doesn't site a specific name either but surely practitioners know about this important new development.

6. funded by Bill and Melinda Gates foundation -- interesting

The next question is --- will Medicare pay for this test?
