Active clinical trials for "Hypertension, Pulmonary"

The aim of the present prospective study was to evaluate dynamic changes in both pulmonary artery pressure and ductus arteriosus during the first 72 hours after birth.

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 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.

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.

The purpose of this study is to determine the prevalence of pulmonary hypertension (PH) among patients suffering from Chronic Obstructive Pulmonary Disease (COPD) and to assess the quality of life in those patients with concomitant PH compared to COPD patients without PH and those only suffering from pulmonary arterial hypertension (PAH) respectively.

Evaluate the correlation between activity level (monitored by Fitbit Flex remote activity tracker) and 6-minute walk distance (6MWD) (performed by investigator) in patients with Pulmonary Arterial Hypertension (PAH) or Chronic Thromboembolic Pulmonary Hypertension (CTEPH) over 6 months in routine clinical practice settings.

Pulmonary hypertension (PH) is a progressive disease with high mortality rate, but due to the development of drugs, the prognosis of the disease has improved. However patients still have poor exercise capacity and decrease of the quality of life. Past studies have shown that idiopathic and secondary PH are different in etiology and prognosis. It is necessary to further understand the difference between exercise capacity and quality of life of these two types of patients.

This pilot, non-interventional, company-sponsored, multi-center study documents observational data on patients under routine treatment of Pulmonary Arterial Hypertension (PAH) with inhaled iloprost (using I-Neb device for the inhalation). The planned study recruitment time is 18 months. The maximum follow up period in this study will be 12 months. The data will be collected from patients who have initiated the treatment mentioned above (inhaled iloprost using I-Neb device) since February 1st, 2013. Frequency of visits and procedures will be performed under routine conditions. The primary objective of this study is to assess the compliance of patients with WHO/NYHA (World Health Organization/New York Heart Association) functional Class III Pulmonary Arterial Hypertension treated with Inhaled Iloprost in clinical practice, using the I-neb Insight tool.
