OBJECTIVE: Impaired basal nitric oxide release is associated with a number of cardiovascular disorders including hypertension, arterial spasm, and myocardial infarction. We determined whether basal endothelial nitric oxide release is reduced in otherwise healthy overweight and obese adult humans.
RESEARCH METHODS AND PROCEDURES: Seventy sedentary adults were studied: 32 normal weight (BMI/m(2)), 24 overweight (BMI > or = 25 < 30 kg/m(2)), and 14 obese (BMI > or = 30 kg/m(2)). Forearm blood flow (FBF) responses to intra-arterial infusions of N(g)-monomethyl-L-arginine (5 mg/min), a nitric oxide synthase inhibitor, were used as an index of basal nitric oxide release.
RESULTS: N(g)-monomethyl-L-arginine elicited significant reductions in FBF in the normal weight …
