Active clinical trials for "Hypertension"

This study to obtain pilot data on Nocturnal Hypertension and Nocturia. In Dr. Victor's current NIH grant (Cut Your Pressure Too: The LA Barbershop Blood Pressure Study) the results show that uncontrolled systolic hypertension is independent determinantal of nocturia in African American men. We now went to pursue this correlation by designing a new NIH grant Proposal to determine whether replacing short acting with long acting drugs and dosing them at bed time rather than in the morning will: A. Lower the systolic Blood pressure during sleep B. Improve Nocturia and results in better sleep quality. The results suggest that short acting hydrochlorothiazide may contribute to nocturia in some patients.

Blood Pressure Lowering Effects of Amosartan Regarding Proviso in Patients with Hypertension

Systemic sclerosis (SSc, also known as scleroderma) is a disease characterized by fibrosis of the skin and organs, inflammation, and an abnormal endothelial cell lining inside of vessels. A common and deadly complication of SSc is pulmonary hypertension (PH), which is an abnormal elevation in the blood pressure within the lung blood vessels. Early identification and treatment of PH is important in SSc, and no clinical factors can predict which patients will develop PH with acceptable accuracy. A potential marker of PH in SSc is the presence of increased amounts of endothelial microparticles (EMPs), which are substances circulating in the blood that were released from damaged vessel wall endothelial lining. A main goal of this study is to investigate if there is a difference in EMP levels between SSc patients with and without PH. The investigators will also use human endothelial cells in a lab environment to test whether these EMPs isolated from SSc patients are actually causing damage to the vessel lining. Lastly, the investigators will investigate the potential benefit of a medication used after transplant, mycophenolate mofetil (MMF). This will be done by causing damage to isolated human endothelial cells and treating them with MMF. The main goal of this portion of our study is to see if EMP levels are reduced when cells are treated with MMF. Overall, the investigators anticipate the following outcomes of this study: 1) use EMP levels to differentiation patients with SSc who have PH from those without PH, 2) use EMPs to understand how endothelial damage occurs in SSc, and 3) use EMPs to help us develop new treatments for patients with vascular diseases.

The kidney plays a crucial role in maintaining salt balance by two opposing physiological mechanisms: the renal dopaminergic system which enhances salt excretion and the renin-angiotensin system (RAS) which causes salt retention. Salt-sensitive hypertension occurs when this balance is altered or abnormal. We hypothesized that this balance is influenced by salt intake: therefore dietary salt affects the natriuretic response to the renal dopaminergic agonist Fenoldopam, and the Angiotensin Converting Enzyme inhibitor, Enalapril. In this trial we study normal salt balance mechanisms in salt resistant adults with normal blood pressure.

This observational study is designed to evaluate the effects of Twynsta tablets with life style modifications on blood pressure, quality of life, and other risk factors in Korean patients with hypertension in a routine clinical practice setting.

The objective of this phase IV clinical multi-center trial will be to compare the efficacy and safety of Ganforti® versus Krytantek®, using a cross-over design during a six month period (including a one-month wash-in period) in POAG and OH patients.

The purpose of this study is to determine whether in pre-hypertensive and hypertensive states such as white coat hypertension, obesity related hypertension or resistant hypertension, renal function is more sensitive to orthostatic stress.

Sodium-related claims on food labels should help people find lower sodium food choices; however consumer attitudes and understanding of such claims are unknown. The objective of this study was to evaluate: 1) the attitudes and understanding to different types of permitted sodium claims and 2) the effect of hypertension on responses to such claims.

Medical devices are designed and manufactured by subjective design process that was only based on engineers' direct concepts to essential principles sets for the device. A home user may not easily use or operate the piece of medical device through the interfacing components as the designer's expected such as the meaning when pushing a button or switching a knob, even the required procedure needed when a certain display shown to fulfill some knowledge dependent judgment. In addition, the incompatible interfacing designed communication between a user and the device may cause possible errors that may trigger further negative consequences during the use of the device to a innocent home user. The aim of this research is to closely understand the consequent results of human factor engineering or usability engineering practices of various types or models of marketed home-use blood pressure monitors (BPM) in real use.

This post-marketing surveillance study was designed to supplement under conditions of normal clinical practice the data on the safety, tolerability and efficacy of Micardis® collected during the clinical studies.
