DataBase of pulmoNary hyPertesion in PoLish Population - BNP-PL
The BNP-PL is a multicenter, observational study in which patients are prospectively followed in order to investigate clinical course and management of pulmonary hypertension in Poland. All patients diagnosed with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension confirmed in right heart catheterization, will be eligible to participate in the study.
Determinants of Right Heart Remodeling in Patients With CTEPH or PAH
Right heart failure is the main cause of morbi-mortality in patients with pulmonary hypertension (PH), including patients of chronic thrombo-embolic pulmonary hypertension (CTEPH) or pulmonary arterial hypertension (PAH) etiologies. Endarterectomy is an effective treatment for patients with CTEPH to lower pulmonary pressure. Evidence of postoperative right heart remodeling are contrasted according to the studies and determinants of right heart failure are still unclear. Similarly, few evidence exists on right ventricular remodeling after bilateral lung transplantation for patients with pulmonary arterial hypertension (PAH). Recent...
Development of Novel Physiological CMR Methods in Health and Disease
Physiological cardiovascular stress test plays a crucial role in the assessment of patients with suspected heart disease. There are several methods of cardiac physiological stress tests and each of them offer varied insight into cardiac physiological adaptation: passive leg raise, intra-venous fluid challenge, pharmacological stressors and physical exercise stress test. Echocardiography, which is the mainstay for the non-invasive rest/stress assessment of the left ventricular (LV) haemodynamics has several limitations. Novel methods of CMR imaging allow to map intra-cardiac flow in three-dimension using novel flow acquisitions. These...
Differential Diagnosis of Pulmonary Hypertension With Automated Image Analysis
The aim of the study is to determine relevant morphologic parameters of the lung vasculature for the differentiation between different groups of patients with pulmonary hypertension (PH) by thoracic computer tomography (CT). In this pilot study patients undergoing right heart catheterization will be investigated by thoracic CT and special software to determine morphologic readouts. The investigators expect that using this non-invasive method, parameters relevant for the differentiation of the patients with PH can be determined.
DNA Methylation Dynamics Underlying Arterial Remodeling in PAH Patients: CLEOPAHTRA Clinical Trial
To identify epigenetic-sensitive modifications and novel biomarkers linked to pathogenesis of pulmonary arterial hypertension (PAH), we will perform the first study analyzing differentially-methylated regions (DMRs) in circulating T cells (CD04+ and CD08+) isolated from peripheral blood of patients undergoing right heart catheterization. Moreover, we will perform RNA deep sequencing on lung tissue biopsies to validate if DNA methylation signatures in circulating T cells could reflect perturbations of gene expression in lung tissues.
Dyspnea in Chronic Thromboembolic Pulmonary Hypertension
Pulmonary embolism, or clots blocking the blood vessels of the lungs, is a common clinical condition requiring treatment with blood thinners. In most patients, recovery is complete. A small proportion of patients, however, develop complications (high blood pressure in the lung circulation, i.e. pulmonary hypertension). Persisting breathlessness during activity is a common symptom in many of these patients and leads to a reduced ability to engage in daily physical activity. The reason for this activity-related breathlessness remains uncertain and is the main question of the proposed study. Using new sophisticated technology, the ...
Early Diagnosis of Pulmonary Hypertension in Patients With Inflammatory Rheumatic Connective Tissue Diseases
The purposes of this study are (I), to evaluate various screening methods for their ability to predict and to confirm Pulmonary Hypertension (PH) in scleroderma patients, and (II) to evaluate the incidence of PH (i.e. the number of new cases per year) in scleroderma patients.
Effect of Acetazolamide on Right Heart Function at Rest in Lowlanders With COPD Traveling to High Altitude
The purpose of this randomized, placebo-controlled double-blind trial is to evaluate the effect of acetazolamide on right heart function at rest in lowlanders with chronic obstructive pulmonary disease (COPD) traveling to high altitude (HA) and developing early signs of altitude-illness.
Effect of a Parenteral Emulsion With Omega3 on PPHN
The purpose of this study is to evaluate the effect of a parenteral emulsion containing n-3 long-chain polyunsaturated fatty acids (LC-PUFA) in fish oil on clinical outcomes, markers of inflammation and oxidative stress, and pain in neonates with persistent pulmonary hypertension of the newborn (PPHN) compared with those who receive an emulsion containing soy oil and medium-chain triglycerides (MCT) without n-3 LC-PUFA.
Effect of Exercise and Respiratory Therapy on Right Ventricular Function in Severe Pulmonary Hypertension
Chronic pulmonary hypertension (PH) is associated with impaired exercise capacity, quality of life and right ventricular function.The disease is characterized by an increase of pulmonary vascular resistance and pulmonary arterial pressure, leading to right heart insufficiency. In later stages of the disease, the right heart is not able to further increase right ventricular contractility (cardiac index) during exercise. Within the last decade, new disease-targeted medical therapies have been approved for treatment of pulmonary arterial hypertension (PAH). Sequential and upfront combinations of these agents have shown to further ...
