Limited studies of adrenergic function in response to salt-loading suggest that the response of SS patients may differ from that of non-salt sensitive (NSS) patients. The present studies were designed to examine the response of the adrenergic and dopaminergic systems to salt-loading in SS and NSS patients with idiopathic hypertension."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"Accepts Healthy Volunteers", "EligibilityCriteria"=>"Eligibility criteria not identified in protocol."}, "IdentificationModule"=>{"NCTId"=>"NCT00001176", "BriefTitle"=>"Effects of Salt Intake on the Nervous Systems of Patients With Salt-Sensitive High Blood Pressure", "Organization"=>{"OrgClass"=>"NIH", "OrgFullName"=>"National Institutes of Health Clinical Center (CC)"}, "OfficialTitle"=>"The Function of Dopaminergic and Noradrenergic Systems in Salt-Sensitive Hypertension: The Effects of Changes in Sodium Intake", "OrgStudyIdInfo"=>{"OrgStudyId"=>"810081"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"81-H-0081"}]}}, "ContactsLocationsModule"=>{"LocationList"=>{"Location"=>[{"LocationZip"=>"20892", "LocationCity"=>"Bethesda", "LocationState"=>"Maryland", "LocationCountry"=>"United States", "LocationFacility"=>"National Heart, Lung and Blood Institute (NHLBI)"}]}}, "SponsorCollaboratorsModule"=>{"LeadSponsor"=>{"LeadSponsorName"=>"National Heart, Lung, and Blood Institute (NHLBI)", "LeadSponsorClass"=>"NIH"}}}}}}
