Elevated Lp(a) in children with parental CVD or pCVD reflects a strong heritable pattern from early life. FH was associated with modest but consistent Lp(a) elevation, indicating an independent risk-modifying role rather than a defining feature. Sex-related differences were minimal, whereas ethnic variation was prominent. These findings support targeted Lp(a) assessment in children with familial cardiovascular risk using ancestry-aware reference standards, with consideration of repeat evaluation in early adulthood in higher-risk individuals.
