Active clinical trials for "Hypertension"

This is a randomized, double-blind, placebo-controlled, multicenter, multinational study investigating the effect of riociguat (MK-4836) in patients with early pulmonary vascular disease.

The purpose of this study is to explore the efficacy and safety of LTP001 in participants with pulmonary arterial hypertension (PAH) to determine if LTP001 has an adequate clinical profile to warrant further clinical development in this indication.

This is a randomized, controlled, pragmatic trial designed as a "type I hybrid effectiveness-implementation trial" that tests a hypertension program integrating a virtual Collaborative Care Clinic (vCCC), home blood pressure monitoring, and telehealth for lowering blood pressure (BP) in two health systems.

The main objective of the study is to assess the effect of treprostinil palmitil inhalation powder (TPIP) compared with placebo on pulmonary vascular resistance.

The proposed study will assess the effects of yoga postures and slow, deep breathing in altering oxidative stress, vascular function, and blood pressure.

This study is open to adults with liver cirrhosis and high blood pressure in the portal vein (main vessel going to the liver). The purpose of this study is to find out whether a medicine called BI 685509 helps people with this condition. Participants are put into 3 groups randomly, which means by chance. Participants in 2 groups take different doses of BI 685509 as tablets twice a day. Participants in the placebo group take placebo as tablets twice a day. Placebo tablets look like BI 685509 tablets but do not contain any medicine. Participants are in the study for about 8 months. During this time, they visit the study site about 14 times. At 3 of the visits, the doctors check the pressure in a liver vein. This is done with a catheter (a long thin tube) and gives information about the pressure in the portal vein. The change in blood pressure is then compared between the groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

High blood pressure is the leading cause of cardiovascular disease worldwide. Many medicines are available to lower blood pressures successfully, as well as many non-medical options, such as dietary changes. Some effective dietary changes include decreasing sodium and increasing potassium in the diet. A lot of focus has been on sodium intake yet; potassium intake in the diet remains low amongst adult Canadians. Excellent data exist in the published research reporting that increasing potassium intake, either as diet or even as supplements, reduces blood pressure and reduces risk of cardiovascular outcomes such as stroke. The overall purpose of this study is to reveal the most effective way of increasing potassium, amongst participants with high blood pressure whose existing intake of potassium is low. In the first stage, participants with high blood pressure and proven low potassium intake will receive dietary counselling. If after 4 weeks, there has not been a desired increase in potassium intake, the patients will be prescribed an additional potassium supplement.

Background: - High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. In spite of recent advances in treatment, the death rate remains unacceptably high. Lung blood vessel function can be harmed by progressive injuries, such as inflammation, leading to worsening of the disease. A drug called spironolactone has been known to improve blood vessel function and reduce inflammation. Some people with PAH take spironolactone to help treat fluid retention. However, its effect on inflammation and blood vessel function in patients withPAH is not known. Researchers want to see if spironolactone can help these conditions in people with PAH. Objectives: - To test the effectiveness of spironolactone in treating pulmonary arterial hypertension. Eligibility: - Individuals at least 18 years of age with pulmonary arterial hypertension. Design: This study will last for 24 weeks. Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Participants will take either spironolactone or a placebo. They will take their study drug or placebo for 7 weeks. Treatment will be monitored with regular blood tests. In Week 8, participants who have had no reaction to the treatment will receive a higher dose of the drug or placebo. In Week 12, participants will have a study visit with heart and lung function tests. They will also have a 6-minute walk test, and provide blood and urine samples. After additional study visits for blood samples, participants will have a final visit in Week 24. The tests from Week 12 will be repeated at this visit.

This study compares L-arginine Versus Sildenafil as treatment for pulmonary hypertension in Children with Beta Thalassemia

Patients with autonomic failure are characterized by disabling orthostatic hypotension (low blood pressure on standing), and at least half of them also have high blood pressure while lying down (supine hypertension). Exposure to heat, such as in hot environments, often worsens their orthostatic hypotension. The causes of this are not fully understood. The purpose of this study is to evaluate whether applying local heat over the abdomen of patients with autonomic failure and supine hypertension during the night would decrease their nocturnal high blood pressure while lying down. This will help us better understand the mechanisms underlying this phenomenon, and may be of use in the treatment of supine hypertension.
