- Familial hypercholesterolemia (FH) affects roughly one in 250 people and is heavily underdiagnosed.
- Untreated FH carries an approximately 20-fold increased lifetime risk of premature coronary heart disease.
- Statin therapy started in young adulthood normalizes lifetime cardiovascular risk close to the population baseline.
- Family cascade testing typically finds additional affected relatives in the same generation and the prior generation.
