Ficus deltoidea is used in Malay traditional medicine for the treatment of a number of disorders, including hypertension. There is, however, no scientific evidence on its anti-hypertensive effects. This study, therefore, investigated the effects of a standardized ethanolic-water extract of Ficus deltoidea Angustifolia (FD-A) on blood pressure (BP) in spontaneously hypertensive rats (SHR). Male SHR with systolic BP of >150 were divided into 4 groups (n = 8) and given either FD-A (800 or 1000 mg kg-1 day-1 ) or losartan (10 mg kg-1 day-1 ) or 0...

BACKGROUND: Maximum home systolic blood pressure (maximum SBP) has been reported as a parameter of blood pressure (BP) variability. We tested the hypothesis that maximum SBP is one of the risk factors of hypertensive target organ damage (TOD). METHODS: We conducted a cross-sectional study of 4,310 subjects with 1 cardiovascular risk factor. The subjects measured their home BP for 14 consecutive days. Mean and maximum SBPs were used as independent variables. As dependent variables, we used left ventricular mass index (LVMI), brachial-ankle pulse wave velocity (baPWV), maximum carotid intima-media thickness (CIMT), and urine albumin creatinine ratio (UACR)...

The isometric handgrip training (IHT) has been emerging as an alternative approach for blood pressure (BP) reduction in hypertensive patients. However, the mechanisms underlying the reductions in BP after IHT are poorly known. Thus, the aim of this study was to analyze the vascular effects of IHT in hypertensive patients. A randomized controlled trial was conducted with 33 hypertensive patients (61 ± 2 y.o.; 67% female) who were randomly assigned to two groups: IHT or control group. The IHT group has completed three weekly sessions of isometric handgrip (4 × 2  min sets, alternating the hands at 30% of maximal voluntary contraction)...

BACKGROUND AND PURPOSE: Human chymase (h-chymase) is a serine protease that forms local angiotensin II and has been proven to be related to onset of hypertension, arteriosclerosis, and post myocardial infarction cardiac remodeling. Since no chymase inhibitor was clinically available, an extensive screening for inhibition of h-chymase in three different extracts (water, hot water,  and ethanol) of approximately 800 food ingredients had been performed and we identified Polygonum hydropiper L (Polygonum)...

OBJECTIVE: Smoking is a modifiable cardiovascular risk factor closely related to arterial stiffness (AS). However, data are lacking regarding the chronic effects of smoking on AS, especially in ex-smoker (ES) who faces remnant cardiovascular risk when compared to never-smokers (NS). METHODS: Among 1722 health screening participants, we retrospectively evaluated 652 healthy men with different smoking history [240 current smoker (CS) vs. 228 ES vs. 184 NS]. To assess AS, augmentation index (AIx), pulse pressure amplification (PPamp), and carotid-femoral pulse wave velocity (cfPWV) were measured and compared...

BACKGROUND: Since the introduction of leptin, many studies suggest an important role for this hormone in obesity-related hypertension. However, in non-obese patients, there are controversial results regarding the possible role of leptin in essential hypertension especially in both sexes and different groups of body mass index (BMI). We aimed to evaluate the association of leptin and hypertension in both female and male gender. MATERIALS AND METHODS: This cross-sectional study was conducted, recruiting 80 essential hypertensive patients and 80 healthy normotensive volunteers using convenience sampling method...

BACKGROUND AND OBJECTIVES: Essential hypertension is a complex progressive cardiovascular disorder. Renin-angiotensin aldosterone system (RAAS) plays a major role in blood pressure regulation. Aldosterone, synthesized in the adrenal cortex by aldosterone synthase is encoded by the CYP11B2 gene. This case-control study was aiming to investigate the relationship between the aldosterone synthase gene (CYP11B2) biallelic polymorphism in the promoter at position -344 (-344C/T) with essential hypertension and left ventricular hypertrophy in the Egyptian population...

BACKGROUND: Carotid-femoral pulse wave velocity (PWV) is a direct measure of aortic stiffness used in the stratification of cardiovascular risk. Its clinical application in Latin America has been limited by the absence of reference values. The objective of this study was to establish PWV reference values among adults referred to a specialized cardiology center for 24-hour ambulatory blood pressure monitoring (ABPM) in Medellín, Colombia. METHODS: A descriptive study of 3,160 records of adult (older than 18 years) patients without pharmacological treatment assessed for PWV using a Mobil-O-Graph® 24-hour PWA device (IEM, Stolberg, Germany) and 24-hour ABPM with hemodynamic parameters based on suspected hypertension or hypotension was conducted...

BACKGROUND: We hypothesized that the 5-oxo-1,2,4-oxadiazole moiety of azilsartan (AZL), which represents a small difference in the molecular structures of AZL and candesartan (CAN) [angiotensin II type 1 receptor (AT1 R) blockers], may be responsible for the molecular effects of AZL. METHODS: We examined the binding affinities of AZL and CAN to AT1 R, along with their ability to block receptor activity. A competition binding study, inositol phosphate (IP) production assay and extracellular signal-regulated kinase (ERK) assay were performed using wild-type (WT) and mutants AT1 R-transfected cells...
