Filter by:The purpose of this 20-week randomized double-blind study in patients with resistant hypertension (rHTN) is to evaluate the efficacy, safety, and tolerability, of different doses of XXB750 administered as subcutaneous (SC) injections, compared to placebo. Since all study participants will be patients with rHTN, all study treatments will be given on top of maximally tolerated background antihypertensive therapy recommended by international guidelines for treatment of HTN (i.e., a thiazide or a thiazide-like diuretic, an angiotensin converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB), and a long-acting dihydropyridine calcium channel blocker (CCB).
A longer-term follow-up of patients with remote patient monitoring ordered from the initial six pilot primary care clinics (from the prior study periods: Study 1 and Study 2) will be performed and compared to a cohort of patients without RPM orders, matched on clinical and demographic characteristics, from the same six pilot primary care clinics, to serve as contemporary controls.
The apelin-APJ signaling pathway has emerged as an important novel mediator of cardiovascular control and blood pressure homeostasis. Genetic variation in apelin and its receptors likely contributes to essential hypertension, in addition to a range of traditional risk factors. Thus, a study will be conducted on Syrian patients with hypertension and coronary artery disease to investigate some of the single polymorphisms in the apelin gene and its receptor that may be responsible for the development of these diseases, and to link the levels of this peptide and its receptor in the blood with these polymorphisms and the percentage of these diseases (as shown by many Modern Global Reference Studies).
Cardiovascular diseases (CVDs) are the number one cause of death in America and most of the post-industrial world. Hypertension is a leading risk factor for CVDs including stroke, myocardial infarction, and heart failure. Black Americans suffer from the highest rates of hypertension of any racial/ethnic group in America, among the highest in the world. There are also well-documented racial disparities in vascular dysfunction (e.g., endothelial dysfunction, arterial stiffening). Thus, racial disparities in hypertension and vascular dysfunction exacerbate the burden of CVDs, with Black Americans being 30% more likely to die from CVD than any other race in the US. It is established that mitochondrial dysfunction contributes to vascular dysfunction. However, there is a knowledge gap regarding whether targeting mitochondrial dysfunction attenuates oxidative stress, vascular dysfunction, and CVD risk among Black adults at heightened CVD risk. Thus, the investigators will conduct an 8-week trial with the mitochondrial antioxidant MitoQ in middle-aged and older Black and non-Black adults. Our overarching hypothesis is that mitochondrial dysfunction contributes to heightened oxidative stress, vascular dysfunction, and higher BP in Black adults; and that MitoQ will attenuate these racial differences. Importantly, the investigators will also assess social determinants of health (e.g., income, neighborhood disadvantage, discrimination) and health behaviors (e.g., diet, physical activity) and uncover their role in oxidative stress, vascular function, and BP Regarding methodology, the investigators will perform blood draws, vascular testing, preceding and following an 8-week, 20mg daily consumption of MitoQ and placebo. The investigators will also measure urine biomarkers of kidney function and blood pressure in adults (45-75 years old).
Cardiovascular and associated hypertensive diseases are the leading health burden and cause of mortality worldwide; therefore, the necessity for effective interventions is paramount. Dietary interventions to improve cardiovascular health are highly sought after as they possess less risk and financial burden than pharmacological drugs. Our previous randomized trial has shown that oral peppermint can improving systolic blood pressure and other cardiovascular/ blood lipids in healthy individuals. However, to date, no research has explored this using a placebo randomized intervention in patients with hypertension. Therefore, the primary purpose of the proposed investigation is to test the ability of oral peppermint oil supplementation to improve cardiometabolic parameters in participants with mild-moderate hypertension.
IMPAHCT-FUL: Inhaled Imatinib Pulmonary Arterial Hypertension Clinical Trial - Follow Up Long Term Extension (LTE) Trial is a follow up study to establish the long-term safety of AV-101. The long-term effects of AV-101 on efficacy measures will also be assessed. Subjects who successfully complete the 24-week placebo-controlled parent trial (AV-101-002) will be offered the opportunity to continue into this LTE study. Subjects who enroll in the study will receive one of three active AV-101 doses until such time as the optimal dose has been selected in the parent study.
The purpose of this study in patients undergoing routine care epidural spinal cord stimulation (SCS) is to determine 1) whether SCS reduces arterial blood pressure (BP) in patients which chronic low back pain and hypertension, 2) whether higher baseline BP (i.e., hypertension) predicts reductions in pain following SCS, and finally 3) whether different SCS waveforms elicits stimulus-evoked compound action potentials (ECAPs) in spinal cord and at the cortex (electroencephalography, and magnetoenchphalography).
The purpose of this study is to examine the intervention effectiveness and dissemination of digital health care delivery models for improving selected health outcomes in the Medicaid population.
Despite the many associated health benefits, more than half of Veterans do not achieve enough regular physical activity. The investigators' prior work has demonstrated that gamification, a method commonly used for health promotion, can lead to sustained increases in physical activity if it is designed using insights from behavioral economics to enhance social incentives. In this study, the investigators will compare the effectiveness of behaviorally designed gamification that encourages Veterans to collaborate or compete on physical activity levels and examine clinical outcomes as well as costs, barriers and facilitators to implementation of the program within Veterans Affairs.
Chronic obstructive pulmonary disease (COPD) is a disease of the lungs that makes it hard for people to breath. Those with COPD spend considerably more time sitting and lying and less time performing physical activity than healthy individuals. Those who are the most sedentary have a greater risk of heart and blood vessel disease, which may lead to an early death. This project will investigate the effect of sitting still for 3 hours on blood vessel health in individuals with COPD. It will also investigate whether breaking up the amount of time patients sit with regular short bouts of walking (5 minutes each hour) at a comfortable pace chosen by the patient can have a positive effect on maintaining the health of their blood vessels. It is hypothesized that blood vessel health will be worse after 3 hours of sitting compared to when the sitting is broken up by short bouts of walking.
