Hui W, et al. - In this prospective, single-center, observational, cross-sectional study involving 44 obese patients as well as 44 age- and sex-matched control participants, researchers assessed the impact of obstructive sleep apnea (OSA) on cardiovascular functional parameters in obese youth. Polysomnography and cardiovascular assessment, including functional echocardiography and carotid-femoral pulse wave velocity (PWV), were performed on all patients. Findings revealed an impact of both obesity and OSA on cardiovascular performance in obese youth. Results showed an association of obesity with increased left ventricular (LV) mass and reduced LV diastolic function; changes in arterial stiffness were also observed in relation to OSA.
