Key result
A healthy lifestyle was significantly associated with a reduced risk of major adverse cardiac events (HR 0.69 per 1-point increase in lifestyle score) in patients with familial hypercholesterolemia.
Why the study?
Pathogenic mutations associate with poor outcomes in familial hypercholesterolemia, but data on the effects of a healthy lifestyle on FH phenotypes are limited.

Does a healthy lifestyle reduce major adverse cardiac events in patients with familial hypercholesterolemia?
Hazard Ratio: 0.69 (95% CI 0.4–0.98)
p-value: p=0.033
Adherence to a healthy lifestyle significantly mitigates the inherited cardiovascular risk in patients with familial hypercholesterolemia, regardless of their genetic mutation status.
May support lifestyle counseling in FH; leaves open genotype-specific effects in prospective studies.
Background: Pathogenic mutations are associated with poor outcomes in patients with familial hypercholesterolemia (FH). However, data on the effects of a healthy lifestyle on FH phenotypes are limited. Objectives: The authors investigated the interaction between a healthy lifestyle and FH mutation with prognosis in patients with FH. Methods: We investigated the associations of the interaction between genotypes and lifestyle, with the occurrence of major adverse cardiac events (MACE), such as cardiovascular-related mortality, myocardial infarction, unstable angina, and coronary artery revascularization, in patients with FH. We assessed their lifestyle based on 4 questionnaires (healthy dietary pattern, regular exercise, not smoking, and absence of obesity). The Cox proportional hazards model was used to assess the risk for MACE. Results: 0.033, respectively). The estimated risk of coronary artery disease by 75 years of age varied according to lifestyle, ranging from 21.0% among noncarriers with a favorable lifestyle to 32.1% among noncarriers with an unfavorable lifestyle and ranging from 29.0% among carriers with a favorable lifestyle to 55.4% among carriers with an unfavorable lifestyle. Conclusions: A healthy lifestyle was associated with reduced risk for MACE among patients with FH with or without genetic diagnosis.

Tada et al. (2023) conducted a cohort in Familial Hypercholesterolemia (n=961). Healthy lifestyle score (healthy dietary pattern, regular exercise, not smoking, absence of obesity) vs. Unfavorable or intermediate lifestyle was evaluated on Major adverse cardiac events (MACE), including cardiovascular-related mortality, myocardial infarction, unstable angina, and coronary artery revascularization (HR 0.69, 95% CI 0.40-0.98, p=0.033). A healthy lifestyle was significantly associated with a reduced risk of major adverse cardiac events (HR 0.69 per 1-point increase in lifestyle score) in patients with familial hypercholesterolemia.
