Active clinical trials for "Hypertension"

Blood pressure measurements by three methods Office Blood Pressure Measurement (OBPM), Automated Office Blood Pressure Measurement (AOBPM), and Home Blood Pressure Measurement (HBPM) were collected retrospectively across three visits for patients (N=28) referred to a specialty hypertension (HTN) clinic. Demographic data were analyzed using summary statistics. The differences between AOBPM, HBPM, and OBPM were examined using mixed models repeated measures analysis for time and method for each visit.

The impact of a sojourn at 2500 m of high altitude for 26-30 h on constant work-rate exercise test time in patients with precapillary pulmonary hypertension

The impact of hypoxia at 2500m of high altitude on sleep in patients with precapillary pulmonary hypertension

The impact of hypoxia on maximal work rate during incremental ramp exercise within 3-6 hours after arriving at 2500m of high altitude in patients with precapillary pulmonary hypertension

Inspiratory muscle training for 8 weeks in patients with chronic thromboembolic pulmonary hypertension.

Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are serious diseases with poor prognosis despite recent advances. Currently, pulmonary hypertension (PH) is considered a cell proliferative disorder, which has not been adequately characterized due to the lack of markers. A better understanding of the mechanisms that regulate this proliferative disorder will allow the identification of new therapeutic targets for HP. The objective of the project is to identify cell proliferative processes in severe forms of PH. Patients with PAH (n=20), CTEPH (n=20) and healthy controls (n=20) will undergo characterization of microRNAs (miRNAs) contained within circulating microparticles (MPs) analysis and mitochondrial functionality and FDG-PET to compare cell metabolism in the lungs and the right ventricle between patients and controls.

Aim of the study is to evaluate the role of chemoreceptor activity and ventilation perfusion mismatch on the genesis of exercise induced hyperventilation in Pulmonary hypertension patients. So the investigators tested the chemoreceptor response at rest, both with hypoxic and hypercapnic stimuli, and the ventilatory response during exercise analyzing its two components, alveolar and dead space ventilation.

Pulmonary hypertension (PH) is defined as a pulmonary arterial mean pressure (meanPAP) ≥ 25 mmHg in the right heart catheterization. There are different forms of PH defined in the classification of Dana Point 2008. PH is diagnosed with right heart catheterization but there are other non invasive methods which can be used for screening like echocardiography, stress echocardiography and cardio pulmonary exercise testing. For prognosis of PH patients the limitation of the pulmonary circulation is very important. Therefore the cardiac index (CI) is a good parameter for the right ventricular function. The gold standard for CI measures is the thermodilution, an invasive method performed during right heart catheterization.

The primary objective of this study is to test the hypothesis that twice overnight high-dose rosuvastatin loading before RNA followed by 3-month treatment with regular doses of rosuvastatin can reduce both the acute and late renal artery damage.
