  1. 1. Endogenous Nitric Oxide Production and Pulmonary Blood Flow during different experimental lung conditions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; MEDICINE Surgery Anaesthetics and intensive care; MEDICIN Kirurgi Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. READ MORE

  2. 2. Non-Invasive Measures of Heart Failure

    University dissertation from Department of Clinical Physiology, Lund University

    Author : Mikael Kanski; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; diagnosis; magnetic resonance imaging; blood flow; 4D flow; pulmonary blood volume; kinetic energy;

    Abstract : Heart failure is a clinical syndrome characterized by an inability of the heart to meet the metabolic demands of the body. Approximately 1-2% of the population in the western society has the diagnosis, and the 5-year mortality rate is comparable with the common cancer diagnoses. READ MORE

  3. 3. Blood flow specific assessment of ventricular function Visualization and quantification using 4D flow CMR

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Alexandru Grigorescu Fredriksson; Carljohan Carlhäll; Bengt Johansson; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The spectrum of cardiovascular diseases is the leading cause of morbidity and mortality globally. Early assessment and treatment of these conditions, acquired as well as congenital, is therefore of paramount importance. The human heart has a great ability to adapt to various hemodynamic conditions by cardiac remodeling.

  4. 4. A minimally invasive axial blood flow pump : an experimental and clinical study

    University dissertation from Linköping : Linköpings universitet

    Author : Urban Lönn; Howard Frazier; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Axial blood flow pump; Hemopump; LVAD; Beating heart CABG; MEDICINE; MEDICIN;

    Abstract : The first aim of this thesis was to evaluate a new minimally invasive axial blood flow pump for treatment of patients needing circulatory support after open heart surgery. This system, the Hemopump temporary cardiac assist device, is a very small catheter mounted intracorporeal pump, which is introduced transvalvularly into the left ventricle. READ MORE

  5. 5. Measurement and Analysis of Intracardiac Blood Flow and Vortex Ring Formation

    University dissertation from Linköping : Linköpings universitet

    Author : Johannes Töger; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood flow; dynamical systems; magnetic resonance imaging; heart failure; vortex ring formation;

    Abstract : Increased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. READ MORE
