Abstract
This article reviews the current landscape of cardiovascular disease (CVD) risk factors, focusing on dyslipidemia, which contribute to atherosclerosis in three unique populations: youth less than 18years-of-age with a history of Kawasaki disease, and those who have undergone orthotopic heart and bone marrow transplants. Atherosclerosis, the major cause of CVD, begins in childhood. Acquired and genetic disorders of lipid and lipoprotein metabolism, present at an early age, are major contributors to early precursors of atherosclerosis, which accelerate after age 20. Treatment of the underlying medical condition and optimum management of all risk factors is critical in improving outcomes. Nonetheless, limited data is available to assist clinical decision-making, with the aim of improving outcomes. Atherosclerosis, beginning in childhood, is multifactorial in origin with complex interplay of inflammation, infection, endothelial dysfunction, and dyslipidemia. Future studies are needed to help elucidate the specific roles of disease mechanisms, with an emphasis on early intervention and prediction of subclinical disease. In addition to a heart healthy lifestyle, there may be a role for use of lipid-lowering medications beginning at an early age.
