The purpose of this research study is to understand the association between heart and brain health in a population of 40-75 year olds. In this study, we will work to better understand blood vessel stiffness and brain function in African American and non-Hispanic white individuals. You will be asked to give blood during the study visit. Additional information will be obtained to help the researcher better understand the blood vessel and brain function data collected. There is only one study visit that last roughly 2 hours and compensation will be available.
The purpose of this study is to collect measurements related to the body such as blood pressure, the amount of oxygen in the blood, and heart rhythm recordings. Findings from this study may be used to help design new device-based monitoring technologies in the future.
Continuous blood pressure readings will be obtained during standard of care heart catheterization procedures that include the use of an arterial blood pressure line. Continuous readings of oxygen saturation and ECG will also be obtained. Participants will consist of subjects aged ? 18 years who are scheduled to undergo a cath-lab (cath-lab, percutaneous coronary intervention or equivalent) procedure that includes the use of an arterial blood pressure line.
Pre-eclampsia (PE) happens in pregnancy. It features new onset high blood pressure. It is a major cause of problems to the mother and unborn child. It can lead to health problems in mother and child in the future, which causes a public health problem. We do not know everything about it, but we think it starts in the placenta (the organ that nourishes the unborn child). At this time, we do not know who will get PE. We want to study the placenta, to learn more about the disease.
HIV testing is often shunned in community settings due to the stigma of HIV-centric services. Our recent pilot study strongly suggest that integration of a package of screening that include HIV, diabetes, and hypertension hold promise of substantially increasing the uptake of HIV testing while simultaneously providing direly needed community screening for non-communicable disease (NCDs) like diabetes and hypertension, which themselves are at epidemic levels in Sub-Saharan Africa. This study will examine whether integrating HIV screening with NCD screening will improve uptake of HIV testing and whether integrating HIV and NCD care will improve retention.
This is a clinical study looking at the effectiveness and safety of a new device call The Paradise System to use for renal denervation in patients who have mild to resistant hypertension. The study is divided into two groups, those on one to two anti hypertensive medications and those on three or more. For those only taking one or two medications, they will stop their current blood pressure medication while monitoring their blood pressure. Those who are taking 3 or more blood pressure medications will stop their current medication regime and be given one of two combination medications while monitoring their blood pressure. In each of the groups have the patients, if and when they continue to meet study inclusion criteria, will be randomized to undergo a renal denervation procedure using the new system vs no procedure. Their assignment will not be made known to them. All groups will be follow up to 3 years but for patients who did not initially have the procedure will be allowed to do so after one year. The goal of the renal denervation is to lower blood pressure by using ultrasound waves to heat and disable the nerves surrounding the blood vessels leading to the kidneys. It is believed these nerves may be too active in patients with high blood pressure.
This research study is for children between 6 years and 18 years of age who have been diagnosed with hypertension, or high blood pressure. Hypertension or high blood pressure is when someone's blood vessels, called arteries, tighten too much. The study lasts 12 months and could involve up to 17 study visits. Compensation is available.
The main purpose of this study is to find out if the study drug, Azilsartan medoxomil (also called AZM, TAK-491, or AR14) is effective in controlling blood pressure in children 6 to less than 18 years of age and to find out if it is safe and well tolerated in this age group compared to placebo. The safety and effectiveness of AZM in children less than 18 years of age have not yet been established and currently are under investigation in the age group 1 to 17 years. This means it does not currently have FDA approval for use in children and adolescents.
Another purpose of the study is to compare a drug called losartan potassium (Cozaar) to AZM. Cozaar is an FDA approved drug that is used to treat high blood pressure in adults and children
This study will examine the influence of smart phone technology enabled breathing awareness meditation on BP control at rest & in the natural environment. Psychological & physiological mechanisms will be examined in efforts to better understand underlying mechanistic pathways linking meditation with improved BP. Subjects will be prehypertensive adults (SBP 120-139mmHg on 3 occasions). Anthropometric, neurohormonal, psychological & CV phenotypes will be evaluated on 5 occasions: baseline, months 1, 3, 6, and 12.
