Abstract:
:Electrocardiographic and cardiovascular responses during maximal exercise were evaluated in 103 normal children and in 82 children with familial hyperlipoproteinemia. The normal and hyperlipidemic children were comparable in regards to age, weight--height index, resting and exercise blood pressures, and maximal working capacity indices. The cohort of 82 hyperlipidemic children included 61 children (29 boys and 32 girls) with well defined "monogenic" familial hyperlipoproteinemia. Segmental ST depression on the exercise electrocardiogram occurred in 8 of these 29 boys (27.6%) as compared to 4 of 55 normal boys (7.3%), P less than 0.025 and in 6 of the 32 girls (19%) as compared to 7 of 48 normal girls (14.6%), P greater than 0.1. Segmental ST depression was present in 14 of 61 (23%) children with "monogenic" hyperlipoproteinemia, as compared to 11 of 103 (10.75%) normal (x2 = 4.47, P less than 0.05). An assessment of the clinical significance of an abnormal exercise electrocardiogram in male children with "monogenic" hyperlipoproteinemia must await the following: (1) two to four decades of observation and study of the development of morbid or mortal coronary disease, or (2) the future development of improved invasive or noninvasive techniques for the early detection of covert coronary occlusive disease. Currently, maximal exercise electrocardiography cannot be contemplated as a useful indicator of eventual premature coronary artery disease in asymptomatic hyperlipidemic children.
