New genetic test identifies high heart attack risk

A new genetic test is being introduced to identify individuals with a congenital increased risk of suffering a heart attack. According to Olle Melander, a professor at Lund University, approximately one in five people possess this heightened genetic risk, placing them at a similar risk level to individuals with type 2 diabetes or a history of stroke.

The test is designed for use within the healthcare system, specifically for patients in primary care who fall into a 'middle zone'—those who do not present obvious high-risk or low-risk factors such as blood pressure, cholesterol levels, or smoking habits. By identifying genetic susceptibility, doctors can better decide whether to prescribe lifelong medication or recommend lifestyle changes to mitigate risks.

Unlike commercial self-tests, this clinical tool will be administered by physicians to ensure results are managed professionally. The test is expected to be available starting early next year, pending a health economic analysis to determine its cost-effectiveness.
