  1. 1. Influencing factors of delayed medical treatment in patients with acute myocardial infarction : A descriptive review

    University essay from Högskolan i Gävle/Avdelningen för vårdvetenskap

    Author : Ma Jieyu; Lin Huixian; [2022]
    Keywords : ;

    Abstract : Background: A 2017 study estimated that more than 800,000 people suffer from acute myocardial infarction each year, and in most cases, 27% of patients die from it before they reach the hospital. Pre-hospital delays have been relatively stable over the past two decades, and have not improved significantly in any of those two decades. READ MORE

  2. 2. Förändringar i vilo-EKG hos hästar med dynamiska obstruktioner i de övre luftvägarna

    University essay from SLU/Dept. of Clinical Sciences

    Author : Maria Neil; [2022]
    Keywords : DDSP; felläge av mjuka gommen; upprättstående struplock; stämbandsförlamning; gomsegelhöjning; T-vågor; ventrikulära arytmier; endoskopi;

    Abstract : Hästar med övre luftvägsobstruktioner har visat sig vara predisponerade för utvecklingen av arytmier. Även om dessa är relativt vanligt förekommande i återhämtningsfasen är en ökad förekomst alarmerande då ventrikulära arytmier tros vara den vanligaste anledningen till de plötsliga dödsfall som sker på banorna.

  3. 3. Deep Learning for Prediction of Falling Blood Pressure During Surgery : Prediction of Falling Blood Pressure

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Navid Zandpour; [2022]
    Keywords : Arterial Blood Pressure; Convolutional Neural Network; Supervised Learning; Hypotension; Prediction; Arteriellt Blodtryck; Faltningsnätverk; Övervakad Inlärning; Hypotension; Prediktion;

    Abstract : Perioperative hypotension corresponds to critically low blood pressure events during the pre, intra and postoperative periods. It is a common side effect of general anaesthesia and is strongly associated with an increased risk of postoperative complications, such as acute kidney injury, myocardial injury and in the worst case death.

  4. 4. Designing k-Space Filters to Improve Spatiotemporal Resolution with Sector-Wise Golden Angle (SWIG)

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Jonas Ström Seez; [2022]
    Keywords : Cardiovascular Magnetic Resonance Imaging CMR ; k-Space Filter; Sector Wise Golden-angle SWIG ; Kardiovaskulär Magnetisk Resonans Tomografi CMR ; k-rumsfilter; Sektorsvis Gyllene Vinkel SWIG ;

    Abstract : The aim of this thesis is to design and evaluate k-space weighting filters for simultaneously improving the spatial and temporal resolution of cardiovascular MRI, with the ultimate goal of improving the accuracy of quantitative flow measurements, which are important for diagnosis and follow-up of heart dysfunction. Two different k-space filters were implemented and evaluated retrospectively to already acquired data. READ MORE

  5. 5. The value of cardiac MRI texture analysis in patients with clinically suspected myocarditis

    University essay from

    Author : Evin Ina Papalini; [2021-05-10]
    Keywords : Medical physics; Myocarditis; Cardiac magnetic resonance; Texture analysis;

    Abstract : Purpose: The aim of this proof-of-concept study was to assess the diagnostic value of texture analysis (TA) based on conventional balanced steady-state-free precession (bSSFP), late gadolinium enhancement (LGE) and T2-weighted cardiac magnetic resonance imaging (CMRI) in patients with clinically suspected myocarditis. Method: A retrospective cohort study was performed based on 30 patients who underwent a comprehensive CMRI due to clinically suspected myocarditis between 2013 and 2018 at the Sahlgrenska University Hospital: 10 patients with clinical signs and positive myocardial biomarkers (Troponin T, indicating myocardial injury) as well as positive CMRI findings according to Lake Louise Criteria (LLC; group 1), 10 patients with clinical signs and positive myocardial biomarkers but negative CMRI findings according to LLC (group 2), and 10 patients with clinical signs but both negative myocardial biomarkers as well as CMRI findings according to LLC (control group).
