Filter by:1. Aim: The aim of the clinical trial is to study the accuracy of the TensorTip device compared with registered (FDA-approved) invasive and non-invasive devices. 2. Hypothesis: Human physiological biomarkers may be measured from the color distribution of the internal or external (skin) tissue. The technology of the TensorTip finger-mounted device is based on the color distribution of the peripheral blood tissue, which enables the measurement of certain biomarkers and vital signs under consideration.
The purpose of this study is to determine whether add-on of intensive vasodilator therapy can improve the coronary perfusion and reduce the total peripheral resistance in patients with ongoing treatment for essential hypertension.
The overall aim of Healthy Bodies, Healthy Hearts research study is to promote physical activity in women aged 45-65 years to promote reduced risk of cardiovascular disease. The investigators are conducting an intervention for 12 weeks that promotes physical activity through support groups, group exercise sessions or through information that is given at the baseline appointment. Participants will be randomly assigned to a group.
The purpose of the study was to assess efficacy and safety of fixed dose combination of 5 mg amlodipine/80 mg valsartan compared to 160 mg valsartan monotherapy in lowering blood pressure in Taiwanese patients.
This is an open-label, not controlled, sequential, dose escalation study of 16 weeks' duration. The study is composed of two periods: a 0-2 week optional wash-out period depending on previous antihypertensive treatment(s), followed by a 16-week open-label active treatment period. Patients will be evaluated every 4 weeks during period 2. Treatment will start with Aliskiren 150 mg with dose titration to Aliskiren 300 mg, and addition of HCTZ 12,5 mg and 25 if control of BP is not achieved (< 140/90 mmHg or 130/ 80 mmHg in diabetics patients). All patients who have reached their BP target will be considered as having met the primary endpoint and this visit will be considered as the final visit.
High blood pressure (hypertension) is called the "silent killer" because many people do not know they have it, and do not know when it is well controlled. Unfortunately, over time uncontrolled hypertension can cause irreversible organ damage that can lead to heart attack, stroke, heart failure, and kidney failure. If a person cannot control their blood pressure with diet and exercise, doctors often prescribe medications to help control the blood pressure. Nebivolol is a medication that has been recently approved by the FDA for the treatment of hypertension. Our study will investigate whether treatment with nebivolol, as compared to another medication called metoprolol, in African Americans with hypertension will be more effective in protecting blood vessels against the harmful effects of high blood pressure. Over time high blood pressure causes hardening of the arteries (atherosclerosis) which leads to narrowing of the blood vessels and reduces blood flow to our organs. Arteries also relax and contract naturally, which further changes the blood supply. When arteries are narrowed, exercise can bring on a condition in which the blood supply is inadequate, and this might result in the sensation of pain. Cells lining our blood vessels produce a variety of substances that normally cause arteries to relax. Two of these substances are called nitric oxide (NO) and endothelium-derived hyperpolarizing factor (EDHF). We are trying to determine the nature of these substances in African Americans with high blood pressure and how it is affected by nebivolol and metoprolol. One way to determine this is to inject drugs such as L-NMMA (N(G)-monomethyl-L-arginine) or TEA (tetraethylammonium chloride), which block the production of NO and EDHF respectively, and then study what happens to the blood flow at rest and during exercise. It is our thought that nebivolol, in comparison to metoprolol, will increase the substances that naturally cause arteries to relax and improve blood supply.
The purpose of this study is to compare the effects of 24 weeks of either a blood pressure education and walking program versus a yoga exercise program versus the combined intervention of blood pressure education and yoga on reducing mild to moderate high blood pressure in pre-hypertension and stage 1 hypertension subjects.
The purpose of this study is to demonstrate the relative bioavailability of Nadolol (1 x 80 mg) tablets under fasting conditions.
This study will investigate whether retaining potassium in the body will lead to changes in blood pressure and changes in blood and urine samples.
This study is an open randomized controlled trial of 12-month duration, which compares the use of a home blood pressure (BP) tele-management system to the usual approach of home BP monitoring in older diabetic patients with uncontrolled systolic hypertension. The purpose of this study is to determine whether home blood pressure tele-management system will markedly improve blood pressure control in a primary care setting.
