New risk tool to predict atrial fibrillation risk

A new risk score could help identify people at most risk of atrial fibrillation in primary care, claims a new US study.

Using data from the Framingham Heart Study, the researchers selected 4,800 individuals aged 45 to 95 years without signs of atrial fibrillation and followed them for a decade.

They identified various clinical factors that were associated with the occurrence of atrial fibrillation – including age, sex, PR interval, blood pressure and a clinically significant heart murmur – to develop the new risk score.
