Active clinical trials for "Hypertension"

The purpose of this study is to test the theory that a major factor in poor blood pressure (BP) control is that physicians fail to intensify antihypertensive therapy for their patients.

This study will test the separate and combined effects of a continuous quality improvement (CQI) intervention for physicians (MDs) and a behavioral intervention for patients on blood pressure control.

This study will evaluate the efficacy and safety of valsartan and amlodipine in fixed dose combination in adults with moderate, inadequately controlled hypertension. There was an optional study extension for eligible patients who wanted to participate that contains the triple therapy (ie, hydrochlorothiazide+ amlodipine/valsartan).

Efficacy and safety evaluation of Combigan with timolol when each is used as adjunctive therapy to Xalatan in subjects with glaucoma or ocular hypertension.

While the use of herbals is increasing considerably, their efficacy and safety in the humans remains largely unknown. This surge in demand prompts a call for its evaluation. Preliminary data demonstrates that KRG can affect vascular function and our research group has previously shown that Korean Red Ginseng (KRG) can lower blood pressure (BP) in hypertensive individuals. However, it is unknown which dose is the most effective in producing a desired effect. To address this issue, we will test escalating doses of a single Korean red ginseng batch of 0.5g, 1g 3g and 6g on BP in patients with hypertension to determine the most efficacious dose. The most promising dose will be extracted and will advance to next level to be tested again on BP control. The findings of the study may result in better ginseng standardization.

Intervention description: Complementary Approaches to Lower Mean arterial pressure (CALM) is a multi dispensary program aimed to reduce blood pressure in hypertensive patients. The program utilizes a naturopathic dietary approach, education on cooking and food consumption choices, walking physical exercise, Qi Gong - a form of Chinese slow movement exercise combined with relaxation breathing and imagery and group therapy coaching in stress management techniques and mind-body balancing techniques. Trial Objectives: To compare the effect of CALM in reducing blood pressure to the standard dietary DASH approach in hypertensive patients. Methodology: 120 Participants will be randomly assigned in to two groups: CALM program for reducing blood pressure as the treatment group. Standard DASH diet and lifestyle modification counseling as the control group. Inclusion Criteria Adult men and women over 18 years. Patients using anti hypertensive medications with mean systolic blood pressure measurements of 120-180 mm Hg and/or mean diastolic measurements of 70-100 mm Hg as determined by a 24 hour Holter test. Patients not using anti hypertensive medications with mean systolic blood pressure measurements of 130-180 mm Hg and or mean diastolic measurements of 80-100 mmHg. Signed informed consent (appears in IRB forms) Assessment of Efficacy Primary end point efficacy will be assessed by comparing the mean BP measurements in the CALM group to the mean BP measurements in the DASH control group. Blood pressure measurements will be performed by 24 hours Holter BP monitoring in the beginning and at the end of the trial. Secondary end points efficacy will be assed by comparing CALM to DASH programs with respect to effects use of BP medications and weight loss. Lab test and pulse wave analysis will also be assessed at the beginning and at the end of the study.

A clinical trial to compare the pharmacokinetic and safety of CKD-828

Profound and concomitant cardiovascular hemodynamic changes, necessary to support fetoplacental development and its increasing supply demands, occur during a physiological pregnancy characterized by an increase in cardiac output, heart rate and plasma volume, and fall in vascular resistance and blood pressure. The result of these changes is a volume overload that will lead to a compensatory transient left ventricular eccentric hypertrophy. This, together with the pro-inflammatory state typical of pregnancy, represents the pregnancy as a stress-test for the maternal cardiovascular system. Pregnancies complicated by hypertensive disorders of pregnancy (HDP), particularly those with early onset and/or complicated by intrauterine fetal growth restriction (FGR), are characterized by a cardiovascular maladaptation. Women who experienced HDP in pregnancy, especially pre-eclampsia (PE), more often develop later in life ischemic heart disease, hypertension and stroke, obesity, dyslipidemia, and end-stage renal disease. Regardless its clinical impact, very little knowledge is available on the mechanisms by which PE could lead to cardiovascular disease (CVD), and, especially, to heart failure after pregnancy. Preliminary results suggest a cross-talk between pregnancy-induced biomarkers and cardio-vascular system. Particularly, cultures of neonatal rat cardiomyocytes and fibroblasts were used to investigate the role of the serum of women with HDP in regulating their proliferation. 5-ethynyl-2'-deoxyuridine (EdU) was administered to label DNA synthesis in proliferating cells. After 3 days of in vitro culture, EdU incorporation was analyzed upon immunofluorescence staining using specific antibodies by high content microscopy. A possible protective effect exerted by the selected sera against apoptosis was evaluated, as well, by Caspase activation. Moreover, the effect of cardiomyocytes and fibroblasts proliferation and apoptosis on maternal hemodynamic parameters was evaluated using median regression models. These data show that the serum of women with HDP triggers a net increase in the percentage of proliferating cardiomyocytes compared to controls. Moreover, there were relationship between cardiomyocytes and fibroblasts proliferation and maternal hemodynamics parameters thus, supporting the hypothesis that the serum of women with HDP may contain factors capable of stimulating cardiac cells in response to the cardiovascular stress-test

The goal of this study is to compare the characteristics of baxdrostat (CIN-107) in terms of baxdrostat levels over time in the blood in healthy Japanese and Caucasian volunteer participants.

Obesity in adolescents is associated with the development of cardiovascular disease and type 2 diabetes mellitus. In order to detect early development of cardiovascular disease, early detection of the endothelium of obese adolescents is needed. Endothelium dysfunction is an early stage of developing atherosclerosis, which can be a predictor of cardiovascular disease development in the future. Flow mediated dilatation (FMD) is a non-invasive method that can measure endothelium function and predict the risk of cardiovascular disease, which is not only able to measure artery diameter, but also provides function index of nitric oxide (NO) in the endothelium. FMD is negatively related to BMI. Meanwhile, Endothelin-1 (ET-1) is thought to play a role in the pathogenesis of insulin resistance, because when its levels increase, ET-1 can cause a condition of hyperinsulinemia. ET-1 was found to be high in patients with cardiovascular disorders, as well as in obese and diabetic subjects. Alternative methods for assessing endothelial function by measurement of biomarkers of activation and endothelial dysfunction such as soluble intercellular adhesion molecule-1 (sICAM-1). Levels of sICAM-1 have been found to be related positively to age, systolic and diastolic blood pressure, hypercholesterolemia, hypertriglyceridemia and inversely to estrogen. Furthermore, associations have been found between sICAM-1 and cardiovascular mortality in both healthy individuals and populations at high risk. The aim of the study was to evaluate FMD, concentrations of ET-1 and sICAM-1 in adolescents with a presence of obesity and hypertension and to compare these with controls (obesity and non hypertension), as well as to analyze the correlations between FMD, ET-1, sICAM-1 and blood pressure values.
