FH Awareness Day is on September 24th
Family Heart Foundation, September 2022

Millions of people around the world do not know that they and their families are at severe risk for early heart disease, heart attacks, and even death. Seven out of ten people born today with familial hypercholesterolemia are undiagnosed. Yet, with early diagnosis and treatment, individuals diagnosed with FH can reduce their risk for heart disease by 70%. Together we can raise awareness, find every individual with FH, and prevent early heart disease.

JW Gronedick et al, JAMA Internal Medicine, August 22, 2022

In this review, polygenic risk scores were significantly associated with CHD risk in all studies. The degree of improvement in C statistic and the net reclassification indexes when PRS was added to traditional risk scores ranged from negligible to modest. Based on established metrics to assess risk prediction scores, the addition of PRS to traditional risk scores does not appear to provide meaningful improvements in clinical decision-making in primary prevention populations.
