Active clinical trials for "Hypertension"

Genetic studies of hypertension, focusing on renin-angiotensin system genes and other interacting genes

To evaluate the entire course of exercise during CPET in COPD patients. To study whether CPET, PFTs and arterial blood gases could discriminate between COPD patients with and without PH. To study whether the existence of pulmonary hypertension in COPD is related to characteristic findings in gas exchange and circulatory parameters during cardiopulmonary exercise testing (CPET).

To define the cytokine and cellular immune signature of primary hypertension. Cross sectional clinical/laboratory study.

The study addresses epidemiology of cardiovascular risk factors and major cardiovascular diseases in Russian Federation (urban and rural population). 12 regions of 1600 participants in each will be included.

Impaired myocardial deformation may determine cardiac diastolic dysfunction. The investigators will investigate the vascular determinants of myocardial deformation and twisting-untwisting and their interrelation with exercise capacity in patients with untreated arterial hypertension

The objective of this study is to know prevalence of clinical or subclinical target organ damages in Korea hypertensives by constructing nationwide hypertension registry. We will register 5000 consecutive patients with incident hypertension at 20 major university hospitals in South Korea. We will investigate clinical/subclinical target organ damages, renin/aldosterone level and cardiovascular events in each patient.

Association of maternal uric acid with maternal condition and fetal outcome in pregnant women with hypertension.

This study is a case controlled study comparing mental health status and some psychological impacts between two groups of patients first group is pregnant women without any other medical disorder during pregnancy,the second group is pregnant women complaining of hypertension with pregnancy.

There will be assessment of patients after acute pulmonary embolism for the development of CTEPH

Nocturnal hypertension (i.e. blood pressure values >120/70 or 10% higher than diurnal values, as measured by ambulatory blood pressure monitoring, ABPM) is particularly frequent in renal transplant recipients (RTR), despite the use of antihypertensive drugs. Since RTR are also affected by several sleep disorders (like insomnia, restless legs syndrome, sleep apnoea) that frankly impair their quality of sleep (SQ), the aim of the present study is to ascertain whether a relationship exists between nocturnal hypertension and SQ. In fact, both nocturnal hypertension and sleep disorders may favour the onset or the progression of cardiovascular diseases, the first cause of death in RTR.
