title: Insulin resistance, hyperinsulinemia, and dyslipidemia in nonobese individuals with a family history of hypertension.
abstract: Various facets of glucose, insulin, and lipid metabolism were compared in 76 normal volunteers--38 with and 38 without a family history of hypertension. The two groups were comparable in terms of age, gender distribution, and degree of obesity (both generalized and abdominal). Although the plasma glucose response to oral glucose was similar in both groups, glucose-stimulated insulin concentrations were significantly greater in volunteers with a family history of hypertension (P < .001). Furthermore, the steady state plasma glucose concentration during a constant infusion of glucose, insulin and somatostatin was significantly greater in subjects with a family history of hypertension (8.1 +/- 0.6 v 6.2 +/- 0.6 mmol/L, P < .001). Since the steady-state plasma insulin levels during the infusion were similar, these results indicate that normotensive individuals with a family history of hypertension are relatively insulin resistant. Finally, plasma very low density lipoprotein (VLDL) triglyceride and VLDL cholesterol were higher in those with a family history of hypertension, as was the ratio of total to high density lipoprotein cholesterol. Thus, normotensive individuals with a family history of high blood pressure are insulin resistant, hyperinsulinemic and dyslipidemic when compared to a matched group of healthy volunteers without a family history of hypertension.
