At least 12 people were urged to seek further medical advice after taking advantage of free blood pressure checks in Swaffham at the weekend.
A team of volunteer nurses administered the tests during a stroke awareness day, which was held at the Assembly Rooms on Saturday.
The event was organised by the Swaffham Rotary Club and aimed to raise awareness of the increased risk of strokes faced by people with high blood pressure.
More than 120 people had their blood pressure checked during the session.
And club member Alan Henry said: “Ten per cent were advised to contact there doctor for further advice by the qualified staff working with us.”
The tests were carried out by nurses from the Swaffham Community Hospital, the town First Responders group and Kay Gulliver.
