Structural remodeling of pulmonary artery plays an important role in maintaining sustained pulmonary arterial hypertension (PAH). The anti-remodeling effects of statins have been reported in systemic hypertension. In this study, we studied the effects of atovastatin (Ato) or losartan (Los) in monocrotaline (MCL)-induced pulmonary artery remodeling using a(More)
The aim of this study was to investigate the inhibition capacity of telmisartan to endothelial inflammation induced by homocysteine (Hcy) and discuss the proposed mechanism in vitro. Human umbilical vein endothelial cells (HUVECs) were prepared by collagenase digestion and cultured in vitro. An increase in monocyte chemoattractant protein-1 (MCP-1) and(More)
INTRODUCTION We investigated the association between echocardiographic (Echo) left ventricular mass (LVM) indexed to body surface area (LVM/BSA) or height(2.7) (LVM/H(2.7)) and electrocardiographic (ECG) variables in 546 Chinese hypertensives. METHODS The study group was stratified by gender and by BMI into obese (BMI > or =28 kg/m(2)), overweight (BMI >(More)
Recent epidemiological evidences indicates a complex association of hypertension with vascular endothelial dysfunction which causes the development and progression of atherosclerosis leading to adverse cardiovascular and cerebrovascular events due to reduction in nitric oxide (NO) bioavailability. The aim of the study was to investigate the value on(More)
OBJECTIVE Endothelial function is of prognostic importance for hypertensives. The aim of this study was to investigate the effects of irbesartan combined with diltiazem on the endothelium-dependent vasodilatation in essential hypertensive (EH) patients in China. METHODS A total of 150 Chinese hypertensives aged from 40 to 80 years old were assigned into(More)
BACKGROUND AND OBJECTIVE Apelin is a bioactive peptide manifesting a potent vasodilatory property. In this meta-analysis, we aimed to investigate for the first time whether circulating apelin differed significantly between hypertensive patients and normotensive controls. METHODS Both PubMed and Embase were searched for eligible articles. Eligibility(More)
This study examined the effects of preventive atorvastatin (Ator) treatment on vasodilatation of small pulmonary arteries (SPAs) in monocrotaline (MCT)-induced pulmonary hypertensive rats. SD rats were randomly assigned to: normal control (Ctr), pulmonary arterial hypertension (PAH), PAH treated with 5 mg/kg/d Ator (LAtor), or 10 mg/kg/d Ator (HAtor). PAH(More)
AIMS To study the changes of the metabolic profile during the pathogenesis in monocrotaline (MCT) induced pulmonary arterial hypertension (PAH). METHODS Forty male Sprague-Dawley (SD) rats were randomly divided into 5 groups (n = 8, each). PAH rats were induced by a single dose intraperitoneal injection of 60 mg/kg MCT, while 8 rats given intraperitoneal(More)
OBJECTIVES This meta-analysis was prepared to synthesize published data on the association of two polymorphisms (T45G and G276T) in adiponectin-encoding gene (ADIPOQ) with hypertension risk and the changes of circulating adiponectin and blood pressure. Methodology and Major Findings: Data were collected and corrected by two authors, and were managed with(More)
OBJECTIVES This meta-analysis of randomized parallel controlled trials was designed to compare the efficacy of atenolol with angiotensin-converting enzyme inhibitors (ACEIs) in changing pulse wave velocity (PWV), peripheral blood pressure and heart rate (HR) among patients with essential hypertension. METHODS This study was conducted according to the(More)
