2. 1. Variability of blood pressure and heart rate in borderline and mild hypertension : With special reference to spectral analysis

   Author : Reijo Takalo; Uppsala universitet; []
   Keywords : Medical sciences; hypertension; blood pressure; ambulatory monitoring; power spectrum analysis; pulsecontour method; systemic hemodynamics; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

   Abstract : The aim of this thesis was to study whether blood pressure (BP) or heart rate (HR) variability in borderline (BHT) and hypertensive (HT) subjects differs from that in normotensive (NT) subjects, and whether indices for BP and HR variability can be used in risk stratification for future hypertension. The study groups consisted of 35 NT, 29 BHT, and 34 HT middle-aged men. READ MORE

4. 2. Vardenafil and methylarginines in pulmonary hypertension

   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).

5. 3. Skin fibrosis, internal organ involvement and auto antibodies in systemic sclerosis: longitudinal development and impact on survival

   Author : Roger Hesselstrand; Reumatologi och molekylär skelettbiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; Skeleton; proteoglycan; pulmonary hypertension; organ involvement; auto antibodies; survival; systemic sclerosis; prognosis;

   Abstract : Systemic sclerosis (SSc) is a connective tissue disease with a highly variable prognosis. Since new treatment strategies are emerging, there is a need for prognostic markers in order to help allocate patients to the optimal treatment. READ MORE

6. 4. In the hands of ohm : hemodynamic aspects in pulmonary hypertension

   Author : Erik Tossavainen; Per Lindqvist; Michael Henein; Stefan Söderberg; Peter Eriksson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kardiologi; Cardiology;

   Abstract : Congestive heart failure (CHF) is one of the most challenging diseases in terms of health care demand and mortality, in the western world. Despite major breakthroughs in the fields of diagnosis and treatment over the three last decades, the management of CHF still remains challenging. READ MORE

7. 5. Transjugular intrahepatic portosystemic shunt in the treatment of symptomatic portal hypertension

   Author : Kerstin Rosenqvist; Rickard Nyman; Charlotte Ebeling Barbier; Fredrik Rorsman; Lars-Gunnar Eriksson; Lars Lönn; Uppsala universitet; []

   Abstract : Portal hypertension (PHT) is a condition with serious complications, such as variceal bleeding, refractory ascites and bowel ischemia. The cause of PHT may be pre-, intra- or post-hepatic. Initial treatment is pressure-reducing drugs and the treatment of acute symptoms. READ MORE
