Genetic test could identify an increased risk of heart attack
Test could help to explain why people with no conventional risk factors can still have a heart attack.
Genomic Risk Score (GRS) test would only cost £40.
Test looks for patterns of risky genes rather than a single inherited gene.
Test could be done with a simple mouth swab.
It could be the most cost-effective way for the future for detecting patients with heart attack risks.
Study was published in the Journal of the American College of Cardiology.
