1. Study name: Efficacy and safety of a single-pill fixed combination of sufficient losartan/hydrochlorothiazide in Chinese hypertensive patients (FOCUS) 2. Medicine: Losartan 100 mg/hydrochlorothiazide 25 mg single-pill fixed combination; amlodipine besylate tablet (5 mg/tablet); hydrochlorothiazide tablets (25 mg/tablet) 3. Rationale: Angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) combined with thiazide diuretic (DIU), which is the preferred combination for most hypertension guidelines. However, the efficacy and safety of losartan 100 mg/hydrochlorothiazide 25 mg single-pill fixed combination evaluated by ambulatory blood pressure are still lack of clinical evidence. 4. Objective: To evaluate the efficacy and safety of losartan 100 mg/hydrochlorothiazide 25 mg fixed combination for ambulatory blood pressure after 8 weeks therapy in patients over 18 years with grade 1 or 2 hypertension either newly diagnosed or with blood pressure not controlled with monotherapy. 5. Study design: This study is a multi-center, randomized and controlled clinical trial with two equally sized treatment groups: losartan/hydrochlorothiazide single-pill fixed combination and amlodipine/hydrochlorothiazide. 6. Study population: Men and Women aged over 18 years (n=180) meeting the inclusion/exclusion criteria. 7. Randomization and treatment: Patients should receive a 24-hour ambulatory blood pressure monitoring measurement before randomization. After stratification by centers, eligible patients will be randomly divided into two groups, taking losartan 100 mg/hydrochlorothiazide 25 mg fixed combination once a day or amlodipine besylate tablets (5 mg/tablet) + hydrochlorothiazide tablets (25 mg/tablet) once a day. 8. Follow up: 8 weeks. 9. Sample size: a total of 180 patients should be enrolled in the combination. 10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in September 2018, recruitment will start. Patients enrollment will be performed between October 2018 to August 2024. All patients should be followed up before August 2024.

NCT06900101
During the first week after an acute cerebral injury, neurologic clinical exam is often irrelevant, limited by sedation use or spontaneous consciousness disorders. Hence, neurological monitoring of brain oxygen consumption, metabolic disorders, electrical activity is used to follow and prevent delayed cerebral injuries. Among those instruments, numerous are often described: intra cranial pressure monitoring, brain tissue oxygen pressure monitoring, scalp electroencephalography, continuous electroencephalography and Near infrared Red Spectroscopy (NIRS). Even if the value of some of those technologies are well known, many remain part of a research domain. Here we will not only try to study the correlation between different cerebral autoregulation's index described in the scientific literature but also will we try to identify and describe EEG and cardiorespiratory changes during the first week following brain injury. The objective of this study is to investigate the pathophysiology of acute brain injury and explore potent biomarkers of multimodal monitoring during the first week following acute brain injury.

Participants were divided into three groups and their blood pressures were measured in the left lateral, right lateral and semi-Fowler positions. Data were collected using an introductory information form and the State Anxiety Scale.
NCT05258890
This study aims to compare the efficacy of a social network intervention versus individual hypertension counseling to improve blood pressure control after stroke. The investigators hope to understand whether the involvement of family, friends and other members of individual's social network can help achieve better blood pressure after experiencing a stroke. Participants will be stratified to two groups according to network size (\<5 vs 5 or more) and randomized to receive individual hypertension counseling (control) or the social network intervention. The primary outcome of the study will be the absolute reduction in systolic blood pressure at 3 months follow-up. The secondary outcomes will be attainment of a post-stroke hypertension treatment goal and patient-reported physical function.

The burden of hypertension and related cardiovascular diseases, stroke, and end-stage kidney disease is disproportionately high in Black populations, especially in the South. The Blood Pressure Lowering Strategies to Eliminate Hypertension Disparities (BLESSED) cluster randomized trial aims to test the effectiveness, implementation, and sustainability of a community health worker (CHW)-led multifaceted intervention compared to enhanced usual care for hypertension control in Black communities. In the BLESSED trial, the investigators plan to recruit 1,176 adults with hypertension (approximately 28 per church) from 42 predominantly Black churches in the Greater New Orleans area. The multifaceted intervention will last for 18 months, followed by a post-intervention follow-up visit at 24 months. The BLESSED trial aims to generate evidence regarding the effectiveness, implementation, and sustainability of this CHW-led church-based multifaceted intervention in eliminating hypertension disparities in the United States (US) general population.
NCT06890169
The goal of this clinical trial is to learn if the use of a care model including teleconsults and the EMPOWER app can induce clinically significant weight loss and metabolic improvements in obese adults with diabetes and metabolic dysfunction-associated steatotic liver disease (MASLD). Researchers will compare this model with the conventional standard of care of physical visit-based weight management program to see if this model is non-inferior to the standard of care for inducing weight loss, and if there is greater patient convenience with telehealth and more frequent self-monitoring, compliance with diet advice and exercise participation compared to standard of care. Participants in the standard arm will attend 4 physical doctor and 4 physical dietician consultations over 26 weeks, where they will be provided with an individualized diet and exercise prescription to induce at least 5% weight loss. Participants in the intervention arm will have the same number of consults over 26 weeks, of which at least 50% will be teleconsults, and will also be provided with an individualized diet and exercise prescription to induce at least 5% weight loss. In addition, they will be taught to use the EMPOWER app to upload weight, blood pressure and glucose, food and exercise records which will be reviewed at the consults. The app also delivers nudges to improve adherence to lifestyle modification.

