    Abstract:
    UNLABELLED: AimThe present study aimed to evaluate systolic and diastolic myocardial function in children and adolescents with congenital adrenal hyperplasia. METHODS: The study included 44 children with the diagnosis of classic congenital adrenal hyperplasia and 39 healthy children whose age, pubertal status, and gender were similar to those of the patient group. Anthropometric parameters and 17-hydroxyprogesterone levels were measured, and bone age was calculated. The average daily hydrocortisone dose was calculated over the last 1-year file records. Hyperandrogenic state was defined according to bone age SD score (⩾2) and 17-hydroxyprogesterone levels (>10 ng/ml). Echocardiographic examinations were assessed by conventional two-dimensional Doppler echocardiography and tissue Doppler imaging. RESULTS: Patients had higher morphological parameters, such as left ventricular end-systolic diameter, interventricular septal thickness at end diastole, left ventricular posterior wall thickness at end diastole, left ventricular mass and index, than the control group (p<0.05). On pulsed-wave and tissue Doppler echocardiography, significant subclinical alterations were observed in systolic (isovolumic contraction time), diastolic (isovolumic relaxation time), and global left ventricular functional (myocardial performance index) parameters in the congenital adrenal hyperplasia group compared to the control group (p<0.05). In partial correlation analyses, after controlling the effect of hyperandrogenism, the mean hydrocortisone dosage was positively correlated with isovolumic relaxation time in congenital adrenal hyperplasia group (p<0.05). CONCLUSION: This study demonstrated that the patients with congenital adrenal hyperplasia are at risk for left ventricular hypertrophy, systolic and diastolic myocardial subclinical alterations. Overtreatment may be responsible for the increased risk of myocardial dysfunction in patients with congenital adrenal hyperplasia.
