Does lifestyle contribute to disease severity in patients with inherited lipid disorders?

PURPOSE OF REVIEW

Patients with familial hypercholesterolemia, familial combined hyperlipidemia and hyperlipoprotein(a) are at high cardiovascular risk. Increasing evidence suggest that lifestyle-related risk factors such as physical inactivity, and poor diet quality could influence cardiovascular risk in these patients. Our objective is to review the evidence that supports the role of lifestyle-related factors in the prediction of cardiovascular risk in patients with inherited lipid disorders.

RECENT FINDINGS

Recent studies have shown that smoking, a poor diet quality, physical inactivity, fitness levels, abdominal obesity, insulin resistance, and type 2 diabetes were associated with the presence of atherosclerosis and long-term cardiovascular outcomes in patients with familial hypercholesterolemia. Recent evidence also suggest that managing other cardiovascular risk factors such as cholesterol levels, obesity, glycemic control, blood pressure, smoking, physical inactivity, and diet quality could reduce long-term cardiovascular risk associated with hyperlipoprotein(a). Whether targeting these risk factors could ultimately decrease cardiovascular risk in these patients remains unknown.

SUMMARY

Although reducing the number of atherogenic apolipoprotein-B containing particle with lipid-lowering therapy represents the cornerstone of treatment of patients with inherited lipid disorders, lifestyle-related risk factors such as physical inactivity and poor diet quality need to be targeted for the optimal management of these high-risk patients.
