PURPOSE
Essential hypertension is, in some patients, complicated by impairment of insulin-mediated glucose disposal and hyperinsulinemia. Whether this metabolic disturbance is a consequence of the hypertensive process or whether it may precede, and thus possibly promote, the development of hypertension has been unknown.
SUBJECTS AND METHODS
Searching for hereditary or familial defects in hypertension-prone humans, we prospectively investigated insulin sensitivity, plasma insulin and glucose, and serum lipoproteins in normotensive offspring of essential hypertensive as compared with age- and body habitus-matched offspring of normotensive families.
RESULTS
Compared with 78 control subjects, 70 offspring of essential hypertensive parents had similar age (mean +/- SEM: 24 +/- 1 versus 24 +/- 1 years, respectively) and body mass index (22.3 +/- 0.2 versus 22.4 +/- 0.2 kg/m2), a blood pressure of 127/77 +/- 1/1 versus 123/76 +/- 1/1 mm Hg (p less than 0.05 for systolic), and significantly elevated (p less than 0.01 to 0.001) fasting plasma insulin levels (9.9 +/- 0.3 versus 8.6 +/- 0.3 microU/mL), serum total triglycerides (1.03 +/- 0.06 versus 0.83 +/- 0.03 mmol/L), total cholesterol (4.37 +/- 0.08 versus 3.93 +/- 0.07 mmol/L), low-density lipoprotein cholesterol (2.45 +/- 0.08 versus 2.14 +/- 0.07 mmol/L), and total/high-density lipoprotein cholesterol ratio (4.3 +/- 0.1 versus 3.7 +/- 0.1). Insulin sensitivity was lower (9.4 +/- 0.7 versus 13.2 +/- 1.1 x 10(-4) x minute-1/microU/mL, p less than 0.001), while post-glucose-load plasma insulin levels were higher (p less than 0.05) in the 41 offspring of essential hypertensive parents than in the 38 offspring of normotensive parents so investigated.
CONCLUSION
These findings demonstrate that young normotensive humans in apparently excellent health but with one essential hypertensive parent tend to have an impairment of insulin-mediated glucose disposal, hyperinsulinemia, and dyslipidemia. It follows that a familial trait for essential hypertension seems to coexist commonly with defects in carbohydrate and lipoprotein metabolism that can be detected before or at least at a very early stage of the development of high blood pressure as judged by resting blood pressure measurements.
