To elucidate potential mechanisms for insulin resistance occurring early in the development of type 2 diabetes, we studied 10 young healthy individuals, each with two first-degree relatives with type 2 diabetes, and 10 control subjects without known type 2 diabetic relatives. They were pairwise matched for age (35 +/- 1 vs. 35 +/- 1 years), BMI (23.6 +/-(More)
Twenty-three men with essential hypertension participated in a double-blind placebo-controlled study with a crossover design to evaluate the long-term (nine weeks) effects of isradipine on central and renal hemodynamics. Isradipine as monotherapy was titrated from 2.5 to 5 and then to 7.5 mg twice daily. At the end of the crossover periods, cardiac output(More)
The reduction of blood viscosity by moderate acute hypervolemic hemodilution in untreated hypertensives can be associated with a secondary vasoconstriction. The aim of this study was to examine whether a vasodilating therapy prevents this hemodynamic reaction. Twelve hypertensive patients (WHO stage II) were treated with the vasoselective calcium channel(More)
In 12 patients with primary hypertension (World Health Organization stage 2) inadequately controlled by chronic standard triple therapy, hydralazine was replaced by felodipine, a new vasodilating dihydropyridine derivative, and the acute effects of the drug on central and renal hemodynamics were monitored. Following baseline measurements, an oral solution(More)
This randomized, double-blind, placebo-controlled crossover study evaluated the effects of the angiotensin II type 1 (AT1)-receptor blocker candesartan cilexetil on renal blood perfusion and glomerular filtration in patients with primary hypertension with diastolic blood pressure of 100 to 114 mm Hg. After a 4-week placebo run-in period, patients were(More)
Sixteen middle-aged men with primary hypertension were treated with the calcium antagonist isradipine over a 9-week period in a randomized, placebo-controlled, double-blind cross-over manner. At the end of the intervention period the urinary albumin excretion rate, systemic and renal haemodynamics, haemorheological properties of blood and plasma(More)
Twenty-three middle-aged men (59 +/- 2 years) with sustained, essential hypertension (WHO Stage II) and with diastolic blood pressure exceeding 100 mmHg during a run-in placebo month were included in a trial designed to assess the clinical and haemodynamic effects of isradipine, a novel dihydropyridine calcium antagonist. The study was double-blind with a(More)
Seventeen middle-aged males with sustained essential hypertension (WHO stage II) and diastolic blood pressures (BP) exceeding 100 mm Hg during a placebo run-in period completed a trial to assess the hemodynamic effects of isradipine, a new dihydropyridine calcium antagonist. The study was double-blind and placebo-controlled with a crossover design. Brachial(More)
Body fat distribution characterized by a high waist/hip ratio (WHR) has been described as a risk factor in the incidence of cardiovascular diseases and associated mortality. Hemorheological changes have been shown to accompany several risk factors. Gynoid and android obese women were compared in the present study with respect to hemorheological and(More)
