This subproject is one of many research subprojects utilizing theresources provided by a Center grant funded by NIH/NCRR. The subproject andinvestigator (PI) may have received primary funding from another NIH source,and thus could be represented in other CRISP entries. The institution listed isfor the Center, which is not necessarily the institution for the investigator.This study is designed to investigate the changes in blood vessels compliance and stiffness in children ages 5 to 13 years with the syndrome of obstructive breathing during sleep. It is designed to examine the relationship of the severity of the syndrome to vascular functions and to specific inflammatory mediators related to early stages of arterial stiffness and their effect on cardiovascular endpoints, namely twenty-four hour ambulatory blood pressure and left ventricular mass. This study will also examine the relationship between plasma and tonsillar tissue levels of inflammatory cytokines.
Our aim i s to identify vascular risk factors in childhood and to determine whether sleep disordered breathing in children represents an independent risk factor for cardiovascular disease which, if left inadequately identified, could track into adult years.
