title: Metabolic neutrality of perindopril: focus on insulin sensitivity in overweight patients with essential hypertension.
abstract: To assess the effects of antihypertensive treatment with the angiotensin-converting enzyme (ACE) inhibitor perindopril on insulin sensitivity, plasma insulin, and lipoprotein metabolism in overweight hypertensive patients, we measured the insulin sensitivity index (SI, determined according to the minimal model method of Bergman), fasting plasma insulin and glucose concentrations, serum total triglyceride and lipoprotein cholesterol fractions, and blood pressure (BP) in 30 overweight [mean body mass index (BMI) 30.9 kg/m2], nondiabetic patients with essential hypertension after a 4-week run-in period and after 6 weeks of perindopril (n = 20) or placebo (n = 10) administered in a double-blind fashion. Furthermore, we estimated their state of physical fitness using the Conconi bicycle ergometer test before and after perindopril or placebo administration. SI was low in our study population (3.2 vs. 13.3 10(-4) ml.microU-1.min-1 in normal lean control subjects). It did not differ between the perindopril and placebo group after the placebo run-in period (3.1 vs. 3.3 x 10(-4) ml.microU-1.min-1) and was not influenced by perindopril (3.3 x 10(-4) ml.microU-1.min-1) or placebo (3.6 x 10(-4) ml.microU-1.min-1) treatment. Moreover, no significant changes were apparent in fasting plasma insulin and glucose, the areas under the glucose and insulin curves, the glucose disappearance rates, serum total triglycerides (TG), or cholesterol or lipoprotein cholesterol fractions between run-in and active treatment phases in the perindopril or the placebo group, respectively. Heart rate (HR), body weight, and anaerobic threshold remained stable in both groups. Compliance, assessed by pill counting was > 90% in both groups at all visits. Therefore, the ACE inhibitor perindopril is neutral with regard to insulin sensitivity, plasma insulin and glucose, and lipoprotein metabolism in overweight, nondiabetic patients with essential hypertension.
