  1. 1. Myocardial Topical Negative Pressure

    Författare :Sandra Lindstedt Ingemansson; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary blood flow; microvascular blood flow; topical negative pressure TNP ;

    Sammanfattning : The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. LÄS MER

  3. 2. Movement artifact reduction in laser Doppler blood flowmetry : myocardial perfusion applications

    Författare :MG Daniel Karlsson; Karin Wårdell; Knut Kvernebo; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser Doppler perfusion monitoring (LDPM) and imaging (LDPI) enable assessment of tissue microvascular perfusion. The techniques are based on the Doppler broadening of the optical spectrum occurring when coherent laser light is scattered by moving red blood cells (RBC). LÄS MER

  4. 3. Physiological aspects on intracardiac blood flow

    Författare :Per Arvidsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

    Sammanfattning : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.

  5. 4. Doppler evaluation of coronary blood flow and coronary flow reserve - Clinical and experimental studies

    Författare :Gylfi Oskarsson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Pediatri; Cardiovascular system; Kardiovaskulära systemet; fetal asphyxia; transposition of the great arteries; dilated cardiomyopathy; aortic stenosis; child; neonate; adenosine; coronary flow reserve; Doppler; coronary flow;

    Sammanfattning : Heart diseases in children cause different combinations of myocardial hypertrophy, increased intra-ventricular pressures, volume overload and decreased oxygen saturation. This may affect basal coronary flow and the ability of the heart to maximally increase coronary flow. LÄS MER

  7. 5. Non-Invasive Measures of Heart Failure

    Författare :Mikael Kanski; Lund Klinisk fysiologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
