简要总结
Aim: To evaluate the effects of Valsartan versus Amlodipine on LV deformation in relation to plasma adiponectin and leptin levels in hypertensive individuals.
Methods: LV strain measured by 2 dimensional speckle tracking echocardiography, plasma levels of adiponectin and leptin was determined in 30 healthy individuals served as control group and in 200 hypertensive patients before and after treatment for three months with either Valsartan 160 mg or amlodipine 10 mg.
详细描述
Patients and methods Thirty control healthy individuals and 200 patients with uncomplicated, essential hypertension were enrolled and followed up for 3 months in a controlled randomized study. All subjects' health status was evaluated by a complete medical examination. All BP measurements were made with calibrated mercury manometers (Korotkoff I and V). Three separate measurements were taken at least 2 min apart and the average of these values was calculated. Subjects' height and weight were recorded in the fasting state with the subjects wearing only light clothes and without shoes and BMI was calculated using the equation (BMI = weight (kg)/height (m)2). Patients, of both sexes with mild to moderate essential hypertension (diastolic blood pressure [DBP] >80 and ≤100 mmHg after a 2-week wash-out period, SBP systolic blood pressure>120 and 160 mmHg). Patients were randomly assigned into two groups using a computer-generated random number: Group I treated with valsartan (160 mg/d, n = 100), Group II amlodipine (10 mg/d, n = 100). Another 30 healthy subjects are enrolled as control group (Group III). Subjects in group I and II were asked to maintain their usual dietary and physical activity habits throughout the study. Treatment tolerability was assessed at each follow-up visit.

结局指标
主要结局
Concentration of Adiponectin (pg/ml)
时间窗: three months
Adiponectin is an adipocyte-secreted protein that circulates in the serum
LV mass index (g/m2)
时间窗: three months
Left ventricular mass index (LVMI) is a parameter used in echocardiography cardiac MRI. LVMI is calculated using the following equations: LVMI = LVM (left ventricular mass/body surface area left ventricular mass = 0.8{1.04\[(\[LVEDD + IVSd +PWd\]3 - LVEDD3)\]} + 0.6 Where LVEDD = LV end-diastolic dimension (mm) IVSd = interventricular septal thickness at end-diastole (mm) PWd = posterior wall thickness at end-diastole (mm)
Concentration of Leptin (ng/ml)
时间窗: three months
Leptin is a hormone secreted from fat cells that helps to regulate body weight.
Concentration of TNF-α (pg/ml)
时间窗: Three months
Tumor necrosis factor (TNF or TNF-α) is a major pro-inflammatory cytokine involved in early inflammatory events.
Concentration of hs-CRP (mg/L)
时间窗: Three Months
High sensitivity C-reactive protein a biomarker of inflammation and cardiovascular disease risk.
