Hypertension Paid Clinical Trials in Maryland

It is unknown if obesity contributes to the development of heart disease in African American men and women. This study was created to determine whether there is a relationship between sex and body size and the incidence of heart disease in African American men and women. Researchers will attempt to associate obesity with the presence of heart disease risk factors. Risk factors that will be studied include; total body fat, body fat distribution, fat content of the blood (triglyceride concentration, low density lipoproteins \[LDL\], and high density lipoproteins \[HDL\]), how fast fat is removed from the blood, and how well insulin works in the body. Scientific studies have shown that obesity and increased levels of fat content in the blood are important risk factors for heart disease in Caucasian women. However, similar studies in African American women have failed to show the same correlation. In fact, it appears that African American women in all three body weight groupings, nonobese, overweight, and obese experience high death rates due to heart disease. In addition, prior research has shown that obese African American men tend to have elevated levels of fat in the blood while African American women have normal blood fat levels. Therefore, if high levels of triglycerides (fat found in the blood) are not seen in non-diabetic obese African American women, it cannot be considered a risk factor in this population. This suggests that studies conducted on Caucasian women may not provide insight into heart disease risk factors in African American women. The study will take 2000 healthy non-diabetic African American men and women (ages 18-70) and body mass index 3 subgroups; nonobese, overweight and obese. Diabetes undeniably increases the risk of heart disease. Therefore patients suffering from diabetes will not be included in the study. Candidates for the study will undergo a series of tests and examinations over 2 outpatient visits. Subjects will have body fat analyses, resting energy expenditure measurements, an EKG (electrocardiogram), and specific blood tests. Researchers believe this study will provide significant insight into the causes of obesity and heart disease in African Americans. Read Less

Background: - High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. Some people have disease-associated PAH and some have PAH from an unknown cause. Researchers want to follow the natural history of all PAH patients to understand how PAH progresses in order to discover targets for future research into new treatments. To further identify treatment targets, they will compare healthy volunteers to patients with PAH. Objectives: - To study the natural history of PAH. Eligibility: * Individuals at least 18 years of age who have PAH. * Healthy volunteers at least 18 years of age. Design: * Participants with PAH will have periodic visits to the National Institutes of Health Clinical Center. After the first visit, they will return in 6 months and then yearly or every other year for as long as the study continues. * The first visit will take up to 3 days. It will involve the following tests: * Physical exam and medical history * Blood and urine samples * Heart and lung function tests and imaging studies * Six-minute walk test * Questions about exercise and physical activity * Healthy volunteers will have only one visit to the Clinical Center, during which they will undergo screening tests, and complete many of the same tests as patients with PAH Read Less

This is a non-interventional study to assess the prevalence of endogenous hypercortisolism (eHC) in patients with resistant hypertension (rHTN) and will enroll approximately 1000 patients at approximately 45 sites in the United States (US). Each patient will have an initial visit for screening. After eligibility is confirmed, a limited exam will be performed and demographic and medical history will be collected. A second visit will be a fasting blood draw at 8 AM after taking 1 mg of dexamethasone the night before at 11 PM. Cortisol level and all other study labs will be included, and a urine test will be done. After the lab results are obtained, a third visit will be scheduled only for patients with eHC and will include a non-fasting blood draw at 8 AM and scheduling of a non-contrast CT scan. Read Less

The GZPL master protocol will support 2 independent studies, J2A-MC-GZL1 (GZL1) and J2A-MC-GZL2 (GZL2). The purpose of this study is to create a framework to evaluate the safety and efficacy of orforglipron for the treatment of hypertension in participants with obesity or overweight. Read Less

Background: The adrenal gland makes the hormone aldosterone. This helps regulate blood pressure. An adrenal gland tumor that makes too much aldosterone can cause high blood pressure and low potassium. The cause of these tumors is unknown, but sometimes they are inherited. Objective: To study the genes that may cause primary aldosteronism in Black individuals. Eligibility: People ages 18-70 who: Are Black, African American, or of Caribbean descent And have difficult to control blood pressure or primary aldosteronism Relatives of people with primary aldosteronism Design: Participants who are relatives of people with primary aldosteronism will have only 1 visit, with medical history and blood tests. Participants with primary aldosteronism or difficult to control blood pressure (suspected to possibly have primary aldosteronism) will be screened with a 1-2 hour visit. If they qualify, they will return for a hospital stay for 7-10 days. Tests may include: Medical history Physical exam Blood tests: Participants will have a small tube (IV catheter) inserted in a vein in the arm. They may drink a glucose-containing liquid or get a salt solution. If medically indicated, they may have invasive blood tests with a separate consent. Urine tests: Some require a high-salt diet for 3 days. Heart tests Scans: Participants lie in a machine that takes pictures of the body. A dye may be injected through a vein. Small hair sample taken from near the scalp. Kidney ultrasound Bone density scan: Participants lie on a table while a camera passes over the body. If the doctors feel it is medically necessary, they will offer participants treatment depending on their results. These treatments may cure the patient of their disease and may include: 1. Having one adrenal gland removed by the Endocrine surgeon under anesthesia. Patients will have follow-up visits 2-4 weeks after surgery. 2. Taking drugs to block the effects of aldosterone Participants may return about 1 year later to repeat testing.... Read Less

Background: Childhood-onset essential hypertension (COEH) is high blood pressure that develops in children and teens. High blood pressure is a major risk factor for heart disease. COEH is more likely to be caused by changes in genes rather than by factors like stress or diet. Researchers want to learn more about how changes in genes relate to COEH. They hope to use that information to develop better treatments for children with high blood pressure. Objective: This natural history study will look for genes and gene changes that may lead to COEH. Eligibility: People aged 2 years and older with COEH or who had COEH when they were children. Healthy relatives of those with COEH are also needed. Design: Participants will have one clinic visit per year for up to 10 years. All participants will have a physical exam. They will provide samples of blood and urine. At their first visit, they will have a swab (like a Q-tip) rubbed between their gums and cheeks. They may agree to having a skin biopsy; a piece of skin about the size of a pencil eraser will be removed. Affected participants aged 2 to 17 years old will have additional tests: * They will have sensors placed on their skin to look at their blood vessels and see how blood is moving in their bodies. * They will lie or stand while a machine measures the amount of fat and muscle in their bodies. * They will have an ultrasound; a wand will be rubbed against their skin to take pictures of their kidneys. Other things are optional for all participants: * They may have photographs taken of their bodies. * They may have tests of their heart function. * They may have different types of imaging scans.
