New CVD guidelines mark ‘big shift’ for risk thresholds, says leading GP

New CVD risk categories need more explanation, says Emeritus Professor Mark Harris.

Changes to CVD guidelines will benefit patients just below the high-risk threshold, but questions remain over the new percentage-based risk categories, says a leading GP.

The RACGP-endorsed Australian CVD Risk Calculator — released by the National Heart Foundation of Australia last week — includes a recalibrated version of the PREDICT-1° algorithm, based on data from a New Zealand primary cohort study and adjusted for the Australian population. 

Emeritus Professor Mark Harris, who was not involved in the guidelines’ development, said it was a “big shift” from the previous calculator and decades-old Framingham equation.  

He said GPs would benefit from the ability to adjust risk estimates according to new reclassification factors: severe mental illness, ethnicity, family history and coronary artery calcium (CAC) scoring.
