2. 1. Pulmonary hypertension. Clinical and pathophysiological studies

   Author : Nedim Selimovic; Göteborgs universitet; []
   Keywords : Pulmonary hypertension; Echocardiography; Right heart catheterisation; Pulmonary vascular resistance; Pulmonary function tests; Lung transplantation; Mortality on the waiting list; Vascular remodelling; Growth substances; Inflammation; Endothelin;

   Abstract : Pulmonary hypertension (PH) is a common abnormality, most often associated with various cardiopulmonary diseases. Pulmonary arterial hypertension (PAH) is a devastating pulmonary vascular disease characterised by the proliferation of endothelial, smooth-muscle cells and fibroblasts. READ MORE

4. 2. Vascular remodeling in pulmonary hypertension

   Author : Ya-Ting Chang; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Pulmonary hypertension (PH) is a progressive obliterative vasculopathy with multifactorial etiology and high mortality rate. Endothelial dysfunction, excessive vascular remodeling, inflammation and in situ thrombosis contribute to increased vascular resistance and gradual occlusion of pulmonary vessels. READ MORE

5. 3. The bone cement implantation syndrome - epidemiology, pathophysiology and prevention

   Author : Mathias Hård af Segerstad; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone cement implantation syndrome; femoral neck fracture; cemented hip hemiarthroplasty; pulmonary haemodynamic; right ventricle ejection fraction; pulmonary vascular resistance; hemiarthroplasty;

   Abstract : Bone cementation implantation syndrome (BCIS) has significant morbidity and mortality for patients who are undergoing cemented hip hemiarthroplasty or arthroplasty. The aim of this thesis is to contribute with information of the epidemiological parameters of BCIS and identify risk factors. READ MORE

6. 4. Vardenafil and methylarginines in pulmonary hypertension

   Author : Anna Sandqvist; Gerhard Wikström; Jörn Schneede; Amrita Ahluwalia; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vardenafil; pulmonary hypertension; pharmacokinetics; haemodynamics; right heart catheterization; adenosine; dimethylarginines; phosphodiesterase type 5 inhibitors; endothelin receptor antagonists; klinisk farmakologi; Clinical Pharmacology;

   Abstract : Background: Pulmonary hypertension (PH) is a rare condition characterized by endothelial dysfunction and vascular remodelling, leading to increased pulmonary vascular resistance (PVR) and right ventricular heart failure. Endothelial dysfunction is associated with an imbalance between vasoconstrictor compounds, such as endothelin and thromboxane A2, and vasodilator compounds, such as prostacyclin and nitric oxide (NO).

7. 5. Pulmonary Hypertension and the Nitric Oxide System

   Author : Dan Henrohn; Gerhard Wikström; Ulla Lindqvist; John Pernow; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pulmonary hypertension; nitric oxide; ADMA; arginine; nitrate; nitrite; vardenafil; beetroot juice; Medicinsk vetenskap; Medical Science;

   Abstract : Pulmonary hypertension (PH) is a pathophysiological state associated with several medical conditions, leading to progressive rise in pulmonary vascular resistance (PVR) and right ventricular failure. The clinical PH classification encompasses five main World Health Organization (WHO) groups; pulmonary arterial hypertension (PAH), PH due to left heart disease, PH due to lung diseases and/or hypoxia, chronic thromboembolic PH, and PH with unclear multifactorial mechanisms.