NCT06865118
The goal of this observational pilot trial is to evaluate the feasibility of home monitoring for patients with systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH). The study will assess home-based measures that may help detect disease progression earlier and will also evaluate patient satisfaction, usability, and the impact on health-related quality of life. The study aims to answer: * How feasible is home monitoring in SSc-PAH patients in terms of adherence, technical feasibility, and validity of home-based measures? * How do home-based assessments compare to hospital-based assessments in detecting disease progression? * How do patients experience digital home monitoring? Participants will: * Use a digital platform (Zeen Health) for biweekly self-reporting of symptoms and physiological measurements. * Perform functional tests at home, including the 1-minute sit-to-stand test (1MSTS). * Wear the ECG247 Smart Heart Sensor for one week to monitor heart rhythm. * Collect and submit home blood samples every two weeks. * Attend two hospital visits (baseline and week 12) for clinical assessments, functional testing, pulmonary function tests, echocardiography, and routine blood sampling for clinical assessments. This 12-week study will assess the feasibility of home monitoring, as well as the validity and reliability of home-based measures. The findings will help design a future study aimed at integrating home-based assessments into routine clinical care.
NCT03683069
Salt sensitivity of blood pressure is a substantial risk factor for cardiovascular morbidity and mortality. Inappropriate increases in renal sodium reabsorption lead to volume expansion, hypertension and salt sensitive blood pressure. Key homeostatic mechanisms that regulate renal sodium reabsorption are: first, hormonal, e.g., renin-angiotensin-aldosterone system and second, vascular, e.g., renal vasculature. Dysfunction in one or both mechanisms leads to hypertension and salt sensitive blood pressure. The investigators recently documented that striatin plays a novel role in the development of salt sensitive blood pressure. However, the mechanisms that lead to striatin-mediated salt sensitive blood pressure are not clear; defining these mechanisms is the overall goal of this proposal. Striatin is a calmodulin- and caveolin-binding protein that can function as either a scaffolding and/or signaling protein, specifically in relation to the mechanism of action of steroids. In a large study of well characterized subjects from the International Hypertensive Pathotype (HyperPATH) cohort, the investigators documented that hypertensive and normotensive humans who are striatin risk allele carriers have salt sensitive blood pressure. The investigators then developed a striatin heterozygous knockout mouse as a tool to identify potential mechanisms for the salt sensitive blood pressure. The investigators documented that these mice also have salt sensitive blood pressure with higher blood pressure levels and inappropriately increased aldosterone levels on a liberal salt diet.

Wearable health technology, particularly smartwatches, has revolutionized personal health monitoring by enabling continuous, non-invasive tracking of various physiological parameters. The potential applications of these devices in cardiology are extensive, but it is crucial to validate their accuracy against established medical-grade devices. The Apple Watch Series 9 (Apple, USA) exemplifies the capabilities of modern smartwatches, offering a wide range of health tracking features. These include heart rate monitoring, detection of irregular heart rhythms suggestive of atrial fibrillation, electrocardiogram recording, blood oxygen level measurement, and comprehensive mobility metrics (including VO2 max, six-minute walk distance, walking speed, step length, double support time, and walking asymmetry). Many of these parameters are highly relevant for cardiovascular patients, potentially aiding in disease progression monitoring and adverse event prediction. However, there is a lack of comprehensive validation studies for these devices in specific cardiovascular disease populations. This investigator-initiated prospective observational study involving 50-100 participants that aims to validate smartwatchbased assessments using medical-grade devices and techniques. The study will focus on adult patients with congenital heart disease, pulmonary hypertension, heart failure, and coronary artery disease, as well as athletes undergoing cardiovascular assessment. By comparing smartwatch data with established clinical measurements, the investigators seek to determine the reliability and potential clinical utility of these wearable devices in diverse cardiovascular contexts. This research will help bridge the gap between consumer-grade wearable technology and clinical practice in cardiology.

NCT06759805
In Norway, more than 11,000 patients undergo percutaneous coronary intervention (PCI) annually. However, a very recent study utilizing registry data show a national average of cardiac rehabilitation (CR) participation of only 14%, despite its proven beneficial effects on readmissions, physical capacity, psychological distress, self-management, and quality of life. CR is strongly recommended in European guidelines. However, uptake is low and is not systematically identifying those in most need of CR. The primary objective of eCardiacRehab is to meet rehabilitation needs of large patient populations regardless of their access to traditional place-based rehabilitation by developing and evaluating the efficacy and cost effectiveness of an interdisciplinary and comprehensive home-based eCardiacRehab programme. eCardiacRehab address patient- and system level challenges in order to increase access to CR. The investigators give particular attention to older patients, women, and those with comorbidities or mental health challenges. Aspects related to continuity of care between specialist and primary care services, health literacy, adherence to treatment, cost effectiveness and ethics are investigated. The investigators will 1) continue to develop the programme with patients, general practitioners, healthcare experts from both specialist and primary care services, and technology developers, 2) develop treatment modules, 3) establish information and communication infrastructure, 4) evaluate the process and efficacy of treatment modules, 5) ensure knowledge development and transfer of competence to the municipalities, and 6) contribute to fulfil the innovation potential for health service and industry partners. eCardiacRehab has the potential to improve interaction and collaboration between primary and secondary care, modernise and digitalise work processes, and develop more coherent and tailored patient pathways. The vision of the home-based eCardiacRehab is to make CR available to all.
