[Myocardial geometry and function in overweight and obese adolescents].

114 obese (BMI > 97th age-sex percentile) and 27 overweight (BMI 85-97th age-sex percentile) adolescents (10-18 years) were studied using tissue Doppler echocardiography for the assessment of the geometry of the left ventricle and it's systolic and diastolic functions. Subjects were age and sex matched and grouped according to BMI: + 1-2 SD (Group 1); + 2-3 SD (Group 2) and + > 3 SD (Group 3). It was established that the process of cardiac remodeling in adolescents begins with an initial thickening of the interventricular septum (IVS) at the background of normal values of the myocardial mass index (MMI).
