RESUMO

<p><b>Background</b>Postmenopausal women with metabolic syndrome (MetS) have increased cardiovascular morbidity and left ventricular diastolic dysfunction (LVDD). The various protective effects of astragalus membranaceus (AM) have been described in previous studies. Therefore, this study aimed to evaluate the effects of different doses of AM on diastolic function in postmenopausal hypertensive women with MetS.</p><p><b>Methods</b>This was a prospective, randomized controlled study. The postmenopausal hypertensive patients with MetS were enrolled from Lanzhou University Second Hospital from March 2014 to April 2015. Patients were divided into three groups: control group (received conventional medical treatment), AM Group 1 (received AM capsules at 5 g/d additionally), and AM Group 2 (received AM capsules at 10 g/d additionally). Echocardiographic and clinical characteristics were evaluated before and 12 months after treatment. Quantitative data were analyzed using unpaired t-test, analysis of variance, and multiple linear regression analysis.</p><p><b>Results</b>A total of 154 patients were subjected to final analysis. In the AM Group 2, significant improvements were noted in diastolic function 12 months after treatment than those of the control group, including the early diastolic mitral annular velocity (E'; 0.065 ± 0.007 m/s vs. 0.061 ± 0.008 m/s, P = 0.014), the ratio of the early diastolic mitral peak flow velocity to the late diastolic mitral peak flow velocity (E/A; 0.81 ± 0.05 vs. 0.80 ± 0.06, P = 0.012), the ratio of E' to the late diastolic mitral annular velocity (E'/A'; 0.56 ± 0.12 vs. 0.51 ± 0.13, P = 0.048), and the ratio of the early diastolic mitral peak flow velocity (E) to E' (E/E'; 10.70 ± 1.30 vs. 11.37 ± 1.73, P = 0.031). After treatment, E/E' (10.70 ± 1.30 vs. 11.24 ± 1.56, P = 0.021), deceleration time (DT; 261.49 ± 44.41 ms vs. 268.74 ± 53.87 ms, P = 0.046), and E'/A' (0.56 ± 0.12 vs. 0.52 ± 0.13, P = 0.019) values improved more significantly than those of AM Group 2 before treatment.

RESUMO

<p><b>OBJECTIVE</b>To compare the effects of felodipine combined irbesartan regimen with that of felodipine combined metoprolol regimen on the sexual function in male hypertensive patients.</p><p><b>METHOD</b>One hundred and twenty-three male hypertensive patients (age 25 to 60) were randomly assigned to felodipine (5 mg/d) plus irbesartan (150 mg/d, n = 64) group and felodipine (5 mg/d) plus metoprolol (47.5 mg/d, n = 59) group. Dosage of felodipine were doubled after 4 weeks if the blood pressure were > or = 140/ 90 mm Hg (1 mm Hg = 0.133 kPa). At the baseline and post 24th week treatment, sexual function of patients was assessed by the International Index of Erectile Function (IIEF) Questionaire. Serum testosterone (T), sex hormone binding globulin (SHBG), 4-hydroxynonenal (HNE), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and Malonaldehyde (MDA) were measured by Radioimmunoassay (RIA), ELISA and TBA respectively.</p><p><b>RESULTS</b>Total prevalence of erectile dysfunction (ED), T, SHBG and HNE were similar between pre- and post-treatment in two groups (P > 0.05). On the other hand, the scores of the mild ED and sexual desire (SD) were improved and both serum 8-OHdG and MDA in patients with ED decreased [(146.02 +/- 60.54) ng/L vs. (139.89 +/- 62.03) ng/L, P = 0.048 and (6.59 +/- 1.75) micromol/L vs. (5.51 +/- 1.65) micromol/L, P = 0.039] in Felodipine plus Irbesartan group.</p><p><b>CONCLUSION</b>The results suggested that Felodipine + Irbesartan regimen may be superior to Felodipine + metoprolol regimen for male hypertensive patients with mild ED.</p>
