Active clinical trials for "Hypertension"

Assessment of the prognostic value of the estimation of plasma volume or its variation in patients with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) after acute right heart failure.

Patients with pulmonary hypertension underwent (routine) Holter ECG and were screened for (malignant) arrhyhtmias. Results of Holter ECGs were correlated with clinicial and technical data (echocardiography and right heart catheterization).

The six minutes stepper test (6MST) was used assess exercise capacity of individuals having different chronic conditions. In the literature, there are some validation studies analyzing validity of 6MST. In this study, the main aim was to analyse validation of 6MST in hypertensive individuals.

This is an observational clinical study, patients with systemic diseases will be enrolled according to the inclusion and exclusion criteria. Patients will received the examination of sublingual microcirculation by using incident dark field video microscope (Cytocam，Braedius Battery Powered Transilluminator). The microcirculation data includes total small vessel density, perfused small vessel density, microvascular flow index, and heterogeneity index. The patients will be divided into right groups according to their systemic diseases as follows: group 1 hypertension (60 patients), group 2 diabetes mellitus (60), group 3 hypertension and diabetes mellitus (60), group 4 end stage renal disease with hemodialysis (60), group 5 kidney transplant recipients (60), group 6 coronary artery disease (60), and group 7 peripheral arterial occlusive disease (60).

The investigators will investigate the interrelationship of macrophage migration inhibitory factor (MIF) and free T4 in patients with PAH.

The purpose of the current study is to evaluate the clinical and physiologic course of Kyrgyz highlanders with high altitude pulmonary hypertension (HAPH) by performing a longitudinal cohort study. To this end, the investigators will invite the same highlanders who participated in the study in 2012 to undergo follow-up examinations in 2017, in order to allow comparisons of current results with baseline data from 2012.

The objective of the Cloud DX Pulsewave Health Monitor study is to prospectively calibrate and validate a novel, non-invasive wrist cuff blood pressure device against the gold standard for hemodynamic monitoring (intra-arterial pressure) in voluntarily consented patient participants who are scheduled for an elective cardiac catheterization procedure for clinically valid reasons.

the investigators explore the possible role of DMSA to detect renal affection in diabetic &/or hypertensive patients by detecting difference in counts using Tc 99m DMSA in control & diabetic &/or hypertensive patients.

Pulmonary Hypertension (PH) is a hemodynamic and physiopathological condition that is defined as an increase in mean pulmonary artery pressure ≥25 mmHg when measured at rest. PH often progresses to heart failure and premature deaths. PH is a progressive disease that has many causes, which can affect people of all ages, is characterized by shortness of breath, reduced exercise tolerance, psychological distress and tiredness and reduced quality of life. Surveys of SF-36, 'Nottingham Health Profiles' and 'Minnesota Life with Heart Failure' surveys are routinely performed in PH clinically. However, none of the questionnaires are specific to pulmonary hypertension, so they are incomplete in determining the condition of the disease and the patients. There is no Turkish questionnaire for patients with pulmonary hypertension and other surveys used are inadequate in determining the condition of the patient and the patient since they are not specific to the disease. The aim is to provide a Turkish questionnaire that is specific to pulmonary hypertension in the literature.

This study evaluates RAS peptides profiles in patients with treatment resistant arterial hypertension.
