  1. 1. Coronary artery disease and prognosis in relation to cardiovascular risk factors, interventional techniques and systemic atherosclerosis

    Författare :Fredrik Calais; Ole Fröbert; Jerzy Leppert; Bo Lagerqvist; Stefan K James; Douwe E. Atsma; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atherosclerosis; Myocardial infarction; Coronary artery disease; Extra-cardiac artery disease; Coronary stent; Thrombus aspiration; physical inactivity; Prognosis;

    Sammanfattning : Aim: To evaluate the prognosis associated with location and severity of coronary and systemic atherosclerosis in patients with coronary artery disease (CAD) in relation to risk factors and interventional techniques.Methods: The thesis comprised six longitudinal studies based on three patient cohorts: The Swedish Coronary Angiography and Angioplasty Registry, the Västmanland Myocardial Infarction Survey, and the Thrombus Aspiration in ST-Elevation myocardial infarction in Scandinavia study, to evaluate clinical outcome relative to coronary lesion location and severity, extracoronary artery disease (ECAD), intervention techniques, and leisuretime physical inactivity (LTPI).

  3. 2. Use of EBSD Technique as a Means to Investigate the Microstructure of Engineering Materials

    Författare :Muhammad Umar Farooq; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; coronary stents.; strain induced phase transformation; EBSD; oligocrystalline structures; WC-Co;

    Sammanfattning : AbstractMaterials Science and Engineering has the aim to design or engineer the structure of a material to produce a predetermined set of properties. To be able to understand and predict the properties and observable characteristics of engineering materials, it is therefore necessary to understand their microstructure. LÄS MER

  4. 3. Invasive treatment of coronary artery disease : Aspects on antithrombotic and percutaneous treatment options

    Författare :Per Grimfjärd; Stefan James; Christoph Varenhorst; P Hedberg; Lene Holmvang; Uppsala universitet; []
    Nyckelord :PCI; STEMI; stent thrombosis; bivalirudin; heparin; bioresorbable scaffold; cangrelor; drug eluting stent; DES; Cardiology; Kardiologi;

    Sammanfattning : The outcome after percutaneous coronary intervention (PCI) has improved considerably thanks to more effective antithrombotic treatment strategies and improved coronary stents. Stent thrombosis (ST) is a rare complication to PCI associated with considerable mortality and morbidity. LÄS MER

  5. 4. Experimental studies on thrombin inhibition in acute- and chronic models of vessel wall injury

    Författare :Fredrik Scherstén; Göteborgs universitet; []
    Nyckelord :animal model; antithrombin; fibrinogen; histomorphology; melagatran; percutaneous coronary intervention; platelets; restenosis; stent; thrombin inhibition; thrombosis;

    Sammanfattning : Background: The number of percutaneous coronary interventions (PCI) performed worldwide has increased dramatically during the last decade. Complication rates have decreased over time, however the restenosis phenomenon remains an unsolved issue. Thrombin is the key regulator in the pro-coagulant state following PCI. LÄS MER

  7. 5. Influence of chronic kidney disease on presentation, treatment and outcome in patients with coronary artery disease

    Författare :Robert Edfors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background. About one third of patients with myocardial infarction (MI) have renal dysfunction (RD). Concomitant coronary artery disease (CAD) and RD is accompanied by a markedly higher risk of death and subsequent cardiovascular (CV) events. LÄS MER
