Several outlets report that a common but under-recognised genetic condition can increase people’s risk of heart attacks and strokes, describing it as “silent” and largely undetected by routine care.

The articles say the condition is thought to affect a sizeable share of the UK population and that general practitioners rarely test for it. Both pieces frame the issue as a public-health awareness gap, arguing that many people may be unaware they carry the genetic risk factor and therefore may not receive appropriate monitoring or preventive guidance.

While the reporting emphasizes the potential scale of undiagnosed cases and the risk increase, it does not present specific figures or clinical details within the provided excerpts beyond the claim that the condition is associated with a roughly doubled risk of heart attacks. The emphasis is primarily on awareness rather than on new clinical findings, with the shared focus being the need for better identification and testing practices.
