Do hypercholesterolemia and obesity cause early myocardial deformation changes in children and adolescents?
Hypercholesterolemia and obesity are associated with early subclinical myocardial deformation changes in children and adolescents, with obesity causing an additive adverse effect on ventricular strain.

Dyslipidemia and obesity are considered strong risk factors for premature atherosclerotic cardiovascular disease and increased morbidity and mortality and may have a negative impact on myocardial function.Our purpose was to assess the presence of early myocardial deformation abnormalities in dyslipidemic children free from other cardiovascular risk factors, using 2-dimensional speckle tracking echocardiography (2DSTE) and 3-dimensional speckle tracking echocardiography (3DSTE).We studied 80 consecutive nonselected patients (6-18 years of age) with hypercholesterolemia (low-density lipoprotein LDL cholesterol levels >95th percentile for age and sex). Forty of them had normal weight and 40 were obese (body mass index >95th percentile for age and sex). Forty healthy age-matched children were selected as controls. Left ventricular (LV) global longitudinal, circumferential, and radial strains were calculated by 2DSTE and 3DSTE. Global area strain (GAS) was calculated by 3DSTE as percentage of variation in surface area defined by the longitudinal and circumferential strain vectors. Right ventricular (RV) global and free-wall longitudinal strain and LV and RV diastolic strain rate parameters were obtained. Data analysis was performed offline.LV global longitudinal strain and GAS were lower in normal-weight and obese dyslipidemic children compared with normal controls and reduced in obese patients compared with normal-weight dyslipidemic children. LV early diastolic strain rate was lower compared with normals. RV global and free-wall longitudinal strain was significantly reduced in obese patients when compared with the control group. A significant inverse correlation was found between LV strain, LDL cholesterol levels, and body mass index.2DSTE and 3DSTE show LV longitudinal strain and GAS changes in dyslipidemic children and adolescents free from other cardiovascular risk factors or structural cardiac abnormalities. Obesity causes an additive adverse effect on LV strain parameters and RV strain impairment.
Vitarelli et al. (Mon,) conducted a observational in Hypercholesterolemia and Obesity (n=120). Hypercholesterolemia (normal weight) vs. Healthy controls was evaluated on 3D-derived Global Area Strain (GAS) (p=0.002). Hypercholesterolemic children and adolescents exhibited significantly reduced left ventricular global area strain compared to healthy controls, with obesity causing an additive adverse effect.
