However, few data are known about the effect of OSAS on cardiovascular system in children.Aims: To investigate clinical and laboratory parameters associated with cardiovascular disease in children with OSAS.Methods: Seventeen subjects, aged 5 to 12 years (mean age 9,24±2,19 years), referring for evaluation of systematic snoring (≥4 nights/week), underwent overnight polysomnography,evaluation of blood pressure, lipidaemic profile and complete echocardiographic assessment. According to the Apnea Hypopnea Index (AHI) subjects were divided into three groups: A. primary snoring (AHI<1, n=1), B. mild OSAS (AHI= 1-5, n=12), C. moderate-severe OSAS (AHI >5, n=4).Results: There were no significantly differences in age, sex, heart rate, systolic and diastolic blood pressure and lipidaemic profile among the groups (p≥0.05).Right ventricular dimension (Right Ventricular end-Diastolic dimension -RVDd) and left ventricular dimensions (Left Ventricular end-Diastolic dimension – LVDd, Left Ventricular diastolic mass – LVdmass, Left Ventricular Posterior Wall diastolic –LVPWd, IntraVenticular Septum diastolic – IVSd)), were not statistically significant different between the three groups and were within normal limits. RVDd was higher in OSAS patients (p=0,096) than in controls.Conclusion: The present study suggests that young patients with systematic snoring have no echocardiographic evidences of cardiac dysfunction. Nevertheless, there is a correlation of increased right ventricular dimension, although not statistically significant, in patients with OSAS.
