Filter by:High mortality rates due to cardiovascular disease in end-stage renal disease patients been described by epidemiological and clinical studies. It accounts for approximately 50 percent of deaths in dialysis patients. Although controversial, this may be due to the presence of excess vascular calcification particularly in the form of extensive coronary artery calcification which can be observed even in very young dialysis patients. It was suggested that abnormalities of the right ventricular function in patients with end-stage renal disease were largely due to pulmonary hypertension which usually develops secondary to pulmonary artery calcifications.
The purpose of the present pilot study is to test the hypothesis that in patients with group 1 pulmonary arterial hypertension (PAH) who are on regular oral pulmonary vasodilator therapy, inhaled albuterol causes transient pulmonary vasodilation.
The collected data from the Zurich Registry for pulmonary Hypertension (PH) are evaluated in a retrospective analysis. This study examines the number of patients and their exact diagnoses who are treated at the University Hospital of Zurich and potentially other participating in the Zurich Registry. Other demographic parameters such as age, gender and body-mass-index are also part of the evaluation. Furthermore, the analysis will focus on the newest guidelines on PH. Therefore, it will be checked how many patients would fulfill the therapeutic goals in terms of New York Heart Classification (NYHA), 6-minute walk distance, sign of right heart failure and N-terminal pro-brain-natriuretic peptide(NTproBNP). Additionally, the study examines on how the patients are treated. Despite the different kind of Drugs, the focus lies on the combination therapy (single, double, triple) and the impact the therapy had on the patients.
Pulmonary Hypertension (PH) is a severe disease with a bad prognosis. However, thanks to extensive research in this field, there are more and better treatment options that allow patients to participate in recreational activities at moderate altitude or bring up the question of air-travel. Still very few is known about the effects hypoxic conditions have on PH patients. The aim of this study is to investigate the effects of hypoxia in comparison to normoxia and hyperoxia on pulmonary hemodynamics in patients with pulmonary hypertension during routine right heart catheterisation. We aim to get insight into the pathophysiology of pulmonary hemodynamics under hypoxic conditions in comparison to normoxia and hyperoxia in patients with pulmonary arterial and chronic thromboembolic pulmonary hypertension compared with control patients, that are scheduled for right heart catheterisation due to dyspnea but have no PH.
The primary goal of this study is to determine the feasibility and acceptability of a 6-week multicomponent integrative therapy program, Urban Zen Integrative Therapy (UZIT), for adults with chronic, life-limiting cardiopulmonary disease. The secondary goal is to determine preliminary efficacy of UZIT in symptom management. Pulmonary hypertension (PH) presents an excellent model of a severe, life-limiting cardiopulmonary condition with high symptom burden and poor outcomes suitable for this scientific inquiry. Despite medical and pharmacological advances in the treatment, 50-55% of persons with PH will die within three years after diagnosis. Medical management often involves life-long complex pharmacological treatment requiring high levels of skill, knowledge, and social support. Clusters of bothersome symptoms such as chest pain, anxiety, insomnia, dyspnea, and fatigue can overwhelm patients' ability to manage daily activities and medication treatment regimens. Side effects of treatment induce additional noxious symptoms. The high prevalence of physical symptoms, depression, and anxiety among adults with PH confirmed in our prior work, can also lead to reduced (HRQoL). A literature search found no published report of complementary, integrative therapy interventions to alleviate symptoms in adults with PH. This study will use a single group repeated-measures design to address the feasibility and acceptability of the intervention and to explore preliminary efficacy.
Mitral regurgitation (MR) is a prevalent valvular heart pathology. Indications for surgery include symptoms, impaired left ventricular function or enlarging dimensions, new onset atrial fibrillation, pulmonary hypertension, asymptomatic status with a high likelihood of success. Asymptomatic severe primary MR can be initially monitored without impairing long term survival. However, significant symptoms or impairment of left ventricular function is associated with worse prognosis due to long term heart failure. Some physicians wait for early symptoms before referring for surgery and this is reflected by a great variation in referral patterns, but symptomatic status is subjective and difficult to assess. Nearly all of the surgical indications are based on expert opinion rather than significant evidence base. The primary aim of this project is to improve the current guidelines for surgery for primary MR by finding an objective marker of functional capacity which correlates with surrogates of prognosis and detects early decline, but returns to normal after surgery.
The purpose of this study is the evaluation of cardiac and pulmonary response to cardiopulmonary exercise in severe mitral regurgitation and its variation under treatment (surgical mitral valve repair, percutaneous mitral valve repair, optimal medical treatment). The study is conducted as a prospective, observational, single-center study. Patients suffering from symptomatic severe mitral regurgitation will be eligible, if they are referred to the University Hospital of Regensburg, Germany, for further diagnostic procedures and heart team discussion. Cardiopulmonary exercise testing is performed comprising standardized stress echocardiography as well as ergospirometry. Additional detailed assessment will be conducted including standardized questionary, clinical examination, transesophageal echocardiography and measurement of biomarkers.
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 current data on the incidence of pulmonary hypertension (PH) are very variable, depending on the different studies designs. There are no data on the prognostic of PH in patients with asymptomatic pulmonary thromboembolisms (PT), neither paucisymptomatic PH, in which without a prospective follow-up would be underdiagnosed. We thought that the prognosis of both clinical forms (PT with or without symptoms) would be similar. The objective of this study is know the real incidence of pulmonary hypertension (PH) post symptomatic and asymptomatic pulmonary thromboembolic (PT).
