Active clinical trials for "Hypertension"

Some studies have shown that the main pathogenesis of patients with covid19 is related to ACE2 receptor. Lung is one of the main organs, and there are many ACE2 receptors in cardiovascular system. ACEI / ARB is the main target of antihypertensive drugs. Previous reports suggested that there were large number of patients with covid19 also suffered from hypertension, suggesting that patients with hypertension may be the susceptible to covid19. Therefore, we try to follow up the patients admitted to Hankou hospital to explore the impact of hypertension and hypertension treatment on the severity and prognosis of patients with covid19, so as to provide new methods for the treatment of patients with covid19 in the future.

Systemic arterial hypertension (SAH) has a direct association with endothelial dysfunction and major cardiovascular events. Evidence points to possible benefits of aerobic training in the endothelial function analyzed by the flow mediated dilation technique (flow mediated dilatation - FMD) in individuals with SAH. However, little is known about the influence of the autonomic nervous system (ANS) on the results of brachial artery FMD after different types of acute exercise in individuals with SAH. Thus, the objective of the research is to analyze the influence of the ANS on the FMD of the brachial artery of individuals with SAH after a session of aerobic (EA), resistance (ER) and combined (EC) exercise. For this, thirty-nine hypertensive individuals aged 35 to 55 years will be recruited and will be randomized to 2 sessions of AS, ER or EC. Also, within each modality, they will be randomized to α1-adrenergic block (Doxazosin 0.05 mg / kg-1) or placebo. The FMD will be performed by ultrasound 10 minutes before, as well as 10, 40 and 70 minutes after the exercise sessions and the autonomic control will be monitored (Finometer) for 10 minutes before each FMD. Arterial stiffness will also be analyzed, using the pulse wave velocity (PWV) by the Complior Analyzer. It is expected to demonstrate with this research the influence of the ANS on the FMD of the brachial artery in individuals with SAH in different physical exercises. This knowledge contributes to a better training prescription in this population.

Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.

The dietary shift from animal to plant protein sources is one of the key aspects of the nutritional transition towards more sustainable food system and diets. However the metabolic implication of this shift in protein sources are still poorly understood. This project aims to characterize and understand the metabolic orientations specifically induced by animal and vegetable dietary proteins, in order to better analyze the metabolic reorientations that would result from the expected increase in the share of plant proteins in different dietary contexts, especially those of the Western type, often associated with the development of metabolic deregulations (obesity and cardiometabolic risk).

In June 2016, the Health Reform Office in the State Council released "the Announcement about Guiding Opinions of Promoting Family Physician Contract Services". Family Physician Contract Service is an important tool to change the health service models in primary care organizations in China. The relationship between patients and physicians can be regarded as principles and agents. Physician agency theory has been used to study physician behaviors in economics and management. Family physician contract services regulate the principle-agent relationship between patients and physicians using a formal contract, and there are lots of potentials to employ the physician agency theory to study family physician contract services in China. In theoretical aspects, the present project will study the analysis frameworks and methods of family physician contract services in China under the capitation and global budget payment mechanisms after systematically reviewing Chinese and English literatures about the physician agency theory. In empirical aspects, the present project will collect data from family physician contract services and examine the effects of specific contract forms, incentives, and fees on family physician behaviors and their impacts on health status and medical expenditures of hypertensive and diabetic patients.

Evaluation of anthropometric, clinical and biological profile in four groups that represents transversely the natural history of Obstructive Sleep Apnea (OSA) and its associated cardiovascular comorbidities: non-OSA, OSA without hypertension, OSA and with hypertension and OSA with a cardiovascular event (CVE).

Background: Traditional office blood pressure (BP) measurement is often inaccurate and is inferior to out-of-office measurements, such as ambulatory blood pressure monitoring (ABPM), in predicting cardiovascular outcomes. A relatively new BP measurement method, called Automatic Office Blood Pressure measurement (AOBP), may provide similar BP readings to ABPM (latest clinical gold standard for BP measurements) and can easily be conducted in clinics. AOBP machines measure BP repeatedly 3-5 times with 1-min intervals and automatically provide the mean BP value. While AOBP was used in landmark trials (e.g. SPRINT trial) and was shown to eliminate white-coat effect, AOBP is rarely used in Hong Kong partly because there is no data concerning the accuracy of AOBP in Chinese. Almost all previous AOBP research used BpTRU (AOBP model), but BpTRU manufacturer was shut down permanently. Aim: To assess if WatchBP Office (another AOBP model) has superior diagnostic accuracy than traditional office BP measurements, when compared to ABPM readings. Method: 150 Chinese adult patients with a diagnosis of essential hypertension will be recruited consecutively from a Government-funded primary care clinic. All patients will have their BP measured by a 48-hour ABPM, a WatchBP office, and two traditional office blood pressure measurements. ABPM will be considered the gold standard; sensitivity, specificity, positive and negative predictive values of AOBP and traditional BP to diagnose elevated BP level, masked hypertension and white-coat hypertension will be calculated and compared Implication: if WatchBP provides closer BP readings to ABPM, this can lead to its implementation in routine clinical practice

This project was a facility-based program intervention for People Living with HIV (PLHIV) aged 18 years and above who attended a Care and Treatment Center (CTC) in Dar es Salaam, Tanzania. Clients received preventive, diagnostic, and treatment services for Hypertension (HTN) and Type Two Diabetes Mellitus (T2DM). The primary health outcomes were all-cause mortality, disease-specific morbidity, HTN, and T2DM control rates. Secondary outcomes included access to care, retention in care adherence, and quality of care. Results obtained can be used to strengthen Non-Communicable Diseases (NCDs) care delivery in HIV/AIDS care in CTC in Tanzania.

This study plans to learn more about activity levels in children with pulmonary hypertension. Pulmonary hypertension is a condition where the pressure in the lungs is higher than normal. This can affect the person's heart. The purpose of this study is to see if measuring activity in children with pulmonary hypertension and comparing it to activity in children without pulmonary hypertension can give their doctor helpful information on how they are feeling and how their treatment is working.

The investigators will conduct a pragmatic pilot test of a remote patient monitoring system (RPM) for blood pressure measurement for Medicare patients with hypertension. The primary objective is to better understand how patients' remote monitoring of blood pressure and the direct transmission of this data to a healthcare system's EHR can be used by the patient and the care team to support optimal hypertension care. This pilot study which we will conduct in two Northwestern Medical Group (NMG) primary care practices will: evaluate the integration of Omron's remote monitoring system into Northwestern Medicine's electronic health record (so that clinical data can flow directly from the patient's monitor to the EHR), evaluate the use of billing work flows for covered Medicare services, build and deploy clinical decision support to aid with patient identification and ordering of the remote patient monitoring system, and evaluate the uptake and clinical effects of this system in the pilot practices compared to matched patients selected from non-pilot control practices. The investigators will conduct a pragmatic non-blinded, non-randomized pilot study with contemporaneous controls among NMG outpatient clinics that provide adult primary care. They will make comparisons of data obtained through the course of routine care delivery from pilot and non-pilot practices.
