Active clinical trials for "Hypertension"

This study investigated the effect of 12 weeks of aerobic training on sleep quality and aerobic fitness in patients with Pulmonary arterial hypertension(PAH).

To quantitatively analyze the total radioactivity in the excreta of healthy male subjects after oral administration of [14C] SPH3127, and determine the cumulative excretion rate and main excretion routes of radioactive substances; to investigate the partition in whole blood and plasma and the pharmacokinetics of total radioactivity in plasma after a single oral administration of [14C]SPH3127 in healthy male subjects; to identify the main metabolites in healthy male subjects after an oral administration of [14C] SPH3127, determine the main biotransformation pathways and main metabolites, quantitatively analyze the concentration of SPH3127 and main metabolites in plasma by validated LC-MS/MS method, and establish the pharmacokinetic parameters of SPH3127 and its main metabolites in plasma.

Introduction: Endothelial dysfunction precedes atherosclerosis being evidenced in patients with hypertension. Increasing physical activity levels and/or physical exercise are part of the recommendations of antihypertensive therapy. However, the effects of oscillations and/or increase the systemic blood pressure induced by exercise session on endothelial function has not been studied. Objective: To evaluate the effect of aerobic exercise, resistance exercise and combined exercise on endothelial injury levels in patients with hypertension. Methodology: Hypertensive (n = 51) and healthy subjects (n = 30) (30-59 years old) will perform at random 40 minutes of aerobic exercise (50-60% of heart rate reserve) or 40 minutes of resistance exercise (4 x 12 repetitions of exercises for lower limbs, 60-70% of one repetition maximum and 60-90 second interval) or 40 minutes of combined exercise (20 minutes of resistance exercise and 20 minutes of aerobic exercise, in that order). Blood will be collected 10 minutes before, 10 and 60 minutes after intervention for the quantification of endothelial microparticles (MPE) circulating (induced endothelial lesion) and endothelial progenitor cells (EPC) circulating (endothelial recovery capacity) by flow cytometry. Ambulatory blood pressure monitoring (ABPM) will be held before and after the intervention. Ultrasonography is used to measure the flow-mediated dilation of the brachial artery 10 minutes before, 10, 30 and 60 minutes after the intervention. Statistics: generalized estimating equation (GEE) for repeated measurements and Person correlation, being significant p < 0.05. It is expected to show results to ensure cardiovascular protection in patients with hypertension caused by different types of exercise and consequent endothelial injury and release induced regenerative factors. Knowledge of the magnitude of injury and endothelial recovery provided by different types of exercise can contribute scientifically to health professionals aimed at prescribing exercise with a vascular protective vision in patients with hypertension.

research on interactions between portal hypertension and microparticles

By conducting the SPPA trial we try to find out, whether personalized Short Message Service (SMS) reminders of blood pressure-lowering medication can effectively increase patients' adherence to blood pressure-lowering medication. Additionally, we also evaluate their effect on patients' systolic blood pressure control.

The study evaluates the use of automated motivational messages, visit reminders, and medication reminders (using interactive voice response technology or text messages) to improve blood pressure control among adults with hypertension that receive their care at the First Nations Community Healthsource clinic in Albuquerque, New Mexico. Half of the participants will receive usual care, while the other half will receive the automated calls or text messages and have the option to receive home blood pressure monitors and/or designate a care partner who will also receive messages. Participants will be followed for 12 months.

The proposed study "Project IMPACT: CHW Intervention" is part of a larger study examining the efficacy, adoption, and impact of integrated EHR-based decision-support and physician feedback interventions with community health worker (CHW)-led self-management and coaching support for South Asian patients with uncontrolled hypertension. This is a randomized control intervention utilizing community health worker (CHW)-led self-management and coaching support for South Asian patients with uncontrolled hypertension at PCP clinics in New York City.

This study evaluates the effect of a mobile health technology enabled trained nurse led intervention on control of blood pressure among patients with hypertension seeking care in the community health centres in the southern state of Andhra Pradesh, India. half the community health centres will receive the intervention and the other half will receive the routine care.

Control of hypertension remains one of the most important interventions available to clinicians to reduce risk of cardiovascular disease, kidney disease and stroke. Self-measured home blood pressure monitoring plus additional support has been shown to reduce blood pressure in adults with previously uncontrolled hypertension. Most previous studies have utilized healthcare personnel to facilitate communication of home blood pressure levels to physicians and did not provide methods to directly transmit self-measured blood home blood pressure levels to physicians via the electronic health record. Emerging technology now provides the ability for patient's to upload self-measured blood pressure levels into their own medical record which may eliminate the need for additional health personnel. This study will examine the feasibility, patient adherence and physician and patient perceptions of a web-based application which will facilitate direct input of self-measured home blood pressure levels and patient reported symptoms directly into the electronic health record with message alerts to the provider for hypertension management. Up to 10 Loyola primary care physicians and 20 of their respective patients age 50 years and older who have a smart phone device or home computer and have treated hypertension will be enrolled. The study will utilize the existing web-application called MyChart. MyChart is the name of the web-based application and it is not an acronym. Enrolled patients will download the existing MyChart web-based application on their smart phone device or home computer and will record home blood pressure measurements using their home blood pressure machine into their smart phone application. The MyChart application is available to all patients receiving care in the Loyola Health Care System. The blood pressure readings and patient reported symptoms will then be available for their physicians to review within the electronic health record. After using the web-based application for two months, both patients and physicians will be asked to participate in focus groups and interviews, respectively, to determine their perceptions and satisfaction with the web-based application. Data from this feasibility study may be used to guide a future clinical trial of hypertension management that examines the effectiveness of the MyChart web-based application for frequent blood pressure monitoring compared to standard care.

Clinical Trial: The investigators aims at comparing providing validated home BP device, followed by group education of self-management of hypertension as well as self-BP monitoring and appropriate medication in response to home BP reading, followed by nurse follow up with usual care, which may possibly improve patients with uncontrolled hypertensions drug adherence, and therefore improve their BP level in primary care setting. The investigators will invite total 270 patients from 5 general outpatient clinic (GOPCs) to participate the trial. Qualitative study: The investigators would also like to evaluate patients' view and operational concerns on self BP monitoring by individually interviewing 30 selected patients with uncontrolled hypertension
