Cardiovascular disease prevention in heterozygous familial hypercholesterolemia: how important is a healthy diet in the era of long-lasting cholesterol-lowering drug therapies?

Purpose of review: This review aims to provide an in-depth perspective on the importance of diet for cardiovascular disease (CVD) prevention in heterozygous familial hypercholesterolemia (HeFH).

Recent findings: Even though data on diet and CVD prevention in HeFH are limited, the currently available evidence supports its cholesterol-lowering effect and its favorable association with CVD risk on the long-term. However, qualitative evidence from individuals with HeFH suggests that there is a common perception that diet is useless compared to medication, and this misconception serves as a barrier to healthy eating. On the other hand, evidence also suggests that individuals with HeFH are at higher risk of eating disorders compared with unaffected individuals. Family history of premature death and the chronic nature of the disease would be in cause.

Summary: Emphasizing a healthy diet needs to remain at the foundation of CVD prevention in HeFH. Evidence are limited but supportive of the cholesterol-lowering and cardioprotective potential effects of diet. Engaging in conversations about healthy dieting with individuals in HeFH is likely to help prevent misconceptions about diet. Additionally, it could help reduce the risk of eating disorders, which, altogether, is likely to improve overall CVD prevention.
