Abstract
Patients with hypertension tend to be glucose intolerant, hyperinsulinemic, and dyslipedemic. Since all of these changes increase risk of coronary heart disease (CHD), it is important to know what effect antihypertensive treatment has on these variables. The current open-labelled, uncontrolled study was initiated in order to extend our understanding of these issues. This study was performed in 19 patients with hypertension who were started on an angiotensin converting enzyme (ACE)-inhibitor, cilazapril, with hydrochlorothiazide (HC) added if needed to control blood pressure. Plasma glucose and insulin responses to oral glucose and lipid concentrations were measured before, 26, and 52 weeks after starting treatment. Patients treated with either cilazapril (n = 9) or cilazapril+HC (n = 10) did not differ in terms of original (mean +/- SEM) blood pressure (159 +/- 5/101 +/- 1 v 156 +/- 4/103 +/- 2 mm Hg), age (53 +/- 2 v 54 +/- 2 years), sex distribution (5M:4F v 7M:3F), or body mass index (24.4 +/- 0.5 v 24.2 +/- 0.9 kg/m2). Blood pressure was also similar after 26 (137 +/- 4/88 +/- 1 v 133 +/- 3/90 +/- 1 mm Hg) and 52 (137 +/- 4/87 +/- 1 v 134 +/- 4/89 +/- 2 mm Hg) weeks of treatment. Plasma glucose and insulin responses decreased by 8 +/- 3% (P less than .05) and 25 +/- 9% (P less than .002), respectively, in cilazapril-treated patients, but did not change in those treated with cilazapril plus HC.(ABSTRACT TRUNCATED AT 250 WORDS)
