Abstract

The purpose of this study was to determine the interdependent and independent effects of hypertension and obesity on endothelial function in humans. We evaluated the forearm blood flow (FBF) response to acetylcholine, an endothelium-dependent vasodilator, and isosorbide dinitrate (ISDN), an endothelium-independent vasodilator, in 16 lean and 12 obese normotensive individuals and the 18 lean and 15 obese hypertensive patients with no history of smoking, hypercholesterolemia, diabetes mellitus, or renal dysfunction. The FBF was measured using a mercury-filled Silastic strain-gauge plethysmograph. The systolic and diastolic blood pressures (BP) and forearm vascular resistance were significantly greater in hypertensive patients than in the normotensive individuals. Insulin resistance, determined by a homeostatic model assessment (HOMA), was significantly greater in the obese group than in the lean group (3.59 +/- 1.68 v 1.91 +/- 1.12, P < .01). There was no significant difference in the HOMA index between normotensive and hypertensive subjects regardless of weight. The response of FBF to acetylcholine was greatest in lean normotensive individuals and least in obese hypertensive patients (40.5 +/- 8.5 and 10.4 +/- 2.8 mL/min/100 mL of tissue, P < .001 v other groups). The FBF response was similar in obese normotensive individuals and lean hypertensive patients (24.1 +/- 7.9 and 19.3 +/- 3.2 mL/min/100 mL of tissue). The vasodilatory effect of ISDN was similar in all four groups. Multiple regression analysis revealed that the maximal FBF response to acetylcholine correlated independently with age (P = .043), obesity (P = .012), HOMA index (P = .002), and mean BP (P < .001). These findings suggest that obesity and hypertension are independently involved in abnormal endothelium-dependent vasodilation by attenuated nitric oxide production.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
