Blood pressure control in the Hypertension in the Very Elderly Trial (HYVET).

To report blood pressure control in the Hypertension in the Very Elderly Trial, a placebo-controlled trial of hypertensive (systolic blood pressure (SBP) 160-199 mm Hg, diastolic blood pressure (DBP) <110 mm Hg) participants over the age of 80 years, given treatment in three steps: indapamide slow release 1.5 mg alone, indapamide plus 2 mg perindopril and indapamide plus 4 mg perindopril. The difference in control between participants with combined systolic and diastolic hypertension (SDH, DBP90 mm Hg) and those with isolated systolic hypertension (ISH, DBP<90 mm Hg) is determined together with the effects of increments in the treatment regimen. At 2 years, the active treatment lowered blood pressure by 16.5/6.9 mm Hg more than that on placebo in participants with SDH and by 19.3/4.8 mm Hg more in those with ISH. The 2-year falls in pressure on placebo alone were 13.2/8.5 mm Hg in SDH and 8.2/1.5 mm Hg in ISH participants. With full titration of active treatment, 62% of SDH participants achieved goal SBP (<150 mm Hg) by 2 years and 71% of those with ISH. The corresponding results for DBP control (<80 mm Hg) were 40 and 78%. The addition of active perindopril 2 mg roughly doubled the percentage controlled, as did increasing to 4 from 2 mg. Blood pressure control was good with ISH and better than with SDH. The fall in SBP accounted for the observed 30% reduction in strokes, but the 21% reduction in total mortality and 64% reduction in heart failure were greater than predicted.

Reduced concentrations of soluble adhesion molecules after antioxidant supplementation in postmenopausal women with high cardiovascular risk profiles--a randomized double-blind study.

BACKGROUND: One of the suggested mechanisms of increased cardiovascular risk in postmenopause is a loss of the antioxidant effects of estrogens. It has been shown that classical cardiovascular risk factors increase oxidative stress on the arterial wall, and that endothelial cells react to this insult by increased expression of cellular adhesion molecules (CAM), which in turn are markers of arterial wall inflammation. METHODS: A randomized, placebo-controlled, double-blind study was performed in 60 postmenopausal women with high cardiovascular risk profiles, but free from clinical atherosclerotic disease. Patients were randomized to either antioxidant supplementation (using a combination of natural antioxidants; n = 30) or placebo (n = 30), and followed for 12 weeks. The concentrations of the adhesion molecules sVCAM-1 and sICAM-1 were measured by ELISA at baseline and at the end of the study, as well as total cholesterol, LDL, HDL, triglycerides and blood pressure. RESULTS: 27 women in the antioxidant supplementation group and 29 on placebo completed the study. At baseline, there were no significant differences in measured parameters between the groups: sICAM-1 concentrations were 341.8 +/- 116.9 vs. 349.9 +/- 104.6 ng/ml (active treatment vs. placebo; p = n.s.) and sVCAM-1 concentrations were 780.5 +/- 325.8 vs. 761.0 +/- 333.7 ng/ml (p = n.s.). In contrast, at the end of the study, sICAM-1 concentrations were 301.6 +/- 56.0 vs. 356.0 +/- 134.8 ng/ml (active treatment vs. placebo; p = 0.053) and sVCAM-1 concentrations were 656.0 +/- 326.5 vs. 818.5 +/- 381.0 ng/ml (p = 0.04). There were no significant differences between or changes within the groups in measured cholesterol and blood pressure. CONCLUSION: Antioxidant supplementation reduces serum concentrations of endothelium-derived adhesion molecules sICAM-1 and sVCAM-1 in postmenopausal women with high cardiovascular risk profiles.

[Clinical studies of celiprolol in the treatment of arterial hypertension]. / Klinichni prouchvaniia na tseliprolol pri lechenie naarterialna khipertoniia.

The antihypertensive effect of the preparation celiprolol was studied in a double blind experiment versus acebutolol in 60 patients (30 males and 30 females), with an average age 40 years. Only patients with hypertonic diseases, stage I-II, according to WHO classification were included in the study. The treatment Lasted 4 weeks. The criteria for a good effect were the normalization of the blood pressure and the absence of adverse effects. There was no statistically significant difference between the percentages of the reduced blood pressure, attained by both preparations. By the end of 4th week, 56.7 per cent of the treated with celiprolol were with normalized blood pressure, and 46,7 per cent--with acebutolol. The following adverse effects were observed: light gastrointestinal manifestations, weakness, dizziness, tremor, impotence. In some of the patients those effects were transitory but in 4 patients, treated with acebutolol, the treatment was discontinued because of the adverse effects.
