The document summarizes key elements of the NICE FH Guideline and the work of the HEART UK FH GIT. The NICE guideline recommends using the Simon Broome criteria to diagnose FH and offering all individuals a DNA test to confirm diagnosis and assist with cascade testing of relatives. It also provides guidance on treatment and monitoring for both adults and children with FH. The HEART UK FH GIT works to raise awareness of the NICE guideline, support its implementation through a toolkit, and influence commissioning of FH services to address gaps in care.
